Although China's chemical water pollution prevention and control has made continuous progress in recent years, the chemical industry is still a frequent area of â€‹â€‹water pollution accidents. On April 16, the Water Pollution Prevention and Control Action Plan, known as the "Water Ten Article," was formally released. Many articles involved the chemical industry, and there was one more "constraint" in chemical water pollution control. This will force enterprises to comprehensively control pollutant emissions, promote economic restructuring and upgrading, and strive to save and protect water resources, thereby improving the image of the chemical industry.
From the "Water Ten Articles" section, it is not difficult for us to find that there are many chemical industries involved and we have concluded that there are three key points. The first is to ban "small chemicals." Before the end of 2016, all production projects that do not meet the national industrial policies, such as small-scale printing and dyeing, dyes, coke making, refining, arsenic refining, oil refining, and pesticides, will be banned. The second is the special rectification coking, nitrogen fertilizer, printing and dyeing, raw material drug manufacturing, pesticides and other industries, implementation of clean transformation. The newly-built, rebuilt or expanded construction projects of the above-mentioned industries shall be subject to equal or reduced replacement of major pollutants. Before the end of 2017, the urea production in the nitrogen fertilizer industry was completed by the technical hydrolysis reformation of the condensate. The third is to promote economic restructuring and upgrading. Strengthen industrial water recycling, wastewater treatment and reuse of high-water-consuming enterprises such as petroleum, petrochemical and chemical industries; optimize spatial layout, and strictly control petroleum processing, chemical raw materials and chemical product manufacturing, pharmaceutical manufacturing, chemical fiber manufacturing, etc. Project environmental risks, reasonable layout of production facilities and storage of hazardous chemicals and other facilities.
The system is in place. If it is not implemented, there will be more papers than papers. The best system is also furnishings. Therefore, the key to chemical treatment of water pollution is the implementation of the system.
In order to promote the implementation of the "Water Ten Articles," we must first implement the responsibilities of various departments at the national and local levels, strengthen supervision, and prevent them from escalating into forms, pushing each other, and not engaging each other. The â€œWater Ten Articlesâ€ were detailed, and more than 200 specific control measures were put forward. Each measure has quantitative indicators. It also confirms the period of governance and the corresponding responsible department. However, most of the chemical companies in China are located along the river and the sources of water pollution are relatively complex. Not only do they involve many management departments, but also the distribution of authority and power of many institutions is not clear. Therefore, it is necessary to implement the concept of pollution control at the source to further clarify the authority and strengthen supervision.
Secondly, it is necessary to implement scientific and technological input from the government and enterprises and improve the environmental protection level of the technology and equipment. In fact, China's chemical industry has not really realized the recycling of water resources, and there are not many companies that have zero emission or discharge standards, and industrial upgrades and environmental protection technological transformations have been awaited. "Water Ten" requires strengthening of scientific and technological support, promotion of applicable technologies, and research and development of forward-looking technologies. The implementation of this clause requires that the state increase the support for special funds for science and technology, and at the same time use the preferential policies of finance and taxation to support it. In this way, we can realize the goal of encouraging enterprises to increase investment and improve the level of independent environmental protection technology innovation, and promote the adjustment and upgrading of the chemical industry structure.
In addition, public participation and social supervision must also be implemented. One of the highlights of the â€œWater Tenâ€ is the requirement for information disclosure and public supervision, and the public participation and complaint reporting system has been clarified. To achieve this, on the one hand, government departments must adhere to the administration according to law, increase transparency, and allow power to operate under the sun. On the other hand, the public must actively strengthen environmental protection awareness and actively participate in environmental governance.
In the long run, "Water Ten" will surely give the polluting companies a "sweeping spell" to form a new mechanism for water pollution control that is government-led, corporate governance, market-driven, and public-participated to achieve environmental, economic, and social benefits. Multi-win.
Geonet can be used as a kind of filling layers for stabilization, detritus separation, horizontal drainage cushion, underwater drainage constructure and slope road protection structure in building roads, railway, ports, airports, mining, hydro-power engineering projects.
1. It reinforce old asphalt concrete road surface and asphalt layer, and prevents damage ;
2. It is used for rebuilding cement concrete road surface into composite road surface and restraining reflection caused by block contraction .
3. It is used in road expansion and improvment project and crack caused by old and new combination position and uneven sedimentation ;
4. It is used in soft soil base reinforcement treatment , is favorable for soft soil water separation and concretion,restrains sedimentation effectivly,distributes stress uniformly and improve overall strength of road base;
5. It is sued for preventing contraction crack caused by new road semi-rigid base layer,and reinforces and prevents road surface crack caused by foundation crack reflection.
