Shaoqi Shi Lin Yuan et als. (Qinghua university,Beijing) Ruchang Huang (The Hong Kong Univ.of Science and Technology)
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.
