摘　　要：一种新型的生物脱氮除磷工艺——双循环两相生物脱氮除磷工艺,它是在序批式活性污泥法基础上增设独立的生物膜反应器,实现微生物的分相培养,对提高脱氮除磷效率、增强系统运行的稳定性和可靠性提供了很大的潜力。通过对城市污水的试验,结果表明,在适宜的负荷和运行条件下TP去除率可达90%,出水TP浓度可控制在1·0mg/L以下。The performance of a new biological nutrient removal process——BICT (bi-cyclic two-phase biological process) is studied based on application-scale experiments with municipal sewage.The new system consists of an independent attached-growth reactor and a set of suspended-growth sequencing batch reactors.The configuration and operation modes of the process provide a good potential for optimizing the operation conditions according to the specific requirements,especially for increasing the stability and reliability of the process.According to the experimental results with municipal sewage,the process has strong and stable capability for phosphorus removal.Under suitable conditions,the removal rate of TP(total phosphorus)is over 90%,and the effluent concentration of TP can be controlled below and 1.0 mg/L.
