The raw material for firecrackers is sulfur. And burning sulfur will produce sulfur dioxide. Sulfur dioxide will cause acid rain. And then cause the destruction of plants and crops. The consequences are very serious. If there's too much of it. Moreover, the fog produced by the combustion of nitrogen, carbon, sulfur, and a lot of dust, which is harmful to the lungs, blood, and nerves if inhaled by the human body.
Raising geese on the environmental pollutionAccording to the "Regulations on Prevention and Control of Pollution from Livestock and Poultry Farming on a Large Scale" State Council Decree No. 643, which came into force on January 1, 2014:
Article 37 Violation of the provisions of this regulation, in the construction of livestock and poultry farms in prohibited breeding areas, farming community, by the local people above the county level *** environmental protection department shall order to stop the illegal behavior; refusal to stop the illegal behavior, shall be sentenced to 30,000 yuan or more. Violations of the law, shall be sentenced to a fine of 30,000 yuan or more than 100,000 yuan, and reported to the people *** above the county level shall be ordered to dismantle or close. In the protected area of drinking water sources to build livestock and poultry farms, farming community, by the local people above the county level *** environmental protection department ordered to stop violations, impose a fine of 100,000 yuan or more than 500,000 yuan, and reported to the people with the right to approve the approval of the people *** ordered to dismantle or shut down
Aluminum factory of the environmental pollution of the bigThis also depends on the medical equipment factory production of the product is a class of products, because of the types of medical equipment, the medical equipment factory is a class of products, the medical equipment factory is a class of products.
It also depends on which type of products the medical device factory produces, because the types of medical devices are diverse, such as a class of surgical beds, injection products, and other types, from the raw material point of view and from the processing point of view, the industrial production more or less will constitute a certain amount of pollution of the environment, but from the production process will be appropriate control will be better to realize the green manufacturing is not impossible.
apec meeting how still fireworks do not pollute the environment?
This is a noble and solemn ceremony.
You can propose,
can Zhuang national prestige, Zhuang military prestige,
better way ah,
construction, pioneering, to be better than complaining, whining.
You're right,
The expert professors and high-level engineers don't have any other good ideas.
Do gas-burning cars pollute the environment much?
Gas-burning cars have the following advantages over oil-burning cars:
1. Stable combustion, no vibration, and easy hot and cold starts.
2, compressed natural gas storage and transportation, decompression, combustion are in a strictly sealed state, not easy to leak. In addition, its gas storage cylinder after a variety of special destructive test, safe and reliable.
3, the compressed natural gas combustion safety, less carbon, reduce gas resistance and vibration, which is conducive to prolonging the service life of the engine components, reduce the number of maintenance, significantly reduce maintenance costs.
4, can reduce the engine oil consumption.
5, the use of compressed natural gas compared to gasoline, can significantly reduce the carbon monoxide, sulfur dioxide, carbon dioxide emissions. And no benzene, lead and other carcinogenic and toxic substances harmful to human health.
The use of fuel wood on the environmental pollution
Hazard 1: pollution of the air environment, endangering human health. Some data show that when burning straw, the atmosphere of sulfur dioxide, nitrogen dioxide, respirable particulate matter three pollution indices reach peak values, of which the concentration of sulfur dioxide is one times higher than usual, nitrogen dioxide, respirable particulate matter concentration is three times higher than usual, equivalent to the average daily concentration of the level of the fifth. When the concentration of respirable particles reaches a certain level, the human eyes, nose and throat containing mucous membrane parts *** larger, light cause coughing, chest tightness, tears, serious cases may lead to bronchitis.
Hazard two: cause fires, threatening the safety of people's lives and property. Straw burning, very easy to ignite the surrounding flammable material, especially in the village neighborhood, once the fire, the consequences will be unimaginable.
Hazard three: cause traffic accidents, affecting road traffic and aviation safety. The smoke formed by burning straw, resulting in reduced air visibility, visibility range is reduced, easy to cause traffic accidents.
Hazard 4: Damage to soil structure, resulting in the decline of arable land quality. Burning straw makes the ground temperature rise sharply, can directly burn, scalded to death in the soil of beneficial micro-organisms, affecting the crop on the soil nutrients fully absorbed, directly affecting the yield and quality of crops on the farm, affecting the agricultural revenue.
