摘　　要：提出一级污泥絮凝吸附——沉淀工艺，利用回流一级污泥的絮凝吸附作用强化一级沉淀处理。试验证明，处理未经沉淀的生活污水，当ＨＲＴ为１０５ｍｉｎ，絮凝池污泥浓度１～２ｇ／Ｌ、污泥充氧时间１ｈ左右时，ＣＯＤ和ＳＳ的去除率分别为６０～７０％和７０％左右。A process of bioflocculation-adsorption for intensifying primary sedimentation by recycling primary sludge was developed in this study.Experimental results demonstrated that when the process was used for the treatment of unsettled domestic wastewater at HRT 105 min,sludge concentration 1～2g/L in flocculation tank and aeration time 1h,removal efficiencies of COD and SS were 60～70% and 70%,respectively.
