Coal is the main energy source and raw material for the chemical industry. Coal chemical industry can produce a variety of chemical products and energy chemicals. The production process is different, and the pollution and its severity are different. For example, coking, calcium carbide, gas generation, and direct coal-fired processes all have serious pollution and have not been effectively treated for a long time.
In general, there are three main characteristics for the prevention and control of coal chemical pollution: First, as a whole, as long as it fully reproduces, takes effective measures, and integrates various advanced and applicable new environmental protection technologies and new equipment, it pays enough infrastructure investment. With frequent operating expenses and strict day-to-day management, most of the pollution can be managed and controlled. Second, the focus and difficulty of coal chemical pollution is sewage treatment. The chemical oxygen demand and biochemical oxygen demand in sewage are relatively high, and some biochemical degradation is difficult. Harmless treatment of sewage also requires a great deal of effort, and some still require scientific research. Third, the development of circular economy has attracted much attention. China's energy utilization rate is only 33%, and the total recovery rate of mineral resources is 30%, which is 10% and 20% lower than the foreign advanced level respectively. At present, the development of circular economy has changed from concept to action and has been rapidly developed nationwide. Chemical systems are being implemented in conjunction with actual conditions and many new developments have occurred. It should be said that coal chemical industry can accomplish a lot in turning waste into treasure and comprehensive utilization.
Coal chemical industry is an important part of China's chemical industry. The way for the development of coal chemical science is to take the scientific concept of development as a guide, with reform and opening as the driving force, taking sustainable development as the cornerstone, and improving the ability of scientific and technological innovation as a means, taking the market as the guideline, and taking an overall consideration of China’s coal, oil, natural gas, and coal seams. The scientific, rational and efficient use of fossil resources such as gas and coke oven gas as well as renewable resources has enabled our country to form a product field that combines Petrochemicals and coal chemical industry and has its own advantages, complement each other, and form an overall conformity with China’s national conditions and scientific and rational. The raw material structure, product structure, technical structure and enterprise structure enhance international competitiveness and accelerate the modernization of the chemical industry.
Coal chemical industry is a resource-consuming industry. Traditional coal chemical industry is an industry with high energy consumption, high emission and high pollution. The development of modern coal chemical industry should be based on energy saving, emission reduction and pollution control as a breakthrough to change the mode of development, strategic structural adjustment, and strive to improve sustainable development capabilities, the coal chemical industry into a resource-saving, environmentally friendly industry. The adoption of a high-efficiency, low-energy-consumption, low-pollution, low-emissions economic development approach based on environmental and resource affordability is the only acceptable sustainable development path for modern coal chemical industry. The carrying capacity of resources and environment is a constraint factor in the development of coal chemical industry. It can be said that the environmental protection issue of coal chemical industry is, in the final analysis, a problem of development methods.
Coal Chemical Industry promotes strategic structural adjustment and changes in development methods. It must strictly implement the national regulations on market entry thresholds such as energy consumption and environmental protection indicators; it must eliminate backward production capacity with high pollution and high consumption in accordance with the law; "High-grade capital" and excess capacity projects set "firewall."
Therefore, the chemical industry such as coal chemical industry should put environmental protection in a more important strategic position, enhance the sense of environmental awareness and do a good job of environmental protection legal consciousness, responsibility awareness. Correctly handle the relationship between environmental protection, economic development and social progress, implement protection in development, and promote development in protection. Among them, the development of coal chemical industry should strive to minimize pollution and energy consumption, and control the ecological, environmental, and resource capacity within the scope of carrying capacity. The development of coal chemical industry must not be at the expense of wasting resources, sacrificing the environment, and destroying the ecology. By earnestly drawing lessons from domestic and foreign developments and actively adjusting and controlling their own behaviors, we will build coal chemical industry into a socially responsible and trustworthy resource-saving and environment-friendly industry.
