摘要
在利用序批式生物膜法(SBBR)处理广州地区城市污水的试验过程中,研究了生物除磷效果及影响除磷的各种因素.试验结果表明:①磷的出水指标可以达到0.5 mg.L-1以下;②磷的厌氧释放是好氧吸收的前提条件;③溶解氧浓度影响磷的吸收速率,但不影响磷的去除总量;④生物膜的脱落是影响脱氮除磷的关键;⑤硝态氮并没有影响SBBR工艺除磷效果.
Effect and influenced factors of biological phosphorus removal is studied in the experiment that Guangzhou's municipal wastewater was treated by sequencing batch biofilm reactor (SBBR). The results showed that : Effluent target of phosphorus can be 0.5 mg · L^- 1 below ; The phosphorus release is the prerequisite of excess P-uptake ; DO influences only the rate of P-uptake, but not the total of P-removal ; Amount of sludge shedding from biofilm is the key factor of affecting nitrogen and phosphorus removal ; NO3-N doesnt inffluence the effcet of phosphorus removal.
