摘要
针对山岳型景区污水低C/N、低温、高油、高SS等特点,采用“气浮-A^(2)-化学除磷-S自养反硝化”工艺进行了处理。实际运行结果表明:设计工艺启动周期短,运行维护简单,具有较高的处理效率,COD、NH_(3)-N、TN、TP去除效率分别为92.5%、99.6%、92.0%、97.4%。出水稳定达到了《城镇污水厂污染物排放标准(GB18918-2002)》一级A标准,可为同类污水处理工程提供参考。
In view of the characteristics of low C/N,low temperature,high oil and high SS,the sewage in mountain-type scenic spots is treated by the process of"air flotation-A^(2)O-chemical phosphorus removal-S autotrophic denitrification".The actual operation results show that the designed process has advantages of short start-up cycle,simple operation and maintenance and high treatment efficiency.The removal efficiencies of COD,NH_(3)-N,TN and TP are 92.5%,99.6%,92.0%and 97.4%respectively.The effluent is stable and meets the class A standard in the Discharge Standard of Pollutants for Urban Sewage Plants(GB18918-2002),which can provide reference for similar sewage treatment projects.