Hazard 5: burning straw formed by the rolling smoke, pieces of scorched earth, the image of a region's environment is the biggest damage
Practice phosphorus mud on environmental pollution and crop pollution?(1) the harm to human health: people need to breathe air to maintain life. An adult breathes about 20,000 times a day, inhaling 15 to 20 cubic meters of air. Therefore, polluted air has a direct impact on human health.
The harmful effects of air pollutants on the human body are manifold, mainly in the form of respiratory diseases and physiological disorders, as well as diseases of the mucous membrane tissues of the eyes and nose ***.
For example, in December 5-8, 1952 in London, England, the coal smog incident killed 4000 people. People called the smog of this disaster "the killer smog". According to the analysis, this is because of those days in London without wind and fog, factory chimneys and residents of heating emissions of exhaust fumes filled in the London metropolitan area for a long time, the highest concentration of soot up to 4.46 mg / m 3, sulfur dioxide daily average concentration of 3.83 ml / m 3. Sulfur dioxide after a certain chemical reaction to generate sulfuric acid droplets adhering to the soot on the or cohesion on the droplets, with the respiratory into the organs, so that the human being The sulfur dioxide is a chemical reaction that produces a sulfuric acid droplet that sticks to the fume or condenses on the droplets and enters the organs with the breath, making people sick or accelerating the death of the chronically ill.
From the above example, it can be seen that the high concentration of pollutants in the atmosphere, can cause acute pollution poisoning, or make the disease worse, and even in a few days to kill thousands of people. In fact, even if the concentration of pollutants in the atmosphere is not high, but the human body for years and years to breathe this polluted air, will cause chronic bronchitis, bronchial asthma, emphysema and lung cancer and other diseases.
(2) the harm to plants: air pollutants, especially sulfur dioxide, fluoride and other harm to plants is very serious. When the concentration of pollutants is very high, it will produce acute harm to plants, so that the surface of the plant leaf injury spot, or directly make the leaf wither and fall off; when the concentration of pollutants is not high, it will produce chronic harm to plants, so that the plant leaves fade green, or on the surface of the surface can not be seen what harm to the symptom, but the plant's physiology has been affected, resulting in a decline in plant production, quality deterioration.
(3) on the weather and climate: the impact of air pollutants on the weather and climate is very significant, can be illustrated from the following aspects:
① Reduce the amount of solar radiation reaches the ground: from factories, power stations, automobiles, home heating devices to the atmosphere emits a large number of particles of smoke and dust, so that the air has become very muddy, blocking sunlight, so the amount of solar radiation reaches the ground is reduced. The amount of solar radiation reaching the ground is reduced. It has been observed that on days when the smog in large industrial cities does not dissipate, the amount of direct sunlight reaching the ground is nearly 40% less than on days when there is no smog. In cities with high levels of air pollution, this can lead to a lack of sunlight for people, plants and animals to grow and develop.
② Increase the amount of atmospheric precipitation: particles from large industrial cities, many of which have the role of water and gas condensation nuclei. Therefore, when the atmosphere has some other precipitation conditions with it, there will be precipitation weather. In the downwind areas of large industrial cities, more precipitation. Tmall US Puweixin tips: haze weather travel remember to do a good job of protection.
③ Acid rain: Sometimes, the rain falling from the sky contains sulfuric acid. This acid rain is an atmospheric pollutant sulfur dioxide after oxidation to form sulfuric acid, with the natural precipitation fall formation. Sulfuric acid rain can make a large area of forests and crops destroyed, can make paper, textiles, leather products, etc. corrosion broken, can make the metal antirust paint deterioration and reduce the protective effect, but also corrosion, pollution of buildings.
④ Increase the atmospheric temperature: In the large industrial cities over the air, due to a large number of waste heat emissions into the air, so the temperature of the air near the ground than the surrounding suburbs to be higher. This phenomenon in meteorology is called "heat island effect".
