In MBBR ponds 2, aeration rate is 50～80l/h, and PH is 6.5～7.5, and hydraulic detention time is 2～8h, and temperature is 15
～25 DEG C.In carbon source adding set 8, addition methanol is carbon source.
The key factor for affecting MBBR synchronous nitration and denitrifications is dissolved oxygen (DO) concentration, carbon-nitrogen ratio (C/N), biomembrane
Thickness, acid-base value and temperature.
DO is carried out and is controlled, aerobic zone and anoxic zone, the increase of DO concentration can be formed in biomembranous different parts simultaneously
Be conducive to nitration reaction to carry out, but denitrification rate can be suppressed, therefore carbonaceous organic material oxidation, nitrification and denitrification will be realized,
Need to keep appropriate DO levels, and then denitrification effect can be improved, the energy needed for aeration can be saved again, this utility model leads to
Cross control aeration rate to control DO concentration, make DO concentration be maintained at proper level.
Organic carbon source sewage biological denitrificaion process in play an important role, it be bacterial metabolism necessary to material and
Energy is originated, and fully, C/N is high so that the assimilation of nitrifier is dominant and is unfavorable for ammonia nitrogen removal for organic carbon source；Machine carbon source contains
Amount is too low, then can not meet denitrifying needs, and this utility model is carbon source so that C/N is maintained at appropriate water by extraneous methanol
It is flat.
In MBBR ponds 2, on certain thickness biomembrane, nitrification and denitrification can be carried out simultaneously, because oxygen can only be penetrated into
The a certain depth of filler outer layer, i.e. outer layer are that aerobic layer occurs nitration reaction, and internal layer is that anoxic layer occurs anti-nitration reaction, Jing sheets
Experiment repeatedly proves that the biofilm thickness of filler is suitable for 300～400um.
In this utility model MBBR ponds 2, simultaneous nitrification and denitrification course of reaction yet receives acid-base value, temperature, hydraulic retention
Time and the impact of media-filling rate, this utility model above-mentioned parameter proved through many experiments, has obtained optimum ginseng
Scope is counted, simultaneous nitrification and denitrification can be realized well within this range.
Sludge reflux pump 10 in intermediate sedimentation pond 3 is connected with MBBR ponds 2 by sludge pipe；In second pond 6
