摘　　要：采用活性污泥 接触氧化法处理印染废水 ,取得了满意效果。在低温季节半年多的工程运行中 ,进水平均CODCr浓度为 5 67± 40 0mg L ,平均色度为 416± 3 7 1倍时 ,出水平均CODCr浓度 79 7± 6 0mg L ,去除率为 84 1± 1 7% ;平均色度 5 2 8± 4 0倍 ,去除率为 85 2± 1 3 % (置信度为 95 % )。处理成本低 ,仅为 0 79元 m3,污泥产量小 。A satisfactory result has been obtained due to the treatment of dyeing wastewater by the activated suldge-contact oxidation process.During more than 6 months operations at low temperature,the average COD Cr,average colority and removal rate of the effluent were 79.7±6.0 mg/L,52.8±4.0 times and 84.1±1.7% respectively when the average COD Cr and the average colority of the influent were 567± 40.0 mg/L and 416±37.1 times.This process features a low cost (only 0.79 yuan/m 3),less amount of sludge and conveninet management.
