| 摘 要： | 采用序批式生物膜工艺进行了处理广州地区城市污水的脱氮除磷试验研究，结果表明：在碳、氮、磷比例失调（碳量偏低）的情况下，达到了既去除有机物又能脱氮除磷的效果，出水BOD5、COD分别为6．0～9．8、12．7～35．5mg／L，而TN、NH3-N、TP分别在14．8、4．0、0．5mg／L以下；磷的厌氧释放是好氧吸磷和除磷的前提；DO浓度会影响好氧段的磷吸收速率，但不影响磷的去除量；在好氧运行初期发生了同步硝化反硝化，其去除的总氮约为15％。

| Abstract: | A study was made on nitrogen and phosphorus removal from municipal wastewater in Guangzhou City by Sequencing Batch Biofilm Reactor(SBBR) process.The results show that at undesirable proportion of C,N and P,removal of both organic matters and N-P can be achieved.The concentration of effluent BOD_5,COD is 6.0-9.8 mg/L,12.7-35.5 mg/L respectively;that of TN,NH_3-N and TP is under 14.8,4.0,0.5 mg/L respectively.Phosphorus release is the necessary condition of phosphorus uptake and phosphorus removal.Though DO can probably affect the rate of phosphorus uptake,it doesn't affect the amount of phosphorus removal.At the initial stage of aeration,simultaneous nitrification and denitrification(SND) takes place,which can remove TN by 15%. |
