Description
Technical field
The utility model relates to a kind of sewage disposal device, is specifically related to a kind of AAO-MBR integration denitrification and dephosphorization sewage disposal device.
Background technology
In municipal sewage, contain a large amount of nitrogen and phosphorus pollution materials, enter when sewage after the unhurried current water bodys such as lake, reservoir, river mouth, bay, nitrogen, phosphorus accumulate gradually, make particularly algal bloom of aquatile, finally cause water ecology balance to be seriously damaged, so-called eutrophication phenomenon occurs. Eutrophication not only can be destroyed the original ecosystem of water body, also can cause great economic loss to fishery, aquaculture etc., even jeopardizes human health when serious. In order effectively to contain body eutrophication, strict nitrogen, phosphorus discharge standard have been formulated in increasing countries and regions. But owing to there is the contradiction to carbon source demand in traditional sewage treatment process, water outlet nitrogen, phosphorus concentration are difficult to simultaneously up to standard between denitrogenation and dephosphorization, and this makes sewage denitrification and dephosphorization become focus and the difficult point of sewage treatment area.
MBR is a kind of by membrane separation technique and the combined Novel sewage treatment and reuse technique of biological processing unit. This technique is owing to adopting efficient film to separate the second pond substituting in conventional activated sludge process, and solid-liquid separation efficiency is high, and water outlet is good and stablize, can direct reuse; In reactor, can keep the microbial biomass of high concentration, processing volume load is high, small accommodation area; Excess sludge generation is little; Convenient operation and management, automaticity is high. In view of the advantage of MBR, set up MBR sewage disposal and the wsates resources project of considerable scale and quantity both at home and abroad. MBR, owing to moving under high sludge concentration, therefore can improve the disposal ability of system, but it is unfavorable to film pollution control to cross high sludge concentration, needs higher aeration energy consumption carry out controlling diaphragm and pollutes.
Sewage denitrification and dephosphorization and reduction system operation energy consumption are important applied field and the developing direction of MBR, and due to complicated mechanism, influence factor is numerous, and the denitrogenation dephosphorizing of the most independent investigation MBR of existing research or energy-saving and cost-reducing, is difficult to both and takes into account. Part Study adopts the mode of additional carbon to improve Nitrogen/Phosphorus Removal simultaneously, but owing to having increased complexity and the operating cost of technique, is not suitable for large-scale promotion. Have research by application A2O technique denitrification dephosphorization technology, make denitrogenation and dephosphorization can share a part of carbon source, can alleviate to a certain extent both contradiction, but its effect is still limited, in the time of reply low carbon-nitrogen ratio sewage, denitrification effect is undesirable. Also have the endogenous denitrification technology of employing, utilize the intracellular organic matter of microorganism as carbon source, without the carbon source in sewage, thereby be highly suitable for the denitrogenation dephosphorizing processing of the limited municipal sewage of common carbon source content, this technical stability also needs to optimize. Energy-conservation aspect mainly reaches energy-saving and cost-reducing object with optimization film group device structure, the more efficient aeration mode of exploitation.
