Description
Technical field
The utility model relates to a kind of biological sewage treatment device, particularly a kind of tower biological sewage treatment device, comprise anaerobic reactor in the tower bottom, at the aerobic reactor at tower middle part, at the separator on tower top and the dividing plate between anaerobic reactor and aerobic reactor with opening, wherein be provided with outstanding aerobic sludge receiving tank downwards at the edge of dividing plate, this aerobic sludge receiving tank is communicated with the aerobic reactor fluid.
Background technology
Usually, the aerobe of sewage is handled can obtain good water quality, but needs big energy to carry out aeration and can produce a large amount of solid mud.The anaerobic biological treatment power consumption of sewage does not produce extra mud less and substantially, but the water quality that obtains is relatively poor usually.Aerobic treatment and anaerobic treatment combination then can be learnt from other's strong points to offset one's weaknesses.But the material of most bio-oxidation can be converted into the methane consumption of energy and the mud increment reduces in the sewage in anaerobic reactor, and remaining pollutent can be converted into the biomass and the carbonic anhydride (carbonic acid gas) of sludge form in aerobic reactor.Being combined on some large-scale plants of aerobic treatment and anaerobic treatment is particularly suitable.Yet such being combined in lacks magnetism usually in the packaged unit, because the benefit of bringing can't compensate the investment of increase usually, also because required floor space is bigger.With aerobic device and the anaerobic device layout that is perpendicular to one another, for example in same tower, then make the combination of aerobic treatment and anaerobic treatment also can be suitable for packaged unit.
International Patent Application WO 96/23,735 disclose a kind of biological sewage treatment device, comprise as upflow anaerobic sludge blanket process (upflow anaerobic sludge blanket, UASB) first part of reactor (described first part comprises mixing zone in the bottom, is used to collect the plenum zone of methane bubble and the anaerobic reaction district between mixing zone and plenum zone at the top) and be installed in second section on the up flow anaerobic sludge blanket reactor as aerobic reactor.One of defective of this device is that aerobic sludge and anaerobic sludge can mix in the zone of transition between two reactors.Because the violent turbulence of fluid in the aerobic reactor, anaerobic sludge possibly can't sink to returning anaerobic reactor.Simultaneously, when the sewage feed rate was low, aerobic sludge also may be settled down to anaerobic reactor.These all may have a negative impact to wastewater treatment efficiency.
U.S. Pat 6,063,273 couples of WO96/23,735 disclosed biological sewage treatment devices improve, introduced third part as the anaerobic sludge buffer zone, the top of this buffer zone is limited by the dividing plate with opening, and the bottom is limited by gas collector, provides the air feeder of air/oxygen to be installed in this buffer zone top in the aerobic reactor.Described dividing plate makes anaerobic sludge be difficult to enter aerobic reactor, also makes aerobic sludge be difficult to enter anaerobic reactor, and the anaerobism effluent liquid then can enter aerobic reactor by the opening of described dividing plate.In comparatively tranquil buffer zone, anaerobic sludge can sink to returning anaerobic reactor.Yet, when the sewage feed rate lower or the time, aerobic sludge still may enter anaerobic reactor uncontrollably by opening.
The disclosed device of above-mentioned document all is difficult to effectively the aerobic sludge in the aerobic reactor be concentrated and precipitate, and also is difficult to control aerobic sludge effectively and is back to anaerobic zone.Therefore, still need improved biological sewage treatment device with dealing with various requirements.
