摘要/Abstract

摘要： 本文主要为解决低温下单独混凝对纺织废水处理效果不佳的问题。实验分析了三种混凝剂的最佳投药量，比较了活性炭投加方式对混凝效果的影响，并研究了低温条件下混凝-活性炭联合工艺对纺织废水的处理效果。实验结果表明：常温下(20-30℃)，BAC效果最好，最佳投药量为100mg/L，对原水中化学需氧量CODCr、色度和总磷TP的去除率分别为51.44%、70.00%和93.48%，而在低温下(10-15℃)只有31.60%、50.00%和75.36%。采用混凝-活性炭联合工艺后，20mg/L活性炭在PAC之前投加时，对CODCr的去除率达到了73.80%。

Abstract: The study was in order to solve the problem that the effect of treatment by coagulation single was not satisfied at low temperature. In the study, the best dosage of the coagulants and effect of the coagulation due to the way of adding, and the effect of coagulation-activated carbon at low temperature were analyzed. The results showed that at normal temperature (20-30℃), the effect of BAC was best , the removal of CODCr, chromaticity and TP by BAC were 51.44%, 75.00% and 93.48% when its concentration was 100mg/L. With comparison, there were 31.60%, 50.00% and 75.36% at low temperature (10-15℃). After the coagulation-activated carbon was used, there would be higher removal when the activated carbon was added before PAC, and removal of CODCr could be 73.80% when the concentration of activated carbon was 20mg/L.
