Huzhou is named after the lake, which is one of the main upstream water sources of Taihu Lake, so the impact of the quality of water in Huzhou is great. And nowadays, the water in the city of Huzhou is polluted is every Huzhou people have witnessed ****.
My home is located next to the "Mother River", as long as a walk towards the river in front of the window, you can see a large area of green aquatic plants floating on the surface of the Mother River, or maybe part of them are microorganisms. Anyway, the green color was very unnatural and uncomfortable to look at, so I judged this phenomenon through my knowledge in junior high school that it should be the "water bloom" phenomenon caused by eutrophication and pollution of the water body. In addition to these plants, microorganisms, but also from time to time to see the river floating in the larger size of the domestic garbage, those small size of the garbage, needless to say, but also can be seen at all times. In addition to the serious conditions on the surface of this mother river, if you take a closer look into the river water, you will feel that the water is very dark in color and strangely deep. When encountering a river like this, I guess whoever it is would guess the reason for its creation.
(i). Excessive application of chemical fertilizers will make the soil contains too much nitrogen and phosphorus elements, they will flow with the water to other bodies of water, coupled with the large number of people using chemical products such as phosphorus-containing detergents, so that rivers, lakes and other bodies of water in the nitrogen and phosphorus content of a large number of increases (some estimates, the earth's current amount of industrial nitrogen fixation has been the nature of biological nitrogen fixation of 1 times). Abundant nutrients in the water to make algae bloom, will appear in freshwater "water bloom" phenomenon, in the ocean will appear "red tide" and so on. When these algae die, the bacteria decomposition of these organic materials need to consume a large amount of dissolved oxygen in the water body, so that the body of water in need of oxygen organisms (such as fish, mollusks, etc.) a large number of deaths. At this point, the water body will be blackened and become foul-smelling, and the water quality will seriously deteriorate.
(ii). On several occasions, I have seen residents living nearby dumping all kinds of household garbage into the river, even plastic foam. In addition, I have also seen residents on the other side of the river cleaning toilets or brushing their teeth in the river water. People may think that brushing their teeth is a trivial matter, but the water used for brushing teeth over a long period of time can also pollute the river water! However, the most unbelievable thing is that there are still people who do laundry in such dirty water. However, these behaviors are not incomprehensible, they are probably the manifestation of the dark side of human character, which can also be seen in the larger part of the citizens of Huzhou is very lack of moral quality. However, I really do not understand, the river is polluted to the surrounding residents have what good not, the surrounding residents even watched the mother river water quality deteriorating, but still did not stop the behavior of pollution of the river! This really let down the hard work of sanitation workers, but also let the "Mother River" three words stained.
(iii). Through the online information, showed that the typhoon will also cause water pollution: "Maysa" brought torrential rains caused part of the city's underground drop pool water pollution, but also affects the nearby residents of the living water, resulting in the blockage of the nearby underground waterway, there is also the phenomenon of contaminated water backflow. The quality of this water is easily contaminated by bacteria, E. coli and other infectious agents. Once consumed by residents, they can cause intestinal diseases such as diarrhea, typhoid and dysentery.
The above three points are our summary of the possible causes of pollution of water bodies in Huzhou City.
In our Huzhou, due to the rapid development of township industry, a large number of mining and stone washing, coupled with agricultural surface pollution (also known as non-point sources of pollution, mainly refers to the rural irrigation water runoff, rural wastewater discharged in the unorganized discharge of wastewater, surface runoff and other wastewater sewage. Decentralized discharge of small amounts of sewage, can also be included in the surface pollution sources), the water flowing into Lake Taihu perennial for the three types of water bodies (Class III water bodies: for the centralized drinking water sources of secondary protection areas, a fish protection zone, swimming areas, etc.). Gradually, even our lake named Huzhou drinking water quality is not optimistic. As most of the water plant intake site is not reasonable, coupled with the scope of the water source protection zone is not clearly delineated, the management is not standardized, it is easy to cause environmental pollution of water sources.
