CAFT efficient anaerobe reactor for treating sewage

Abstract

The invention discloses a CAFT efficient anaerobe reactor for treating sewage, which relates to sewage treating equipment. The CAFT efficient anaerobe reactor comprises a convection area, a suction area and a buffering area. The CAFT efficient anaerobe reactor is characterized in that: anaerobic microorganisms are placed in the convection area; a water distributor for inletting the sewage is arranged at the bottom of the convection area; a plurality of inclined tube settlers are slantways arranged on an upper part of the convection area; the suction area is in communicated connection with the upper part of the convection area; and fillers are placed in the suction area; the buffering area is arranged above the suction area; and a three-phase separator is arranged in the buffering area. The CAFT efficient anaerobe reactor for treating the sewage solves the problems of complicated structure of an anaerobe reactor, instability of a system, substandard water purification effect and high maintaining cost in the prior art, and the provided CAFT efficient anaerobe reactor has the characteristics of simple structure, low manufacturing and maintaining cost, and high removal rate of organic contaminants and the like. The CAFT efficient anaerobe reactor is mainly applied to treatment of wastewater with medium and high-concentration organic matters in brewage, starch processing, biological pharmacy, organic chemical industry, poultry farming, papermaking and the like.

Description

technical field [0001] The present invention relates to a sewage treatment equipment, in particular to an anaerobic bioreactor equipment which uses anaerobic microorganisms to treat organic pollutants in sewage. Anaerobic biological treatment uses the metabolic characteristics of anaerobic microorganisms without providing Under the condition of the source energy, the reduced organic matter is used as the hydrogen acceptor, and methane gas with energy value is produced at the same time. Background technique [0002] The most widely used anaerobic bioreactor in the world is the UASB anaerobic bioreactor. Such reactors are called second-generation anaerobic bioreactors. It is characterized by mature technology and easy manufacture. With the application of the fluidized reaction theory, the UASB reactor characterized by a relatively stable anaerobic biological bed shows the disadvantage of low reaction efficiency. And anaerobic expanded granular sludge bed (Expanded Granular ...
