Higher is required to N, P, simple technique can not meet the requirement of high standard, and various techniques are only made up by group technology
The defects of.
3rd, MBR methods are that now current effluent quality preferably runs most stable of technique, but because its initial investment is higher, later stage dimension
It is higher to protect operating cost, is implemented with certain economic limitations.
4th, by changing the fixation filler in Aerobic Pond as flowing filler, reached by filler friction, flowing etc. has MBBR
Machine matter is degraded and old biomembrane comes off.The organic loading of system is effectively increased, now typically uses pre- denitration+A2O at present
Process combination can preferably remove the organic matter in waste water, because filler flowing wear rate and turnover rate are higher.
Utility model content
The purpose of this utility model is：For problems of the prior art, there is provided a kind of sanitary wastewater processing one
Body equipment, by playing the effect of existing activated sludge, traditional practical A2O activated sludge process is combined with MBR films, saved
