摘要
以膨润土为原料制备活性白土,并利用反应后产生的废液制备聚氯化铝(PAC)。研究了PAC用量、微污染水pH、不同温度制备的活性白土以及活性白土与PAC联用对微污染水处理效果的影响,以确定活性白土与PAC协同作用对微污染水处理的最佳实验条件。实验结果表明,活性白土与PAC联用,且活性白土用量为0.20 g、PAC用量为0.20 mL时可达到最佳的水处理效果,微污染水CODCr去除率高达79.40%、剩余浊度为0.6 NTU。
Activated clay was prepared by bentonite and polyaluminum chloride was prepared by the waste fluid in the prepa-ration of activated clay.The influences of dosage of PAC,pH of the micro- polluted- water,activated clay prepared at different temperatures,and the application of PAC and activated clay on the micro- polluted- water treatment effect were studied,and the optimal experiment conditions were confirmed.Results showed that the treatment effect for micro- polluted- water was better when the activated clay was used with PAC,especially when dosage of the activated clay was 0.20 g and the amount of PAC was 0.20 mL,CODCrremoval rate ofthe micro- polluted- watercould reach upto 79.40%and the residual turbiditywas 0.6 NTU.
