摘要
通过对低温二级生化处理出水的深度处理试验,考察分析了有机混凝剂与无机混凝剂在低温环境下去除污染物的效能。结果表明,淀粉和纤维素的处理效果明显高于硫酸铝;当淀粉、纤维素的投药量达到120 mg.L-1左右,处理前浊度为89 NTU、TN质量浓度为21 mg.L-1、TP质量浓度为2 mg.L-1时,处理后的出水浊度小于5 NTU、TN质量浓度小于15 mg.L-1、TP质量浓度小于0.5 mg.L-1,出水水质满足城市污水再生利用景观环境用水水质(GB/T18921-2002)的要求。
Through the depth wastewater treatment experiment of the secondary biological treatment water in low temperature, we analyzed the efficiency of removing pollutant between organic coagulant and inorganic coagulant at low temperature. The results showed that the efficiency of the starch and fibrin were higher than Al2（SO4）3.when the starch and fibrin＇s dosage was 120 rag. L^-1, turbidity, theTN and TP＇ dosage were from 89 NTU, 21 mg. L^-1 and 2 mg.Llwhich was less than 5 NTU, 15 mg. L^-1 and 0.5 mg-L^-1. The effluent quality can meet the requirement of Reuse of Urban Recycling Water-Water Quality Standard for Scenic Environment Use（GB/T 18921 --2002）
