Energy conservation and emission reduction technology support action implementation work plan
I. Energy saving and emission reduction technology status quo Energy consumption and energy saving technology status The energy consumption structure of our city is mainly coal. In the energy consumption structure of XX, coal and coke accounted for 64.1%; the comprehensive energy consumption of 10,000 yuan in the city was XX years. 2.77 tons of standard coal fell to 2.09 tons of standard coal in XX, a decrease of 24.5%, but still higher than the provincial average of 0.92 tons of standard coal. The city's large-scale industrial high-energy-consuming industries are mainly concentrated in the steel, electric power, building materials and other industries, and its comprehensive energy consumption accounts for 97% of the total industrial energy consumption of all scales. In terms of power consumption, the city's electricity consumption in XX was 3.21 billion kilowatt-hours, and in XX, it was 4.31 billion kilowatt-hours, with an average annual growth rate of 6.1%. Among them, the electricity consumption of the secondary industry accounts for nearly 80% of the total electricity consumption in the whole society, almost all of which is industrial power consumption. In addition, the city's clean energy use rate increased from 21.97% in XX to 35.5% in XX.
The city's social power consumption and the electricity consumption of various industries are showing a growing trend, indicating that the economy is in a stage of rapid development, and the demand for energy is increasing. Moreover, there are many high-energy industries, and the level of major industrial equipment is not high. The utilization rate is low, and the energy saving and consumption space is large.
The city focused on energy conservation and consumption reduction in key industries, carried out innovative technical research, broke through a number of bottleneck technologies, developed and applied a number of major energy-saving new technologies, new processes and new equipment.
Iron and steel enterprises focused on promoting “three-three-three utilization”. In XX, the comprehensive energy consumption of steel enterprises in the city dropped by 8.89%. Electrochemical Group Co., Ltd. has established a cogeneration project. After adopting the circulating boiler, it follows the principle of energy cascade utilization, saving 11,000 tons of raw coal and 600,000 tons of water. In China, the first to seize the wind power equipment market, Motor Group Co., Ltd. broke through the three major technical bottlenecks of the complete system integration, unit control system and large-scale direct-drive low-speed wind turbine production of MW direct-drive wind turbines, which became the earliest established in the country. One of the three industrial bases for wind turbine manufacturing. In the transportation field, it has broken through a number of key technologies such as hybrid vehicles.
Despite this, the city still does not form a systematic industrial energy consumption indicator system and project energy conservation assessment index system; the energy structure is not reasonable enough, efficient and clean energy is lacking; the development and promotion of high-efficiency energy-saving technology is insufficient.
Pollution emission and emission reduction technology status The city has low resource utilization rate, high pollutant emission intensity, and extensive environmental hazards caused by extensive operation. The environmental capacity of some areas has become saturated, environmental pollution has increased, and ecological risks have increased. Its ecological and environmental issues have undergone profound changes in terms of type, size, structure, nature and extent of influence. Mainly manifested in:
1. The problem of water pollution is outstanding. In the XX year, there were 10 projects with excessive monitoring in the river section. Among them, ammonia nitrogen, petroleum, and chemical oxygen demand were the main pollution factors, and heavy metal pollution of cadmium, mercury and arsenic exceeded national standards. The water pollution in the urban section is mainly characterized by industrial pollution and combined pollution of urban domestic sewage, and the urban domestic sewage treatment rate is only 23%.
2. Urban air quality is poor. The emission of exhaust pollutants is mainly concentrated in the advantageous industries of thermal power, building materials, chemical industry and metallurgy, etc., and its emissions account for 88% of the total emissions of exhaust pollutants in the city. Industrial exhaust emissions showed an overall increase trend, from 62.07 billion standard cubic meters in XX years to 75.03 billion standard cubic meters in XX years. The city's sulfur dioxide, soot, dust emissions are among the highest in the province, and also belong to China's heavy acid rain zone.
3. Solid waste pollution is aggravated. The growth rate of industrial solid waste increased from 1.966 million tons in XX to 4.366 million tons in XX year; the harmless treatment rate of domestic garbage needs to be further improved.
4. Ecological risks are increasing. Some “three wastes” discharged by metallurgical and chemical enterprises have caused a certain degree of pollution to the surrounding soil. The chromium and other pollutants in the soil and groundwater of the old industrial areas are generally exceeding the standard, and the soil cadmium exceeding the standard is also present on both banks of the river.
The “three wastes” emissions of our city have shown an increasing trend year by year, reflecting the low level of industrial clean production and excessive resource consumption. Although the industrial categories of the city are complete, the industrial chain is short, and the level of resource recycling between enterprises is low. The task is very difficult.
