Problems solved by technology

[0002] The sewage generated in industrial production contains a variety of pollutants and emits an unpleasant temperature. In recent years, with the development of anaerobic technology, anaerobic reaction equipment is more and more used for industrial deodorization, but anaerobic reaction equipment High cost, high energy consumption, complicated equipment, difficult maintenance, and many pipelines need to be laid. If the content of hydrogen sulfide in the odor is high, the sulfuric acid produced by deodorization will destroy anaerobic microorganisms, reduce the deodorization efficiency, and greatly affect the enterprise. willingness to introduce
Enterprises usually recycle and use the treated clear liquid to clean the equipment used, but the washing efficiency is low, which reduces the use effect of the clear liquid. Therefore, it is necessary to develop a sewage treatment method to carry out multi-stage recycling of the treated clear liquid. , it has very important practical significance for the smooth progress of safe production, saving production costs and improving the production environment