Huzhou City District, two water plants, the city's northern water plant intake on the other side of the river, farmers throw garbage, often contaminated water quality; City West water plant in the water protection zone in the main channel, often suffered from the boat people living and fuel oil pollution generated by the protected area there is actually an old boat trading wharf. Jiangnan town Nanxun, not only the raw water of its water plant is often four types of water bodies (Ⅳ water bodies: industrial water areas, the human body is not in direct contact with the recreational water areas), more worrying is that the water plant is close to the town's hospitals, susceptible to the threat of medical wastewater. Originally, Huzhou got the benefit of the West Campsis River flushing, the quality of drinking water has been very good, today's situation can not help but make people worried.
In early 2006, our Huzhou had a storm caused by chemicals discharged into the tap water source, which led to a city full of panic at the time, but also thanks to the government decisively dealt with the public **** crisis.
The pollution incident happened on February 10th. On that day, the Huzhou City Hydrological Station extracted water samples from two monitoring points in Huzhou Yangjiabu and Chengbei Bridge, and the staff was surprised to find that the water samples exceeded the phenol standard by a serious margin. Huzhou City Hydrological Station immediately reported to the municipal government. Huzhou Municipal Environmental Protection Bureau after receiving an emergency call from the Huzhou Municipal Government, environmental monitoring team and accident investigation team immediately rushed to the scene that night. In the collection of water samples for testing and processing, found that the cause of pollution is the Huzhou red European new synthetic materials limited company sewage discharge port water samples volatile phenol abnormal. Huzhou City environmental protection department testing, red European company discharged sewage volatile phenol concentration exceeded the standard, including sewage outfall volatile phenol concentration of up to 172mg / L, exceeding the standard 85 times. The concentration of volatile phenols in the rainwater well in front of the resin workshop of Hong'ou Company was as high as 89.8mg/L, exceeding the standard by 17959 times; the sewage pipe network outside Hong'ou Company was affected by the company's discharged effluent, of which the concentration of volatile phenols in the sewage wells in the intersection of Caifeng Road and Ricun Road was as high as 186mg/L, exceeding the standard by 92 times; the concentration of volatile phenols in the rainwater pipes outside Hong'ou Company was seriously exceeding the standard. In the monitoring of the stormwater wells exceeded most of the times in the hundreds to thousands, some as high as tens of thousands, of which Ji Xiang Road stormwater wells in the noon of February 12 volatile phenol concentration of up to 270mg / L, exceeding the standard by more than 50,000 times. Such a serious volatile phenol (belonging to the phenolic substances with volatility, phenol and its compounds is a toxic substance, high concentrations of phenols and their compounds into the human body, can cause acute poisoning, and even cause coma and death) pollution, if not the relevant agencies to find, manage in time, the consequences must be unimaginable.
Not only water pollution, any pollution pathways are varied, only rely on each and every one of the good sense of environmental protection may be realized to reproduce the beautiful scenery of Huzhou in the past ah!
Related Recommendations:
Government: 1. Strengthen the standardized management of water withdrawal and water use, and strict licensing of water withdrawal and paid use of water system. Any unit or individual who needs to take water resources directly from rivers, lakes or underground must apply to the relevant departments in accordance with the provisions of the relevant departments to obtain permission before taking water, and require them to pay water fees in accordance with the law, and strictly in accordance with the provisions of water withdrawal and use of water and do not waste water resources.
2. Widely publicize the importance of the protection of water resources, through a variety of media to carry out publicity and education on water resources, and enhance the awareness of the whole society of water conservation and protection.
3. Strengthen the construction of water conservancy projects, take effective measures to improve the ecological environment and increase the utilization rate of water resources.
4. Strengthen law enforcement efforts to maintain normal development and utilization of water resources, and intensify the crackdown on the wanton waste and exploitation of water resources.
Residents: 1. use phosphorus-free detergents;
2. minimize the use of chemical-containing items;
3. make it a point not to dump household garbage into the river.

Conclusion:
At present, the water pollution in Wuxing District is serious, the government must increase the management, protection and monitoring system of the water quality, the residents must regulate their own behaviors, the enterprises should take pride in the protection of water resources, and everyone should take shame in wasting and polluting water resources. Water - the source of life, everyone has the responsibility to protect and conserve water resources, leaving it, not only us, every living thing on earth will cease to exist. Water is so important, but it is not inexhaustible, it needs to be treasured by everyone