In recent years, a series of key technologies for efficient use and reduction of resources have been developed and promoted. For example, Steel Group Co., Ltd. uses ceramic membrane filtration treatment technology to achieve recycling of 60 million tons of sewage; Hunan Nonferrous Fluorine Chemical Co., Ltd. replaces quicklime with calcium carbide slag, with a monthly dosage of about 6,000 tons; Power Generation Co., Ltd. uses desulfurization Gypsum replaces gypsum to produce gypsum board, which realizes comprehensive utilization of 200,000 tons of desulfurized gypsum. However, there is still a great demand for environmental technologies for pollutant emission reduction in our city, mainly reflected in: key technologies for clean production in key industries such as iron and steel, and key technologies for circular economy in Zhuyugang Industrial Park; waste in the old industrial area of township is harmless. Chemical and resource recycling technologies; interaction and regulation technologies of atmospheric, water and soil complex environmental pollution in key areas; regional atmospheric fine particulate matter, nitrogen oxides and air toxic and harmful pollutants control technologies.

Process.
The city's social power consumption and the electricity consumption of various industries are showing a growing trend, indicating that the economy is in a stage of rapid development, and the demand for energy is increasing. Moreover, there are many high-energy industries, and the level of major industrial equipment is not high. The utilization rate is low, and the energy saving and consumption space is large.
The city focused on energy conservation and consumption reduction in key industries, carried out innovative technical research, broke through a number of bottleneck technologies, developed and applied a number of major energy-saving new technologies, new processes and new equipment.
Iron and steel enterprises focused on promoting “three-three-three utilization”. In XX, the comprehensive energy consumption of steel enterprises in the city dropped by 8.89%. Electrochemical Group Co., Ltd. has established a cogeneration project. After adopting the circulating boiler, it follows the principle of energy cascade utilization, saving 11,000 tons of raw coal and 600,000 tons of water. In China, the first to seize the wind power equipment market, Motor Group Co., Ltd. broke through the three major technical bottlenecks of the complete system integration, unit control system and large-scale direct-drive low-speed wind turbine production of MW direct-drive wind turbines, which became the earliest established in the country. One of the three industrial bases for wind turbine manufacturing. In the transportation field, it has broken through a number of key technologies such as hybrid vehicles.
Despite this, the city still does not form a systematic industrial energy consumption indicator system and project energy conservation assessment index system; the energy structure is not reasonable enough, efficient and clean energy is lacking; the development and promotion of high-efficiency energy-saving technology is insufficient.
Pollution emission and emission reduction technology status The city has low resource utilization rate, high pollutant emission intensity, and extensive environmental hazards caused by extensive operation. The environmental capacity of some areas has become saturated, environmental pollution has increased, and ecological risks have increased. Its ecological and environmental issues have undergone profound changes in terms of type, size, structure, nature and extent of influence. Mainly manifested in:
1. The problem of water pollution is outstanding. In the XX year, there were 10 projects with excessive monitoring in the river section. Among them, ammonia nitrogen, petroleum, and chemical oxygen demand were the main pollution factors, and heavy metal pollution of cadmium, mercury and arsenic exceeded national standards. The water pollution in the urban section is mainly characterized by industrial pollution and combined pollution of urban domestic sewage, and the urban domestic sewage treatment rate is only 23%.
2. Urban air quality is poor. The emission of exhaust pollutants is mainly concentrated in the advantageous industries of thermal power, building materials, chemical industry and metallurgy, etc., and its emissions account for 88% of the total emissions of exhaust pollutants in the city. Industrial exhaust emissions showed an overall increase trend, from 62.07 billion standard cubic meters in XX years to 75.03 billion standard cubic meters in XX years. The city's sulfur dioxide, soot, dust emissions are among the highest in the province, and also belong to China's heavy acid rain zone.
3. Solid waste pollution is aggravated. The growth rate of industrial solid waste increased from 1.966 million tons in XX to 4.366 million tons in XX year; the harmless treatment rate of domestic garbage needs to be further improved.
4. Ecological risks are increasing. Some “three wastes” discharged by metallurgical and chemical enterprises have caused a certain degree of pollution to the surrounding soil. The chromium and other pollutants in the soil and groundwater of the old industrial areas are generally exceeding the standard, and the soil cadmium exceeding the standard is also present on both banks of the river.
The “three wastes” emissions of our city have shown an increasing trend year by year, reflecting the low level of industrial clean production and excessive resource consumption. Although the industrial categories of the city are complete, the industrial chain is short, and the level of resource recycling between enterprises is low. The task is very difficult.
In recent years, a series of key technologies for efficient use and reduction of resources have been developed and promoted. For example, Steel Group Co., Ltd. uses ceramic membrane filtration treatment technology to achieve recycling of 60 million tons of sewage; Hunan Nonferrous Fluorine Chemical Co., Ltd. replaces quicklime with calcium carbide slag, with a monthly dosage of about 6,000 tons; Power Generation Co., Ltd. uses desulfurization Gypsum replaces gypsum to produce gypsum board, which realizes comprehensive utilization of 200,000 tons of desulfurized gypsum. However, there is still a great demand for environmental technologies for pollutant emission reduction in our city, mainly reflected in: key technologies for clean production in key industries such as iron and steel, and key technologies for circular economy in Zhuyugang Industrial Park; waste in the old industrial area of township is harmless. Chemical and resource recycling technologies; interaction and regulation technologies of atmospheric, water and soil complex environmental pollution in key areas; regional atmospheric fine particulate matter, nitrogen oxides and air toxic and harmful pollutants control technologies.