⑤ Impact on global climate: In recent years, people have gradually noticed the impact of air pollution on global climate change. After research, it is believed that carbon dioxide has a significant role in the various air pollutants that may cause climate change. About 50 per cent of the large amount of carbon dioxide emitted into the atmosphere from the countless chimneys and other exhaust pipes on Earth remains in the atmosphere. Carbon dioxide absorbs long-wave radiation from the ground, increasing the temperature of the air in the near-surface layer, which is called the "greenhouse effect". It is roughly estimated that if the carbon dioxide content in the atmosphere increases by 25%, the near-surface air temperature will increase by 0.2℃. If it increases by 100%, the near-surface temperature can increase by 1.6℃. Some experts believe that the atmospheric carbon dioxide content according to the current rate of increase, after a number of years will make the North and South Poles of the ice melting, resulting in global climate anomalies.
Is the leather factory a big pollution to the environment? What are the main sources of pollution? Thank youHello, leather factory pollution on the environment has a great impact, mainly through the following aspects of analysis:
1. Tanning production generally includes: preparation section, tanning section, finishing section;
2. Production process:
Raw hides through the washing - soaking water --Dehairing - Soaking - De-fleshing - Purifying - Water washing - Softening - Tanning -washing - softening - washing - acid dipping - chrome tanning --Chipping - Neutralizing - Dyeing - Fueling - Finishing - Finished product -Finishing -Finished products
Pollution Sources and Pollution Factors:
Tannery Wastewater (COD, BOD5, SS, Sulfide, Chloride, Trivalent Chromium, Phenol, PH, Chroma, Vegetable and Plant Oils, etc.)
Air Pollution (TSP, PM10, SO2, NOX, NH3, H2S, bad odor, etc.)
Solid waste (waste wool, meat film, shredded hides, trimmings, leather scraps, sludge from sewage station, boiler cinders)
Noise (plant noise)
In addition to boiler fumes, tannery exhaust includes volatiles of organic solvents used in the production and bad odors from the storage of raw hides, the production process and the sewage station. pollutants.
The main sources of wastewater: during the production and processing of raw hides, a large amount of protein and fat enter into wastewater and waste residue; a large amount of chemical raw materials used such as acids, alkalis, salts, sodium sulfide, lime, chrome tanning agent, dyes and so on have a large part of them enter into the wastewater. Wastewater in tanning mainly comes from the preparation, tanning and wet processing section, in which the wastewater discharge and pollution load of the pre-tanning preparation section account for 70% of the total amount of wastewater in tanning; tanning stage and wet processing stage account for 8% and 20% of the amount of wastewater, respectively;
Leather wastewater is alkaline, deep color, containing proteins, fats, dyes, chromium, sulphide, chlorides, and other inorganic substances belonging to the toxic and harmful wastewater. One of the de-chroming process and gray alkali dehairing waste sulfide seriously exceeded the standard, these two streams of wastewater water tanning industry wastewater management focus.
Zhongxian carton factory on the environmental pollution?
The upstairs answer is very comprehensive, any production enterprise will have a certain impact on the environment, if you want to understand in depth on the paper enterprise show. above the factory more than enough for you to consult
In the face of environmental pollution, fireworks and firecrackers industry will declineXinhua Beijing on February 6, the new media (reporter Qin Juji Liu Shuo Zhang Manzi) With more and more areas to introduce a ban on the release of fireworks, restrictions on the release of fireworks, and the series of anti-corruption measures in recent years to strictly enforce the regulations. Coupled with a series of anti-corruption measures in recent years to strictly prohibit the purchase of public funds, fireworks and other acts of gift, the traditional fireworks industry is facing unprecedented pressure, the market has gradually narrowed.
The reporter interviewed some fireworks manufacturers and distributors found that the harsh market conditions have made many manufacturers and distributors call can not eat, some small businesses simply seek to change the line, while a certain scale of large enterprises are seeking product transformation and upgrading in an attempt to regain the momentum.
The ban on discharge restrictions under the encounter "severe winter"
Lunar Lunar 23rd is the date in previous years, Changchun fireworks on sale, many dealers are often a week in advance to start stocking up, but this year in the main city of Changchun City, but can not see the fireworks distribution stalls. 2014 August, with the "Changchun City, the discharge of fireworks safety management regulations" introduced. In August 2014, with the "Changchun City, fireworks safety management regulations" was introduced, Changchun City, within the fourth ring road area year-round ban on the sale and discharge of fireworks.
