EXPERIMENT ON THE TREATMENT OF WASTEWATER WITH HIGH AMMONIA CONCENTRATION IN SINGLE-STAGE ANOXIC/AEROBIC HYBRID SUBMERGED MEMBRANE BIOREACTOR

2007 
采用单级A/O程序复合膜生物反应器(HSMBR)处理高氨氮废水,研究在低DO浓度下系统对有机物、氨氮和总氮的去除效率.研究结果表明:在低DO浓度下,CODCr、氨氮的平均去除率分别为94.4%和92.8%.由于进水CODCr/TN值仅为2.01,则使得总氮平均去除率仅为69.4%,但是当系统亚硝化累积率从60.5%~67.1%提高到83.5%~86.4%时,系统总氮去除率提高了17.7%.另外,维持低DO浓度可以实现亚硝酸型同时硝化反硝化反应.
