Abstract

The invention provides a treatment method for industrial wastewater. The treatment method solves the technical problems that the prior treatment technology steps are too complex, the treatment is tedious, and the like. The treatment method of industrial wastewater comprises the following steps: a, putting a precipitating agent in the industrial wastewater, and carrying out standing for 2-5 hours;b, filtering the industrial wastewater in the step a through a treatment device; and c, carrying out filtration and adsorption on the industrial wastewater in the step b through activated carbon to obtain treated industrial wastewater. The treatment method provided by the invention has the advantages of convenient treatment.

Description

technical field [0001] The invention relates to a treatment method, in particular to a treatment method for industrial waste water. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process lost with water. There are many types of industrial wastewater with complex components. For example, electrolytic salt industrial wastewater contains mercury, heavy metal smelting industrial wastewater contains various metals such as lead and cadmium, electroplating industrial wastewater contains various heavy metals such as cyanide and chromium, petroleum refining industrial wastewater contains phenol, and pesticide manufacturing industrial wastewater contains Contains various pesticides, etc. Because in...
