摘　　要：采用三级接触氧化/外置式膜过滤组合工艺对某高校宿舍区生活污水进行处理.在保证出水水质的前提下,通过对各工艺运行参数的优化与控制,水力停留时间较传统接触氧化工艺大为缩短,显著提高了运行效率.运行结果表明:当HRT为3.7 h时,系统对COD的去除率可达到95%,对氨氮的去除率达到93%,对SS的去除率达到100%.系统产水电耗控制在0.6 kW爛h/m3,出水水质满足城市杂用水绿化用水要求,为分散式污水处理提供了一种实用的工艺模式.Three-stage contact oxidation/external membrane filtration process was used for treat-ment of sewage from a college dormitory. On the premise of ensuring the effluent quality, through optimi-zing and controlling the operation parameters, the hydraulic retention time （HRT） was greatly shortened compared with the traditional contact oxidation process, which significantly improved the operation effi- ciency. The operation results showed that when the HRT was 3.7 h, the removal rates of COD, ammonia nitrogen and SS were 95%, 93% and 100% respectively. The electricity consumption of the system was 0.6 kW·h/m^3. The final effluent quality could meet the requirements of using urban miscellaneous wa-ter for greening. This project provides a practical process mode for distributed sewage treatment.
