Comprehensive treatment method of high-concentration organic wastewater

Abstract

The invention relates to a comprehensive treatment method of high-concentration organic wastewater. SUN-SEP outlet water sequentially enters four separate pools of a BMS biological oxidation tank, and a filler and an efficient micro-aeration tube are arranged in each of the pools. The method comprises the following steps: SUN-SEP outlet water enters a fermentation pool, and more than 80 cultured microbe florae are used to reduce BOD and COD in water; water discharged from the fermentation pool enters a decomposition pool, and a liquid biological agent is used to cultivate strong strains and decompose and kill fermentation substances and harmful florae; water discharged from the decomposition pool enters a digestion pool, and culture cocci are conciliated to cannibalize and digest various corruptive substances and bacilli; and water discharged from a digestion pool enters a water discharge pool, and further undergoes aeration biological treatment, and finally obtained water is discharged.

Description

technical field [0001] The invention relates to a sewage treatment method, in particular to a comprehensive treatment method for high-concentration organic waste water containing high SS concentration. Background technique [0002] At present, the conventional treatment methods commonly used for high-concentration organic wastewater with high SS concentration are coagulation sedimentation or coagulation air flotation as the primary treatment, and anaerobic (facultative oxygen) and aerobic (AO) methods as the conventional secondary treatment. The existing problems of the treatment method are: (1) Primary treatment ① The solid-liquid separation method has mechanized equipment and low degree of integration, and the solid-liquid treatment effect and treatment method rely on physical methods to treat the effect generally. ②The power consumption and dosage of chemicals are large, and the effective utilization rate is low. (2) Secondary treatment ① The process is cumbersome and th...

Problems solved by technology

[0002] At present, the conventional treatment methods commonly used for high-concentration organic wastewater with high SS concentration are coagulation sedimentation or coagulation air flotation as the primary treatment, and anaerobic (facultative oxygen) and aerobic (AO) methods as the conventional secondary treatment. The existing problems in the treatment method are: (1) primary treatment ① The solid-liquid separation method has mechanized equipment, low degree of integration, and the solid-liquid treatment effect and treatment method rely on physical methods to treat the effect generally.

②Large power consumption and dosage of chemicals, low effective utilization rate

(2) Secondary treatment ① The process is cumbersome and the management is complicated; abnormal phenomena are prone to occur during operation, the sludge treatment volume is large, and the treatment system stays for a long time

②Large floor area, high investment and operating costs

③ There is a strange smell during the treatment process, and the environmental sanitation conditions are poor
