Description
Technical field
The present invention relates to a kind of biological sewage treatment device, a kind of tower biological sewage treatment device particularly, 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 with opening between anaerobic reactor and aerobic reactor, wherein said opening has unidirectional by device, and this unidirectional material of flow lifting type sludge bed reactor that allows by device enters aerobic reactor and stops the material of aerobic reactor to enter the flow lifting type sludge bed reactor by described opening by described opening.
Background technology
Usually, the aerobe of sewage is processed can obtain good water quality, but needs large 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 usually relatively poor.Aerobic treatment and anaerobic treatment combination can be learnt from other's strong points to offset one's weaknesses.In sewage, but the material of most bio-oxidation can be converted into the methane consumption of energy and the mud increment reduces in anaerobic reactor, and remaining pollutent can be converted into 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 packaged unit, because the benefit of bringing can't compensate the investment of increase usually, also because required floor space is larger.With aerobic device and the anaerobic device layout that is perpendicular to one another, for example in same tower, 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 for collecting the plenum zone of methane bubble and the anaerobic reaction district between mixing zone and plenum zone at the top), and be arranged on the second section as aerobic reactor on up flow anaerobic sludge blanket reactor.One of defective of this device is that aerobic sludge and anaerobic sludge can mix in the zone of transition between two reactors.Due to the violent turbulence of fluid in 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.
US Patent No. 6,063,273 couples of WO96/23,735 disclosed biological sewage treatment devices improve, introduced the 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 arranged on above this buffer zone in 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 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 by opening.
The disclosed device of above-mentioned document does not all return to anaerobic reactor to the sewage in aerobic reactor and mud and controls.In some cases, for example the discharge of sewage is low when being even zero, the mud of aerobic zone may enter anaerobic zone uncontrollably, thereby wastewater treatment efficiency is caused disadvantageous effect.
Therefore, still need improved biological sewage treatment device to satisfy the various needs under different situations.For example, sewage and/or the mud of accurately controlling aerobic zone return to anaerobic reactor.
