This reactor is owing to adopt biomembrane process mode (being that floating stuffing is set in the pond), and reactor has higher microorganism concn, and anti impulsion load and adaptability are strong; By combined stuffing is set in biological treatment tank, and the suitable dissolved oxygen levels of control, can form aerobic and anoxic microenvironment in that microbial film is inner, be easy to realize synchronous nitration denitrification denitrogenation efficiently.Simultaneously, reactor adopts the sequence batch (operation, and can realize aerobic-anoxic anaerobism alternate run by intermittent aeration in reaction tank, for the microbial film dephosphorization has made up good environment.In addition, handle the further dephosphorization denitrogenation of microorganism, waterplant that in artificial wet land system, utilizes on the rich calcium matrix of rich iron, the matrix by ecological cooperative, and the filteration by the wetland hypothallus, guaranteed that reactor obtains high processing usefulness and stable water flow quality.
2. flexible operation, energy consumption is low
Usually the energy consumption cost in the sewage treatment process accounts for the large percentage of its running cost, and cutting down the consumption of energy is the key point that reduces running cost.The energy consumption of general sewage treatment process is mainly used in lifting, aeration and the nitrification liquid of sewage and the backflow of mud.This reactor can be realized synchronous nitration and denitrification efficiently by floating stuffing is set in biological tank, saved the mixed-liquor return system.Simultaneously, adopt the sequence batch (operation scheme and in reaction tank, realize aerobic-anoxic anaerobism alternate run,, saved the mud return-flow system of general dephosphorization system for the biomembrance process efficient dephosphorization has made up good environment by the control aeration mode.And, adopt biomembrance process to make up this treatment system, saved general reactor required whipping appts in anaerobic phosphorus release and anoxic denitrification process.In addition, adopt the ecological cooperative processing of no energy consumption further to promote treatment efficiency, also provide guarantee for effluent quality stable.And,, can realize that biological treatment is auxilliary, further reduces operation energy consumption by operating mode adjustment based on Ecological Disposal to biological tank and ecological pool in temperature high season.Therefore this reactor has efficient feature.
3. surplus sludge volume is few
Floating stuffing is set in biological treatment tank forms the stable complex ecosystem of forming by a plurality of trophic levels, reduced sludge yield.On the other hand, the ecological cooperative treating part produces excess sludge hardly.
4. technical process weak point, integrated design, occupation of land less, the investment low
The adjusting of this reactor collecting water from runoff, organic matter removal, biological dephosphorize denitrification, mud decrement, precipitation and technique units such as Ecological Disposal and sterilization are one, particularly utilize reactor wall altogether, air blast machine room and biological treatment tank are built into one, Ecological Disposal unit and biological treatment tank and sterilization pool are built into one, have significantly reduced the investment and the occupation of land of reactor.Inlet and outlet water can be adopted intermittent flow and many sets in parallel operation, has the flexible characteristics of operational administrative.
5. collect biological and ecological and be treated to one, landscape effect is good
