Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a treatment device and a treatment method for industrial waste water. Background technique [0002] Industrial wastewater is an associated product of industrial production. It produces a large amount of industrial wastewater and contains a large amount of various organic pollutants and soluble salt impurities. Direct discharge will cause serious harm to the water body and the surrounding environment. It must be treated before it can be discharged or Reuse. Biochemical process is the most commonly used method to treat all kinds of industrial wastewater, which can effectively degrade various organic pollutants in wastewater, and the treatment cost is low. With the development of industrial technology and the increasing requirements of environmental protection, the requirements for various industrial wastewater treatment standards and reuse are getting higher a...
