【摘要】 基于CWSBR反应器的构造和工艺运行过程,根据污水水质数据和工程实际确定了污水处理厂的CWSBR处理工艺流程。工程实施后的实际运行结果表明,污水出水水质满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。工程应用证明,CWSBR工艺易通过调整进水时间及工作周期和控制反应池的溶解氧水平来创造厌氧、缺氧和好氧交替的环境,具备高效脱氮除磷功能,具有良好的应用价值。更多还原

【Abstract】 Based on the structure and running state of the reactor, CWSBR process is adopted in WWTP according to the sewage quality and the actual situation of the plant. Actual running results show that the effluent quality meets the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB18918-2002). Engineering application has shown that CWSBR process is easy to create an environment of anaerobic, anoxic and aerobic conditions by adjusting the influent time, working period and controlling the dissolved oxygen level in the reaction tank. This process has the function of high efficiency nitrogen and phosphorus removal, and has good application value.更多还原
