摘　　要：曝气混凝沉淀不仅其水质优于机械混凝沉淀的水质,而且其沉淀污泥的性能也好于机械混凝沉淀的性能.曝气混凝沉淀污泥的初期沉降性能稍差,但后期具有与机械混凝污泥类似的沉降过程;曝气混凝沉淀污泥的含水率较机械混凝沉淀污泥的含水率低一个百分点,其最大值为94%,最小值为92%;曝气混凝沉淀污泥的比阻低于机械混凝沉淀污染的比阻,表明具有良好的脱水性能;曝气混凝沉淀污泥的浓度(MLSS)高于机械混凝沉淀污泥的浓度,而有机分(VSS)含量却低于机械混凝沉淀污泥,这从另一方面证实了曝气混凝效果的提高.The water quality treated by aeration coagulation sedimentation is superior to the one by mechanism coagulation,and the performance of the sludge by aeration coagulation sedimentation is also better than that of the mechanism coagulation.The initial stage of sedimentation performance by aeration coagulation is not quite satisfactory,but the later stage has the kind of sedimentation process similar to that of the mechanism coagulation.The moisture content of the sludge by aeration coagulation sedimentation w...
