摘要
利用污泥的絮凝吸附作用，采用回流污泥絮凝吸附－沉淀－曝气再生工艺，改善城市生活污水的一级处理效率。ＣＯＤ去除率达到６８９％，ＳＣＯＤ去除率为４１％，ＢＯＤ５去除率６６５％，ＳＳ去除率高达８６８％，有机氮和总磷的去除率分别为５１％和２４２％，对氨氮基本没有去除效果，去除率只有４２％
Abstract Using the flocculation and adsorption feature of sedimentation sludge
a scheme based on the flocculating adsorption sedimentation aerobic regeneration process was
adopted to improve the mechanical treatment of municipal wastewater. Removal ratios of 68.9%,
41%, 66 5%, 86 8%, 51% and 24 2% have been obtained for COD, SCOD, BOD 5, SS, organic
nitrogen and total phosphorus respectively. The removal of ammonia nitrogen is low, only 4.2%.
