摘　　要：针对污水处理厂进水水量波动大、NH_(3)-N浓度偏高、COD浓度偏低的特点,在A^(2)/O工艺生化池中投加固定床平板填料强化处理效果。试验结果表明:在A^(2)/O工艺生化池中投加固定床平板填料的污水处理厂对COD的去除率可以稳定在90%左右,对NH_(3)-N的去除率则可以维持在95%左右,出水水质达到GB 18918—2002《城镇污水处理厂污染物排放标准》中一级A标准。In view of the characteristics of the influent water of a sewage treatment plant such as:large fluctuation of water quantity,high NH_(3)-N concentration,low COD concentration and so on,a fixed bed plate filler was added to the biochemical pond in A^(2)/O process to enhance the treatment effect.The experimental results showed that,the wastewater treatment plant with fixed bed plate filler added to the biochemical pond in A^(2)/O process can maintain a stable COD and NH_(3)-N removal rates of about 90%and 95%respectively.The effluent water quality met the requirement of level A grade 1 in GB 3838—2002 Environmental quality standards for surface water.
