摘要
在利用序批式活性污泥法(SBR)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0.5mg/L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污泥龄是影响脱氮除磷的关键;⑤硝态氮并没有影响SBR工艺除磷效果.
Effect of and factors having influence on biological removal phosp horus were studied during the ex-perimental treatment of Guangzhou's urban wa stewater by SBR.The results showed that:①Effluent target of phosphorus can b e0.5mg /L below;②The phosphorus release is the prerequisite for excess P-u ptake;③DO influences only the rate of P-uptake,but not the total of P-remo val;④Sludge age is the key factor having ef-fect on nitrogen and phosphorus r emoval;⑤NO 3 -N does not inffluence the effcet of phosphorus removal.
