With the rapid development of the chemical industry, chemical wastewater has become one of the important factors affecting environmental quality. Chemical wastewater contains a large amount of toxic and harmful substances, such as heavy metals, organic pollutants, inorganic pollutants, etc., which pose a serious threat to the environment and human health. Therefore, it is of great significance to explore the relevant issues of chemical wastewater treatment.
Chemical wastewater mainly comes from the discharge of various links in the chemical production process, including raw material preparation, chemical reaction, product refining, by-product recovery, etc. In addition, the raw materials, catalysts, solvents, etc. used in the chemical production process may also have an impact on the wastewater.
Hazards of chemical wastewater
Toxic and harmful substances in chemical wastewater can have a serious impact on the environment. Specifically, they are:
(1) Destroy the habitat of aquatic organisms and affect fishery production;
(2) Pollute groundwater and endanger drinking water safety;
(3) Deposit in the soil and affect crop growth;
(4) Have a negative impact on human health, such as causing cancer and nervous system damage.
Chemical wastewater treatment technology
Physical method
Physical method refers to the method of treating chemical wastewater using physical principles and processes. Common technologies include gravity sedimentation, centrifugal separation, filtration, etc. These methods are mainly suitable for the removal of suspended matter, solid particles and other substances.
Chemical method
Chemical method is a method of treating chemical wastewater using chemical reactions and chemical agents. Common technologies include neutralization, oxidation-reduction, chemical precipitation, etc. These methods can effectively remove harmful substances in wastewater.
Biological method
Biological method is a method of treating chemical wastewater using the metabolism of microorganisms. Common technologies include activated sludge method, biofilm method, etc. These methods can effectively remove organic pollutants in wastewater.
Although my country's chemical wastewater treatment has made certain progress, there are still many problems and shortcomings. The main manifestations are that the treatment technology is not advanced enough, the operating cost is high, and the secondary pollution problem. In order to better solve these problems, relevant institutions and manufacturers should strengthen environmental awareness and research and innovation of treatment technology, improve the efficiency and quality of wastewater treatment, and protect people's health and environmental safety. At the same time, the government should increase its support for the chemical wastewater treatment industry, improve the construction and operation level of wastewater treatment facilities, and promote the sustainable development of the chemical industry.
