Industrial wastewater includes production wastewater, production wastewater, and cooling water. It refers to the wastewater and waste liquid generated during the industrial production process, which contains industrial production materials, intermediate products, by-products, and pollutants generated during the production process that are lost with water. Industrial wastewater varies in type and composition depending on the nature of the production enterprise. Generally, the emission standards can be achieved through the treatment process of "pretreatment+biochemical treatment+deep treatment".

Generally, the emission standards can be achieved through the treatment process of "pretreatment+biochemical treatment+deep treatment".
According to the different properties of industrial wastewater, pretreatment can include treatment processes such as grid, oil separation, air flotation, coagulation and sedimentation; Biochemical treatment can include treatment processes such as A, O, etc; Deep processing can include treatment processes such as air flotation, multi-media filtration, advanced oxidation, etc;
According to emission standards and industry standards, it can be treated to meet comprehensive sewage discharge standards, reuse standards, or surface discharge standards.
