Problems solved by technology

[0003] However, in the prior art, biological or chemical multi-stage treatment methods are usually used to reduce the COD value of sewage. Due to the multi-stage treatment in this method, not only the volume of each stage of equipment is large, but also the structure is complex. The whole set of sewage treatment The equipment not only has low processing efficiency, but also has high cost, which is not conducive to the popularization and use of equipment

Abstract

The invention provides a circulating-type sewage treatment combined device. The device comprises an ozone contact-type circulating oxidation reactor and a circulating bioreactor, wherein the ozone contact-type circulating oxidation reactor is communicated with the circulating bioreactor. The device is simple in structure and small in size, has high efficiency and low cost for sewage treatment, and is convenient to popularize and apply.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to a circulating sewage treatment combined device. Background technique [0002] Industrial wastewater is the main factor causing water pollution in our country. Some wastewater in various industries has extremely high COD value but low deep material degradation, so it is difficult to meet the standard directly through biological aerobic or anaerobic treatment. For this kind of sewage, the more economical and effective process is to firstly oxidize the refractory organic matter in it by chemical method to improve its biodegradability and reduce the COD value. Among various oxidation methods, ozone contact oxidation has good effect and low cost, and is a commonly used sewage treatment method. [0003] However, in the prior art, biological or chemical multi-stage treatment methods are usually used to reduce the COD value of sewage. Due to the multi-stage treatment in this method,...
