The lack of effective and applicable technologies is a major bottleneck for the environmental protection of the petroleum and chemical industries. In order to overcome this bottleneck, we must speed up the establishment of a "green technology" system that includes environmental engineering technologies, waste resource technologies, and cleaner production technologies. This is the information that the reporter obtained from the exchange of new technologies, new products, and new equipment for environmental protection in the petroleum and chemical industries that ended on June 23.
According to the China Petroleum and Chemical Industry Association, at present, many fields in the petroleum and chemical industries are still lacking effective technologies for energy-saving and emission-reduction, especially high-concentration salt-containing organic wastewater, organic waste gas and hazardous waste treatment technologies. Technological backwardness is a major bottleneck for environmental protection development. Without the breakthrough of advanced and applicable technologies, it is impossible to make major breakthroughs in energy conservation and emission reduction and industrial development. At the same time, the petroleum and chemical industries have become the focus of national pollution control. Among the key state-monitored enterprises identified by the State Environmental Protection Administration, there are 3,592 waste gas pollution sources and 3115 waste water pollution sources, of which 482 are waste gas pollution sources in the petroleum and chemical industries and 803 are waste water pollution sources.
The reporter learned that due to the lack of economical, reasonable and reliable environmental protection technologies, some companies want to treat pollution, but there is no way to achieve it. For example, in the production of pesticides, fungicides, herbicides and other crude drug species, the chemical oxygen demand in the discharged wastewater is as high as several thousands to tens of thousands of milligrams per litre; dyes and pigments have a wide variety of waste water pollutants and the components are complex. , Water quality, water volume range, high concentration, poor biodegradability, handling is very difficult. The company reflects on the expectation that there will be more environmentally friendly 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 “11th Five-Year Plan†period, China’s petroleum and chemical industry will increase its efforts in key technologies for resource conservation and recycling, and give priority to the development of oil refining, ammonia synthesis, and sulfuric acid. , caustic soda, calcium carbide, pesticides, dyes, paints, inorganic salts, etc. Large-scale chemical product clean production technology and waste recycling technology with large production volume, large number of enterprises, wide distribution and serious pollution; organic raw materials, pesticides, dyes, and some fine chemicals Reduction technologies for waste water containing refractory organic pollutants such as aromatic hydrocarbons, halogenated alkanes and organophosphorous compounds discharged from other industries; reduction of ammonia nitrogen at the source of wastewater; technologies for the production of dilute waste sulfuric acid from dyes and titanium dioxide; chromium slag and phosphogypsum Slag, calcium carbide slag comprehensive utilization technology.
