粉末活性炭工艺强化处理黄浦江下游原水的试验研究

Enhanced Treatment of Raw Water from Lower Reaches of Huangpu River by Powdered Activated Carbon Process

采用投加粉末活性炭(PAC)进行强化黄浦江下游原水常规工艺处理效果的试验,结果表明:调节pH值为6.0～6.5,在投加混凝剂(硫酸铝)30 mg/L,2 min后投加20 mg/L的PAC,经过絮凝、沉淀、砂滤后,对CODMn的去除率大于50%,PAC的净去除率大于10%,且该组合工艺对锰去除效果明显。

Powder activated carbon （PAC） was added to strengthen the treatment efficiency of raw water from Huangpu River by the conventional treatment processes. The experimental results indicated that under the reaction condition of pH 6.0-6.5, dosage of Al2（SO4）3 as 30 mg/L, dosage of PAC as 20 mg/L （which was added at two minute later after adding of A12（S04）3）, the removal efficiency of CODMn by the combined processes of PAC and conventional treatment was more than 50%, the net removal efficiency of PAC was more than 10%. And Mn could also be well removed by the combined nrocesses.
