摘　　要：介绍了镇江市征润州污水处理厂循环式活性污泥法(CAST)的工艺流程、相关设备及构筑物设计参数。污水处理厂位于长江中下游的镇江市北侧,所处理的污水主要是镇江市居民生活污水。CAST生物反应池的构造和运行方式是将好氧、缺氧和厌氧过程很好地结合起来,在一个循环运行周期中同时完成硝化和反硝化过程,有效地进行脱氮除磷。运行结果表明,用CAST工艺处理城市污水,处理效果良好,出水水质达标,操作管理方便,很适合城市、农村和小城镇使用。The treatment processes, facilities of cyclic activated sludge technology （CAST） and its designing parameters of treatment elements in Zhenjiang Zhengrunzhou sewage treatment plant were introduced. The sewage treatment plant is located near the downstream of Yangtze River, the north of Zhenjiang, whose influent is mainly the municipal wastewater. Since the aerobic, anoxic, and anaerobic successive stages were properly incorporated into the CAST operation, nitrification and denitrification might be done simultaneously in one cycle, within the nitrogen and phosphorus removing effectively. The operational results show that CAST is an ideal technology for treating sewage in cities, rural areas and small towns because of its good treatment effect, stable water quality of the effluent and convenient to be operated.
