The lack of effective and applicable technology is a major bottleneck in the environmental development of the petroleum and chemical industries. In order to break through this bottleneck, it is necessary to accelerate the establishment of a “green technology†system including environmental engineering technology, waste resource technology, and clean production technology. This is the information that the reporter obtained from the exchange meeting on new technologies, new products and new equipment for environmental protection in the petroleum and chemical industry that ended on June 23.
According to the China Petroleum and Chemical Industry Association, at present, many areas of the petroleum and chemical industry still lack effective energy-saving and emission-reduction advanced technologies, especially high-concentration salt-containing organic wastewater, organic waste gas and hazardous waste treatment technologies. Technical backwardness is a major bottleneck in the development of environmental protection. Without breakthroughs in advanced applicable technologies, it is impossible to make major breakthroughs in energy conservation and emission reduction and industry development. At the same time, the petroleum and chemical industries have become the focus of national pollution control. Among the national key monitoring enterprises identified by the State Environmental Protection Administration, there are 3,952 exhaust gas pollution sources and 3,115 wastewater pollution sources, including 482 exhaust gas pollution sources and 803 wastewater pollution sources in the petroleum and chemical industries.
The reporter learned that due to the lack of economical and reliable environmental protection technology, some enterprises want to cure pollution, but there is no way to achieve it. For example, in the production of pesticides such as pesticides, fungicides and herbicides, the chemical oxygen demand in the discharged wastewater is as high as several thousand to tens of thousands of milligrams per liter; the dyes and pigments have a wide variety of pollutants and complex components. The water quality and water quantity vary widely, the concentration is high, the biodegradability is poor, and the treatment is very difficult. The company reflects that it hopes that there will be more environmental technologies and products that can solve practical problems.
According to the China Petroleum and Chemical Industry Association, in order to break through the bottleneck of environmental protection technology as soon as possible, during the “Eleventh Five-Year Plan†period, China’s petroleum and chemical industry will increase efforts to tackle key technologies of resource conservation and recycling, and prioritize the development of refining, ammonia, and sulfuric acid. , caustic soda, calcium carbide, pesticides, dyes, coatings, inorganic salts, etc., large production volume, large number of enterprises, wide distribution and serious pollution of clean chemical production technology and waste recycling technology; organic raw materials, pesticides, dyes, some fine chemicals Reduction technologies for refractory organic pollutants such as aromatic hydrocarbons, halogenated alkanes, and organosulfur compounds emitted by the industry; source reduction technology for ammonia nitrogen wastewater; thickening technology for producing dilute waste sulfuric acid from dyes and titanium dioxide; chromium slag and phosphogypsum Slag, calcium carbide slag comprehensive utilization technology.
