SBR法处理城市污水除磷效果及规律研究

Study on the law of phosphorus removal from municipal wastewater by Sequencing Batch Reactor (SBR)

介绍用SBR法 (序批式活性污泥法 )处理广州地区城市污水 ,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国家一级排放标准 ,去除率达 85 %～ 99% ;②污泥龄是影响脱氮除磷的关键 ;③磷的厌氧释放是好氧吸收的前提条件 .

Effect and influenced factors of biological phosphorus removal were studied in the experiment of treating Guangzhou's municipal wastewater by SBR. The results showed:(1)Effluent target of phosphorus can be 0.5 mg·L -1 below;(2)Sludge old is the key factor of affecting nitrogen and phosphorus removal;(3)The phosphorus release is the prerequisite of excess P-uptake.
