摘要建立了臭氧-牡蛎壳固定床生物反应器（OFBR）和膜生物反应器（MBR），对城市尾水进行了深度处理，并运行了半年左右。中试结果表明，OFBR-MBR对碳、铵、磷具有较高的去除率，对化学需氧量、铵、总氮、总磷（TP）的平均去除率分别为75%、99%、20%和40%。城市尾水中的难降解有机物在OFBR中转化为可生物降解的有机物，MBR有效拦截了剩余的微分子有机物和微生物。在OFBR-MBR中，铵大部分转化为硝酸盐，其中约10%通过常见的好氧氨氧化细菌、亚硝酸盐氧化细菌和反硝化细菌的硝化和反硝化作用释放为氮气。污泥中TP含量丰富，当污泥负荷增加时，可通过剩余污泥排放去除TP。
Abstract An ozone-oyster shell fixed-bed bioreactor (OFBR) and a membrane bioreactor (MBR) were constructed and operated for about half a year for the deep treatment of municipal tail water. Pilot-scale test results showed that the combined OFBR-MBR had high removal efficiencies for carbon, ammonium, and phosphorus, and mean removal efficiencies for chemical oxygen demand, ammonium, total nitrogen, and total phosphorus (TP) were 75%, 99%, 20%, and 40%, respectively. Refractory organics in the municipal tail water were transformed to biodegradable organics in the OFBR, and the MBR effectively intercepted the surplus micro-molecular organics and microbes. Ammonium was mostly converted to nitrate, ∼10% of which was released as nitrogen gas through nitrification and denitrification by commonly known aerobic ammonia-oxidizing bacteria, nitrite-oxidizing bacteria, and denitrifying bacteria in the OFBR-MBR. The sludge was enriched in TP, which could be removed via surplus sludge discharge when sludge loading inc...
