How can polypropylene be a "top priority" environmental issue
In the period of economic growth shift, environmental protection has been paid more and more attention by the country, GDP growth has entered the medium and high-speed development channel, the momentum of rapid development of heavy chemical industry has slowed down, the tertiary industry has become the main driver of economic growth, and the total volume and structure are developing in the direction of favorable environmental protection. The polypropylene industry is also facing greater challenges in the face of environmental protection issues.
"The Basic Ideas of the 13th Five-Year Plan for National Environmental Protection" has been compiled, and two phased goals for 2020 and 2030 have been initially proposed. During the "13th Five-Year Plan" period, a dual system of environmental quality improvement and total pollutant control will be established, and air, water, and soil pollution prevention and control plans will be implemented to achieve the management of the three ecosystems' total factor indicators; On the basis of the total amount control of existing conventional pollutants, the total amount control of new pollutants should focus on specific regions and industries; Air quality will be managed according to different areas and categories, and cities with PM2.5 levels within 30 percent of the standard are expected to be the first to reach the standard by 2020."
Eastern region: The task of haze control is severe, and some downstream enterprises are affected
According to the "basic ideas", in the 12 provinces in eastern and central China with serious PM2.5 and significant air pollution transmission impact, the Pearl River Delta, Chengdu-Chongqing region, the environmental protection problems of downstream enterprises of polypropylene manufacturers have gradually been paid attention to, especially in the heavily polluted Beijing-Tianjin-Hebei region, under the haze in December 2016, Shijiazhuang has the most severe haze for 45 days.
Northwest region: coal chemical world wastewater treatment priority
Because of the rich coal in northwest China, the development of polypropylene is mainly concentrated here. Coal chemical wastewater pollution is relatively serious, if it is not strictly treated, it will cause serious environmental pollution, which is not consistent with the environmental protection idea vigorously advocated by our country. Therefore, at the same time of coal chemical production, coal chemical wastewater treatment technology should be scientifically and reasonably applied to treat coal chemical wastewater, so that wastewater discharge can meet the discharge standards, so that more economic benefits can be created at the same time, protect the environment. Coal chemical industry uses coal as fuel through chemical processing to transform coal and comprehensively utilize it into industry, so a large amount of oil and natural gas are needed in daily coal chemical production. But coal chemical production process will discharge a lot of waste water, if the waste water treatment is not good will seriously affect the development of coal chemical industry, and in fact also confirmed this situation. In this regard, China's coal chemical enterprises should deeply study the treatment technology of coal chemical wastewater, and then rationally use this technology to treat coal chemical wastewater, improve the utilization rate of resources, and avoid environmental pollution. Therefore, the effective application of coal chemical wastewater treatment technology is very meaningful.
In the case of polypropylene expansion, environmental protection issues will be paid more attention to, and the development of more environmental protection will be an important basis for the development of polypropylene industry.
