| 摘 要： | 研究了A2/O与悬浮填料生物膜(SCBP)中试复合工艺的除磷效率,并考察了影响因子COD/TP与DO对除磷的影响。结果表明:总磷平均去除率为82%,达到GB/T18921-2002景观用水水质要求。当硝酸盐含量急剧下降至0.20mg/L以下时,反硝化除磷菌不再以硝酸盐作为电子受体进行聚磷活动,厌氧磷释放的最佳碳磷比为60。添加纳米改性的悬浮填料后,好氧池的溶解氧为2.0mg/L时,出水TP为0.3～0.35mg/L。

| Abstract: | Combined process of A2/O and suspended carrier biofilm process (SCBP) in pilot scale was used to enhance phosphorus removal. Effects of COD/TP ratio and dissolved oxygen (DO) on phosphorus removal were investigated. The results indicate that the average TP removal rate is 82% during the 180 d operation, which meet the requirement of GB/T18921-2002. Nitrate is no more used as an electron acceptor by denitrifying phosphorus removal bacteria (DPB) when NO3-N concentration decreases to lower than 0.20 mg/L in this test. The optimal COD/TP ratio is 60 for this test. Due to the addition of modified suspended carrier by nanotechnology, effluent TP concentration reaches 0.3~0.35 mg/L when the DO concentration in aerobic tank is 2.0 mg/L. |
