Abstract
The invention discloses a gas expanded granular sludge bed anaerobic reactor. The reactor comprises an anaerobic reaction body (9), a water pump (6), a Venturi tube (5), a biogas circulation pipeline (8), a feeding tank (7), a discharging port (3), a gas outlet (2), a gas holder (1) and a sampling hole (4). According to the gas expanded granular sludge bed anaerobic reactor, sewage is sucked by the water pump (6), is mixed with biogas through the Venturi tube (5) and then enters the anaerobic reaction body (9) through jet, uniform distribution of gas and the liquid is realized, the circulated biogas amount can be controlled by controlling the external circulation pipeline (8), and the expansion degree of granular sludge in the reactor is controlled.
Description
Technical field
The present invention is the granular mud bed anaerobic reactor of a kind of gas expansion.
Background technology
The existing traditional reactor of anaerobic reactor had again modern high efficiency reactor, and anaerobic technique has developed into the multiple reactor types of the CGSB (EGSB and IC) of anaerobic filter (AF), anaerobic fluidized bed reactor (AFB), up-flow anaerobic sludge blanket (UASB) and the third generation of the second generation from the anaerobic digester of the initial first generation through the development of over one hundred year.
Traditional expanded granular sludge bed be mainly that the upflow velocity that utilizes water circulation and fermentation to produce biogas expands granule sludge, improve contacting between organic matter and microorganism in waste water, strengthen mass transfer effect, improve the biochemical reaction speed of reactor, thereby greatly improved the treatment effeciency of reactor. But in initial start stage because system COD volumetric loading is lower, gas production is less, after operation a period of time, easily there is compacting in Sludge Bed, and cause even piston flow phenomenon of channel, make inlet distribution inhomogeneous, easily in reaction zone, produce dead angle, in processing, when low concentration wastewater, also there will be above-mentioned phenomenon. Can cause like this mass-transfer efficiency of anaerobic sludge in dirty organic pollutants and reactor to reduce, make part anaerobe breeding accretion rate slow, reactor volume can not get effective utilization, thereby has reduced treatment effeciency.
Summary of the invention
The present invention, mainly for the problems referred to above, provides a kind of gas expansion granular mud bed anaerobic reactor, is mainly to utilize biogas recirculation to enter into reactor to carry out expanded granular sludge.
For achieving the above object, the present invention takes following technical proposals:

The granular mud bed anaerobic reactor of a kind of gas expansion of the present invention utilizes water pump (6) to draw sewage, make sewage and biogas mix jet afterwards by Venturi tube (5) and enter into reactor body (9), realized being uniformly distributed of gas and liquid simultaneously, and by controlling the biogas amount that external circulation line (8) can controlled circulation, control the degrees of expansion of the granule sludge in reactor simultaneously.
The described granular mud bed anaerobic reactor of a kind of gas expansion is further to utilize Venturi tube (5) to realize the even mixing of sewage and biogas, and jet enters reactor body (9) simultaneously, has realized being uniformly distributed of gas-liquid.
The described granular mud bed anaerobic reactor of a kind of gas expansion is further the principle of utilizing Venturi tube (5), in entering waste water extra absorption biogas granule sludge is expanded, saved the energy consumption of effluent recycling, saved operating cost.
The described granular mud bed anaerobic reactor of a kind of gas expansion is further to utilize biogas to pass through external circulation line (8) expanded granular sludge, effectively controls the degrees of expansion of granule sludge by the biogas amount of controlled circulation.
The beneficial effect that the present invention produces has: sewage during by Venturi tube extra absorption biogas granule sludge is expanded, save the energy consumption of effluent recycling, reduce the hydraulic load of reactor, and can effectively control the degrees of expansion of granule sludge. The present invention is not only applicable to EGSB reactor, is also applicable to IC, UASB reactor simultaneously.
