Problems solved by technology

Its main disadvantages are slow reaction speed, long reaction time, large volume of treatment structures, long start-up period, insufficient ability to deal with SS, and difficulty in forming granular sludge when treating high-concentration wastewater. However, these methods in the prior art It is difficult to treat high-concentration organic wastewater, and the treatment time is long, and it is difficult to form granular sludge. Therefore, a new technical solution is urgently needed to solve the technical problems existing in the existing technology

Abstract

The invention relates to a multi-phase reinforcement and guide type circular and anaerobic granulation reaction processing device applied to high concentrated organic wastewater. The processing device is characterized by comprising a water inlet assembly, a water outlet assembly, a processing device body, a biogas processing assembly and an internal circulation assembly, wherein the biogas processing assembly is arranged on the processing device body, and the internal circulation assembly is arranged in the processing device body; the water inlet assembly is arranged at the lower part of the processing device body, and the water outlet assembly is arranged at the upper part of the processing device body. The processing device has the beneficial effects that the integral structural design is skillful, and the operation is convenient; the rapid granulation of anaerobic sludge in the treatment process of high concentrated organic wastewater is realized by virtue of multiple granulated fillers, internal and external circulation, efficient water distribution and cyclic heating of wastewater, so that the anaerobic debugging time is shortened, meanwhile, the volumetric load and removal rate of an anaerobic reaction device for treating high concentrated organic wastewater are substantially improved, and the construction cost of the anaerobic reaction device is lowered.

Description

technical field [0001] The invention relates to a wastewater treatment device, in particular to a multi-phase enhanced separation and circulation anaerobic sludge granulation reaction device for high-concentration organic wastewater, which belongs to the technical field of sewage treatment. Background technique [0002] With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. High-concentration organic wastewater is a kind of industrial wastewater, with complex components and some toxicity. It is more difficult and more important than urban sewage treatment. The hazards of high-concentration organic wastewater produced by industry are mainly reflected in three aspects. One is aerobicity. Hazard: due to biodegradation, high-concentration organic wastewater will make the receiving water anoxic or even anaerobic, an...
