摘要
研究用碱式PAC和PAM处理发泡剂废水,考察了酸度、碱式PAC的用量、搅拌时间、PAM的用量、温度对CODCr去除的影响。实验结果表明:调解废水pH值在5～7之间,能够沉降大部分的悬浮物,出水澄清,CODCr明显降低;废水中加入的碱式PAC最佳量在1700mg·L-1,出水水质最好;搅拌时间20min以上,出水水质基本稳定。
Alkaline PAC and PAM were used to treat ADC Vesicant Wastewater, the acidity, alkaline PAC usage, stirring time, PAM usage and temperature＇s were inspected to the influence of CODcr removal. The results showed ： when wastewater pH was 5 - 7, most of tthe suspensions were settled , the effluent was clear and Significantly CODcr was lower; when the volume of alkaline PAC into wastewater was about 1 700 mg·L^-1, the effluent was best; when stirring time was set for 20 minutes, the effluent quality was stable.
