| Abstract: | The intensified primary treatment process of municipal wastewater by bioflocculation and adsorption was put forward in this paper.With removal rate of organic substance and SS being studied in detail,this paper discussed the feasibility,influencing factors and running parameters of the process.The results showed that,under the conditions of HRT=1 1 h,DO=1 0 mg/L,COD Cr of sludge=3 4～4 0 kg/d,the removal rate of COD Cr BOD 5 and SS were 68%～78%,65%～72% and 75%～85%,respectively. |
