隨著城市化進程的加快和經濟建設的飛速發(fā)展，城市污水排放量也迅速增加，大量未經處理的污水任意排放，將對水體造成嚴重污染。 sewage treatment plant effluent water after treatment to achieve effluent discharge standards integrated wastewater discharge standard ( GB89781996 ) standard. The sludge treatment process for: it into the mud storage tank primary settling sludge tank sludge and two sedimentation tank produced, after storing mud, adding the sludge after treatment, into the sludge thickening and dewatering workshop, finally outward processing.Keywords: A2O process。污泥處理流程為：初沉池產生的污泥和二沉池產生的剩余污泥則送入貯泥池，經過貯泥、加藥處理后的污泥，進入污泥濃縮脫水車間，最后外運處理。該污水處理廠工程規(guī)模為 19 萬噸/日，進水水質見下表表 1 進水水質（單位：mg/L）指標 CODCr BOD5 SS 氨氮磷酸鹽（以 P 計）數值 180 140 180 35 本次設計所選擇的 A2O 工藝，具有良好的脫氮除磷功能。JIU JIANG UNIVERSITY 《水污染控制工程》課程設 計 題 目 12 萬噸/日城市污水處理廠的初步設計 英文題目 The Preliminary Design of 120220 ton
