中文摘要	根据昆明市第一污水处理厂深度处理微絮凝-D型滤池工艺的运行数据,评价了工艺出水水质及总磷(TP)去除效果,同时分析了混凝剂投加量及药剂费用。结果表明,微絮凝-D型滤池工艺出水TP平均浓度为0.15 mg/L,最优水平值为0.05 mg/L,95%保证值为0.37 mg/L,TP平均去除率为63.6%。出水悬浮固体(SS)浓度95%保证值为10 mg/L。混凝剂聚合氯化铝(PAC)的投加量在1.5~4 mg Al2O3/L范围波动,去除单位TP的PAC投加量平均值为16.7 mg Al2O3/mg-P,投加比为2~8 mol-Al/mol-P。当投加比超过5时,出水TP浓度可达到0.3 mg/L以下。吨水PAC成本平均值为0.017元/t。; The effluent quality,removal efficiency of total phosphorus(TP),dosages and cost of coagulant of the micro-flocculation-D type filter process in Kunming No. 1 WWTPs were studied. The average TP concentration of the effluent of the process was around 0. 15 mg /L with an average removal efficiency of TP of 63. 6%.The lowest level of effluent TP concentration of the process was 0. 05 mg /L and the 95%-reliably achievable level of it was 0. 37 mg /L. The 95%-reliably achievable concentration of suspended solids(SS) of the process was 10 mg /L. The dosage of poly-aluminum chloride( PAC) changed during 1. 5 ~ 4 mg Al2O3/L,and the average PAC dosage to remove TP was 16. 7 mg A2O3/mg-P. The initial Al /P molar ratio was about 2 ~ 8,and the effluent TP concentration could be less than or equal to 0. 3 mg /L when initial Al /P molar ratio was higher than 5.The average cost of PAC was 0. 017 RMB /t.
