Problems solved by technology

At present, there are many methods such as physics, chemistry, biology, and comprehensive methods to deal with the pollution of water resources, but most of the physical methods have problems of poor treatment effect and unstable treatment rate; the cost of biological methods is too high to be popularized and used; how to find a A sewage treatment agent with excellent performance and good stability to improve the treatment effect of industrial sewage has become a technical problem that needs to be solved at present
In particular, electroplating is one of the industries with serious pollution. Electroplating wastewater is rich in metal ions, such as Cu2+, Ni2+, Cr3+, Zn2+, Pb2+, Ag+, Cd2+, etc. If it is not recycled, it will cause waste of resources and seriously threaten people's health. Physical Health and Quality of Life
At present, the most widely used electroplating wastewater treatment technology at home and abroad is still the chemical precipitation method, but the treatment efficiency is low, the amount of sediment is large, and it is easy to cause secondary pollution.
