A2/O與SCBP復(fù)合工藝除磷中試研究

摘要: 研究了A2/O與懸浮填料生物膜(SCBP)中試復(fù)合工藝的除磷效率,并考察了影響因子COD/TP與DO對除磷的影響.結(jié)果表明:總磷平均去除率為82%,達(dá)到GB/T18921-2002景觀用水水質(zhì)要求.當(dāng)硝酸鹽含量急劇下降至0.20 mg/L以下時,反硝化除磷菌不再以硝酸鹽作為電子受體進(jìn)行聚磷活動,厭氧磷釋放的最佳碳磷比為60.添加納米改性的懸浮填料后,好氧池的溶解氧為2.0 mg/L時,出水TP為0.3~0.35 mg/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. 作 者: 劉蕾    尹軍    崔崇威    張立國    林英姿    LIU Lei    YIN Jun    CUI Chong-wei    ZHANG Li-guo    LIN Ying-zi   作者單位: 劉蕾,崔崇威,張立國,LIU Lei,CUI Chong-wei,ZHANG Li-guo(哈爾濱工業(yè)大學(xué)市政環(huán)境工程學(xué)院,黑龍江,哈爾濱,150090)
