Description
Technical field
The present invention relates to the environmental sanitation field, specifically is a kind of efficient anaerobe reactor.
Background technology
The anaerobe reaction technology is under anaerobic, has formed needed nutritional condition of anaerobion and envrionment conditions, utilizes this quasi-microorganism metabolism, decomposes the organism in the waste water and produces methane and the process of carbonic acid gas.
Common anaerobic biological reactor mainly contains three types: the first kind is representative with the anaerobic pond that generally uses, and reaction tank appears fully and mixes, and does not have the mud circulation, and it is low to handle load, and processing efficiency is low.Second type is upflow anaerobic sludge blanket process (UASB), and it mainly is made up of sludge reaction district, gas-liquid-solid three-phase separator, and UASB retains a large amount of anaerobic sludges in the reaction zone of bottom; Mud with good sedimentation function and cohesion performance forms sludge blanket in the bottom; The mud that is precipitated on the skew wall is slided back in the anaerobic reaction district along skew wall, makes a large amount of mud of accumulation in the reaction zone, overflows on overflow weir top from the settling region with the treat effluent after mud separates; Discharge Sludge Bed then; Be characterized in being provided with gas-liquid-solid three-phase separator, processing efficiency is high, but mud often runs off.The 3rd type is representative with anaerobic grain sludge expanded bed (EGSB) and anaerobism inner circulation reactor (IC); Be characterized in alleviating the UASB reactor drum defective of short stream easily; Yet the EGSB reactor drum needs liquid return, and power consumption increases; Water quality treatment is difficult to further raising, and IC reactor drum operation ratio is difficulty.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, handle through subregion when the organism in decomposing waste water is provided, have good processing efficiency, and easy to operate, stable a kind of efficient anaerobe reactor.
The object of the invention is mainly realized through following technical scheme: a kind of efficient anaerobe reactor; Comprise reactor body, flashback tank and vapor pipe; Said reactor body inside constitutes muddy water mixing zone, suspension zone, three-phase separation area, settling region and air chamber from the bottom to top; Muddy water mixing zone, suspension zone, three-phase separation area and settling region are connected in order, and the reactor body outer side wall is connected with water inlet pipe, rising pipe and shore pipe, and said water inlet pipe is connected the muddy water mixing zone; Rising pipe is connected the settling region, and shore pipe is connected the suspension zone; Said flashback tank is arranged on the top of reactor body and connects air chamber, is provided with the triphase separator that is connected with vapor pipe in the said three-phase separation area, and triphase separator is connected flashback tank through vapor pipe.
The corresponding reactor body sidewall of said muddy water mixing zone, suspension zone and settling region three all constitutes cylindric; The corresponding reactor body sidewall of said three-phase separation area constitutes the sidewall shape of the inverted frustum of a cone, and the reactor body sidewall that said air chamber is corresponding constitutes the sidewall shape of the frustum of a cone.The present invention is when work, and after the sewage upper reaches was passed through muddy water mixing zone, suspension zone successively, because enlarged areas, flow velocity reduced, and so, is convenient to the muddy water precipitate and separate.
