Now proposing a sewage treatment plant in Fuxin city, deal with the scale of 60000m3/d.To achieve the required effluent standards,compared to a variety of techniques,Based on the present design，using biological contact oxidation process combined with the depth of processes to deal with municipal sewage.The method is a modern sewage treatment plant processes commonly be used. The method is simple, easy operation,removaling nitrogen and phosphorus well,eliminating sludge return process,producing less sludge,less prone to sludge bulking,and power consumption is not high,and the utilization of the method of the pond is high, saving construction investment and operating costs.Key words: municipal wastewater; biological contact oxidation; depth of treatment; sludge treatment目录前言····························································································11 设计概论···················································································21.1 设计任务·················································································21.2 设计原则·················································································21.3 设计依据·················································································21.4 阜新市概况及自然条件·················································
