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,

Abstract

The invention belongs to the technical field of sewage processing, and more specifically relates to a multistage circulating-type sewage processing method. The multistage circulating-type sewage processing method comprises following steps: a pre-treatment tank is adopted for filtering, a deodorizing tank is adopted to adjust pH value to 6.5 to 7.5, a green tea extracted product is adopted for deodorizing, an internal circulation device is adopted to realize deodorizing tank internal circulation, an electrolysis tank is adopted to electrolysis removing of pollutants, a separation tank is adopted for filtering to obtain a clear liquid, the separation tank is connected with the electrolysis tank through a circulation pipe, and rotary washing of the electrolysis tank is adopted. The multistagecirculating-type sewage processing method is convenient for separation of solid garbage; the deodorizing mode is green, is friendly to the environment, and is capable of reducing economical cost; pipeline pavement is reduced; equipment internal circulation is adopted to promote deodorizing effect; external circulation among equipment is adopted to save water; and the utilization efficiency is high.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multistage circulating sewage treatment method. Background technique [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 ...
