1 environmental engineering technical specifications in the energy saving and emission reduction in the impact
1.1 China's energy saving and emission reduction work in the status quo
By a 2001~2008 domestic GDP growth rate and industrial energy consumption rate of the statistical data can be seen: from 2002, China's energy consumption gradually exceeded the rate of growth of GDP, and reached its peak in 2004, twice the rate of GDP, the energy consumption of the country's energy consumption, energy consumption and industrial energy consumption rate. In 2004, it peaked at more than twice the GDP. In 2006, it was reduced to the same value as GDP. With the deepening of the State Council's attention to environmental governance, and the preparation of a large number of technical specifications for environmental engineering, China's energy consumption fell from 4.21% in 2008 to 4.06%. In 2009, the installation rate of energy-saving and emission reduction equipment in some provinces and cities of China reached 67%, such as a power generation enterprise in Shaanxi Province, after the implementation of the "Dust Removal Technical Specification for the Electric Power Industry", the installation of exhaust gas purification device particles removal rate increased by 37%, the recovery rate of the oil agent increased by 23%, and the quality of the air in the workshop complies with the standards of the Ministry of Engineering, with no obvious irritating odors. Through the release of various environmental engineering technical specifications, provides a reliable energy saving and emission reduction technical guidance to improve the protection of bad environment.
1.2 The impact of environmental engineering technical specifications in energy conservation and emission reduction
1.2.1 Improvement of energy conservation and emission reduction in various industries
Some small chemical production enterprises, due to the small size of the enterprise, located in the remote area, the enterprise leaders do not pay attention to pollution control, allowing industrial waste emissions, aggravate the deterioration of the environment of the surrounding areas, which in the long run caused a large number of irreversible loss of resources. In the long run, this has caused a lot of irreparable loss of resources. The general requirements of the environmental engineering specifications will provide for waste emissions and the degree of impact on the surrounding environment, forcing some enterprises to deal with industrial waste in accordance with the provisions of the law to reduce China's "Environmental Protection Law" in the blind spot.
Some large enterprises will also be due to the past no specialized technical specifications to measure the "three wastes" management standards. And energy saving and emission reduction is not enough attention, through the study of environmental engineering technical specifications, improve the degree of attention to energy saving and emission reduction, but also set up an internal charter to ensure that energy saving and emission reduction work is done efficiently.
1.2.2 Improvement of energy saving and emission reduction treatment level in various industries
By the end of 2012, China has launched 99 environmental engineering technology regulations, of which 55 have been formally implemented, the remaining 44 are still in the continuous preparation of supplementation to ensure that the technical specifications of the specialization and comprehensiveness. These norms are mainly composed of basic, technical two kinds of composition; technology is divided into control technology, repair technology, perfect technology, in addition to general technology also corresponds to different pollutants to provide different treatment technology, involving nearly 40 kinds of enterprises to provide supporting treatment programs. The technology category also includes "environmental engineering technical specifications for the development of technical guidelines" to help enterprises in the treatment of pollution if they encounter new problems, but also based on the norms of their own development, in the past, some enterprises for some pollutants, and no professional treatment methods only to imitate the treatment methods of other industries, through the study of environmental engineering specifications to find the right for their own pollution, combined with the specialized scientific management, not only to save the resources and improve the efficiency of energy saving and emission reduction. Resources also improve the efficiency of energy saving and emission reduction.
1.2.3 Improve the quality of environmental impact assessment
Every project in the investment in the construction of the environmental impact assessment will be involved in the construction of the project may be deterioration of the environmental problems in the construction of the prediction, and put forward solutions. The environmental engineering specification not only provides reference indexes for it, but also helps it to find the source of pollution out of the source and provide improvement programs. For example, the Technical Specification for Textile Dyeing and Finishing Industrial Wastewater Treatment Project points out that different pollutant elements will pollute water resources in the refining, bleaching, dyeing, and washing of grey fabrics, and the environmental impact assessment department can formulate a scientific and effective treatment plan based on the different pollutants and cooperate with the relevant links to improve the quality of evaluation |4].
2 environmental engineering technical specifications in energy saving and emission reduction
Environmental engineering technical specifications provide a large number of advanced pollution control technology, promoting the development of China's environmental protection engineering next will be from the water pollution category, solid waste pollution category, air pollution category three aspects of environmental engineering in energy saving and emission reduction.
2.1 water pollution category
Environmental engineering technical specifications not only involves industrial wastewater discharge treatment, but also for hospitals, such as career-oriented units of sewage treatment provisions. Through physical, chemical, biological three aspects of joint management of water pollution problems gas to the "Hospital Engineering Technical Specification" as an example, the specification to improve the treatment of water pollutants in medical institutions for the preparation of ideas, the preparation of the focus on the optimization of indoor and outdoor drainage network design. Through the design of clean and sewage diversion, clear water is recycled and reused through the pipeline network after testing, and sewage from non-infectious disease medical institutions is discharged through secondary coagulation and sedimentation, and into the disinfection pool for ultraviolet disinfection, and sludge is recycled and treated. Strictly monitor the temperature, pH value and pollutant concentration during treatment to ensure that the discharge of sewage for the environmental impact of compliance with the regulations, and reuse catalytic resources and recyclable resources to achieve the purpose of energy saving and emission reduction.
2.2 Solid Waste Pollution
Solid waste management technology is divided into general and special waste treatment category, the main role is through the collection and treatment, classification, recycling and collection of incineration of four, for high temperature steam, medical waste should be special disinfection and finally according to the type of landfill or incineration. In the general solid waste treatment, will first be sent to the solid waste disposal site, classification and treatment of a revile paper waste can be sent back to the factory for processing and reuse, and some household waste can be used as fertilizer. The rest of the non-recyclable waste will be treated with special treatment and then incinerated or landfilled. Solid waste in the treatment plant storage process will produce garbage leachate, this liquid if not treated in a timely manner will be fermented to produce acidic, polluting groundwater. Therefore, the environmental engineering technical specifications also introduced "leachate engineering technology treatment specifications" leachate treatment methods, through dry sludge landfill or concentrate coagulation and filtration landfill, reduce the degree of pollution, play a role in energy saving and emission reduction.
2.3 Air Pollution
Air pollution in all types of enterprises, thermal power plant pollution is higher, nitrogen oxides and soot emissions accounted for the national industrial emissions of 2 / 3 and 1 / 3. Therefore, the thermal power plant chemical process design and exhaust gas treatment specifications more. Such as desulfurization tower process changes
Increase the number of spraying, and in each layer of the installation of sewage pipes and control valves to achieve the effect of desulfurization purification. Installation of mist eliminator at the top of the absorption tower to absorb dust particles to reduce sulfide emissions. By transforming the desulfurization tower process arrangement to improve the flexibility of operation, extend the contact area of desulfurization liquid and flue gas not only improves the efficiency of desulfurization, but also make the exhaust flue gas clean and clean, play a role in reducing emissions. In the treatment process to increase the circulation pump, and circulating sedimentation tank set up, through filtration and adsorption processing, extraction of which can be recycled substances for resource reuse, and play a role in energy saving.