The reporter previously visited some fireworks storage and transportation, dealers found that a few years ago, the lively wholesale scene these two years has been difficult to see, the average daily sales have declined year after year, some of the fireworks wholesale business customers less than half of the original, and to the small and medium-sized retail customers. In order to regain the market, dealers have to significantly compress the profit margin "tear sale".
According to the Panda fireworks sales staff, because the Year of the Sheep Spring Festival fireworks sales time is shorter than in previous years, so this year, compressed the amount of stock, the total amount of stock*** counted 150,000 boxes, merchants ordering 20% less than the same period last year.
Jilin Province, a large fireworks sales enterprise sales person in charge of Mr. Wang told reporters that the current market situation for them is "winter". He told reporters that in the past, annual sales can still have a few million dollars, but these years of continuous decline, this year is only about half of last year, the company's current stock quantity is enough to sell for several years, the goods pressed quite a lot of money, if the market continues to deteriorate, can only consider doing something else.
December 30, 2014, Nanchang *** News Office government microblogging microblogging @ Nanchang release release message said: "Recently, frequent haze weather conditions around the world, in order to reduce the emission of pollutants, to maintain good air quality in Nanchang, scheduled for the evening of December 31 in the Ganjiang River on the Jiangxinzhou fireworks display activities canceled. " Jiangxi Province Lidu Fireworks Group Co., Ltd. deputy general manager Hou Zhongping said, the central eight provisions introduced in the past two years, many large-scale fireworks activities have been canceled one after another, the company is a loss. For some small and medium-sized manufacturers producing ordinary public lighting products, due to the sharp decline in market purchasing power, the days are also increasingly difficult.
Environmental fireworks can save the decline?
The reporter learned that, due to pollution of the environment to create haze "allegations", many fireworks manufacturers have turned to environmentally friendly fireworks research and development and production. Hou Zhongping told reporters that the current Li Du Group production of 70% or 80% of the products are environmentally friendly products, can effectively reduce environmental pollution.
The reporter learned that the environmentally friendly fireworks color will also be more beautiful, less smoke, and currently exists mainly in the combination of fireworks, wire incense class and children's fireworks and other products. Panda fireworks sales person in charge said the company in 2014 developed environmentally friendly fireworks using sulfur-free launch technology, fireworks do not contain sulfur yellow, burning gas does not contain sulfur dioxide. And the charge is reduced by 6%, pollution and cost are down, this environmentally friendly fireworks accounted for 70% of the total stock of fireworks this year.
The person in charge of a fireworks sales enterprise in Jilin Province told reporters that the company is actively preparing for the sale of environmentally friendly fireworks. "The beginning of next year will be a large number of market, now many manufacturers in Jiangxi and Hunan are in production, the supply will gradually more." A responsible person said.
For the public, the price of environmentally friendly fireworks will be too high is more concerned about their problems. In this regard, some of the artillery production enterprise responsible person said, is now in the environmental protection fireworks R & D and the market in the primary stage, R & D costs are relatively high, the market price will be higher than the traditional products, but with the mass production of products, the price will drop, and some companies in order to capture the market, has been the initiative to sacrifice the profits of the price down.
Guide the transition is the "king's way"
In recent years, due to frequent accidents in the fireworks industry and "winter" sad, the management of the production of strict rectification of enterprises, trying to reduce the scale of production to guide the development of the market. After a number of rectification, Jiangxi Province, fireworks production enterprises will be more than 2000 from 2013, down to more than 1,000 by the end of 2015. According to the reporter, many local fireworks production and sales enterprises have also experienced a "reshuffle" process in the past two years.
Jiangxi Provincial Committee of the Chinese People's Political Consultative Conference member Chen Jian said, for the fireworks and fireworks enterprises, I am afraid that the shutdown, production restrictions is not a permanent solution. He believes that the closure of some substandard fireworks enterprises at the same time, *** should strive to take a variety of measures to support the transformation of enterprises to guide the healthy development of the industry; at the same time, but also for some large-scale enterprises to support, strengthen the environmental protection of product research and development efforts to cultivate a new product consumer market.
Rao Hui, chief engineer of Nanchang Environmental Monitoring Station, from the perspective of protecting the environment and establishing a new style, to guide the public to choose to burn non-polluting, powerful environmentally friendly products, both to reduce environmental pressure, but also to make the New Year's Eve more flavorful, two birds with one stone.
