An anaerobic biological treatment method for high-concentration organic wastewater

Abstract

The invention provides an anaerobic biological treatment method of high-concentration organic wastewater. The method implements anaerobe split-phase separation, and has the advantages of favorable granulation effect, high microbial biomass, high activity, high reactor load, high starting speed, and the like. The method can maximally reserve the high-activity sludge to form the optimal microbial community structure, thereby enhancing the biodegradability and achieving the goal of simultaneously decomposing organic matters and sludge.

Description

technical field

[0001] The invention relates to an anaerobic biological treatment method for high-concentration organic wastewater, which belongs to the field of organic wastewater treatment. Background technique

[0002] At present, in the field of high-concentration refractory organic wastewater and sewage treatment technology, because high-concentration refractory organic wastewater has the characteristics of high pollutant concentration, complex composition, high toxicity, and high salinity, the wastewater has poor biodegradability and is difficult to be decomposed by microorganisms. . Therefore, conventional wastewater treatment methods are difficult to purify or cannot meet the technical and economic requirements of this type of wastewater purification treatment. With the continuous development of modern environmentally friendly sewage treatment technology, the treatment of high-concentration organic wastewater is an urgent problem to be solved in the field of environ...
