Abstract

The invention provides a double-MBR- method sewage treatment process combined with ozone oxidation. The process comprises the steps of pretreatment, biochemical treatment, primary MBR method treatment, ozone oxidation treatment, secondary MBR method treatment and filtration to obtain water meeting the emission standard, the process can reduce the addition amount of conventional ozone, reduce the generation of sludge, improve the degradation rate of degradation-resistant substances, has a wide application range and has process practicability.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a double MBR sewage treatment process combined with ozone oxidation. [0002] technical background [0003] In recent years, with the rapid development of industry, the types and output of organic compounds have also been increasing. The discharge of various industrial wastewater continues to threaten water bodies. The deterioration of water sources is becoming more and more extensive and serious. The protection of water resources is imminent. [0004] MBR (Membrane Bio-Reactor, membrane bioreactor) technology is a new type of water treatment technology. It combines the traditional activated sludge method with membrane separation technology, relying on the latter's high-efficiency solid-liquid separation to replace the secondary settling tank in the traditional process, realize the separation of mud and water, and also replace the advanced treatment process after the secondary sett...
