| titleOfInvention | Enhanced sewage biological nitrogen and phosphorus removal method bases on polyhydroxyalkanoate metabolism regulation |
| abstract | The invention belongs to the field of environmental protection technology and relates to an enhanced sewage biological nitrogen and phosphorus removal method bases on polyhydroxyalkanoate metabolism regulation. The method comprises the following steps: introducing grain organic matters obtained after primary sedimentation and residual sludge discharged from a secondary sedimentation tank into a sludge tihckener for condensation; conducting anaerobic fermentation on the condensed organic refuses in a production reactor of a polyhydroxyalkanoate precursor to synthesize polyhydroxyalkanoate precursor; removing nitrogen and phosphor, and pumping the liquid into a pool for the polyhydroxyalkanoate precursor; pumping the polyhydroxyalkanoate precursor into a production reactor of polyhydroxyalkanoate to generate polyhydroxyalkanoate; and pumping the sewage into a routine sewage biological nitrogen and phosphorus removal reactor to carry out a sewage biological nitrogen and phosphorus removal process. The method provided by the invention can increase the removal rate of nitrogen and phosphor to 80% and 95%, and the treated outlet water reaches the sewage discharge standard Grade A. The method has advantages of convenient technology control, a small amount of generated greenhouse gas and sludge, and low cost of a reconstruction technology. |
