| Abstract: | This article aims at examining the treatment effect of municipal sewage plants, and thus providing referential valve to the operations of sewage plants by simulating a small-scaled tester using CASS technique which is according to treatment system of municipal sewage plant. Design of the tester using CASS technique and its key parameters are sludge load 0.065 kg·BOD5·kg-1·MLSS·d-1), ratio of draining 1/3, HRT 18.5 h. Its reaction period contains influent 0.5 h, influent-aeration 1 h, aeration 2 h, sedimentation 1 h, and effluent 1.5 h. Effluent quality meets the requirements GB18918-2002 Standard for Discharge of Pollutants from Sewage Treatment Works in Towns and Cities B. |
