Spiral tube is provided with anoxic pond, water is flowed out from spiral tube outlet and the through hole spiraled on tube wall, in anoxic pond Agitating device need not be additionally installed, the water in anoxic pond can be formed from agitation formation and be circulated, and its stirring effect is uniform, Overcome and uneven defect is stirred using what stirring paddle stirring was caused, improve the clean effect of anoxic pond, and be more suitable for Combination type MBR membrane bioreactors continuously run.
Preferably, suspension-type combined filler is housed in biological contact oxidation pond, filler is at least by double annulars of two-layer Frame and tow groups are into the net being made into for cordage in the interior annular at filler center.The filler of biological contact oxidation pond is using light Matter, high-strength, anticorrosion, it is easy to the assembly that biofilm, specific surface area are big and voidage is high.Fibre bundle on suspension-type combined filler Be easier to allow microorganism to adhere to, substantial amounts of apposition growth place is provided for microorganism.
Preferably, curtain type film assembly by square outer edges frame with hang over tow groups therein into.
Preferably, aerating system is set below the membrane module, and is connected with electromagnetic air pump, air mass flow is by being located at Mass air flow sensor control on breather line, is conducive to increasing the cross-flow velocity on film surface.
A kind of combination type MBR membrane bioreactors of this utility model, its advantage is:
1) combination type MBR membrane bioreactors have good to the various contamination indexs such as COD, TOC, TN, TP and SS Removal effect, with good capacity of resisting impact load.
2) membrane module and inversion A 2/O, the combination of Biological Contact Oxidation Process, refer to denitrogenation dephosphorizing and the various pollutions of process Mark has reached good effect.
3) clearance of pollutant is different in the removal effect of different phase, and membrane bioreactor is to nitrogen, the removal master of phosphorus Will be in anoxic pond, anaerobic pond and Aerobic Pond;The efficiency that biological contact oxidation pond is removed to which is not high effectively can remove COD, TOC pollutant;Removal of the membrane module to SS is highly effective.
4) biological contact oxidation pond is set before membrane module, TOC is advantageously reduced, so as to reduces fouling membrane.Under membrane module Side arranges aerating system and is beneficial to increase the cross-flow velocity on film surface, and the two combination can increase membrane flux, ensure membrane bioreaction Answer the operation that device is steady in a long-term.
