Abstract
An outer-circulation high-efficiency anaerobic reactor is characterized in that a reaction area is divided into a main reaction area and a secondary reaction area; a separation area is arranged at the upper part of the secondary reaction area and is communicated with a sedimentation tank; and the sedimentation tank is communicated with the main reaction area to form back flow. In the anaerobic reactor, the reaction area of an anaerobic expansion particle sludge bed is divided into the main reaction area and the secondary reaction area; and as the sectional area of the secondary reaction area is larger, and the ascending flow rate is small, the separation area is arranged at the upper part of the secondary reaction area, so that sludge and water are separated from each other for a short time and then enter the sedimentation tank to be deposited, and part of the sludge flows back. Therefore, the expansion effect of the main reaction area is improved, the efficiency for removing COD (chemical oxygen demand) is high, the loss of the sludge is reduced, the energy consumption is reduced, and the cost for sewage treatment is lowered.
Description
Technical field
The utility model relates to waste disposal plant, especially relates to a kind of device of disposing of sewage of efficient anaerobic.
Background technology
At third generation high efficiency anaerobic reactor (anaerobic expanded granular sludge bed) have the content of microorganisms height of unit volume, characteristics such as the hydraulic load that bears is big, floor space is little.When handling low-temperature and low-concentration organic waste water, the anaerobic expanded granular sludge bed very high current lift velocity relatively that in whole reactor, kept, and because the cohesive action of anaerobic reaction generation biogas makes the triphase separator place that quite high flow velocity be arranged.When fluctuation of operating conditions is big, the large number of biological body is run off, cause system's water outlet effect to descend.The prerequisite that system reaches high operating performance is that high current lift velocity will be arranged, and this needs a large amount of effluent recyclings to realize, will certainly strengthen running cost, is not very desirable from considering economically.
The utility model content
Technical problem to be solved in the utility model provides a kind of reaction unit of anerobic sowage efficiently, can obtain high clearance under reactor unit volume condition, has reduced the loss of reactor mud on the one hand; Increase the reaction zone volume on the other hand, saved energy consumption.
For solving the problems of the technologies described above, the utility model provides a kind of outer circulation high efficiency anaerobic reactor, it is characterized in that: reaction zone is divided into main reaction region and secondary response district, and top, secondary response district is the disengaging zone, the disengaging zone is communicated with settling tank, and settling tank is communicated with formation again and refluxes with main reaction region.
The utility model is divided into main reaction region and secondary response district with the reaction zone of anaerobic expanded granular sludge bed reactor, and the cross-sectional area of dimension reaction zone is bigger, and upflow velocity is little, so this reaction zone top is the disengaging zone, of short duration in after the mud-water separation, enter the settling tank precipitation, part mud refluxes.Strengthen the expansion effect of main reaction region like this, realized that high COD removes efficient, reduced the loss of mud, saved energy consumption simultaneously, reduced cost of sewage disposal.
Description of drawings
Accompanying drawing 1 is a structure principle chart of the present utility model.
Embodiment
With reference to accompanying drawing 1, reaction zone is divided into main reaction region 2 and secondary response district 3 according to 3: 2 ratios, top, secondary response district is disengaging zone 4, the disengaging zone is communicated with settling tank 7, settling tank is communicated with formation by backflow water pipe 5 and refluxes with main reaction region, the acidication bacterium is arranged in the main reaction region, and secondary response has methanogen in the district.
During work, sewage enters main reaction region by water inlet pipe 1, enter the secondary response district again, because the cross-sectional area in secondary response district is bigger, upflow velocity is little, so this reaction zone top is the disengaging zone, of short duration in after the mud-water separation, enter precipitation in the settling tank 7, part mud refluxes, constitute the outer circulation high efficiency anaerobic reactor, treated water is discharged by water shoot 6 and is utilized.
