连续过滤处理微污原水试验研究

Study on continuous filtration of treating micro-polluted water

基于对连续过滤最佳运行参数研究的基础上,研究原水水质对连续过滤出水的影响.研究发现原水浊度的影响连续过滤的主要因素,pH对以聚合铝为絮凝剂的连续过滤出水影响不大,温度对连续式砂滤器出水影响很大,采用高锰酸钾-粉末活性炭-连续过滤联合工艺处理受污染原水具有较好的除污染效果,处理结果均优于单纯的活性炭吸附或单纯的高锰酸钾氧化的情况.

Based on optimal working parameter about continuous filtration, effect of influent water quality on continuous filtration is studied in this paper. Researches reveal that influent turbidity is the main factor which effects continuous filtration, pH has little effect on continuous filtration when flocculation PAC is used, temperature has big effect on continuous filtration. Combined possess of potassium permanganate-powered active carbon-continuous filtration is used to treat mirco-polluted water. The combined process excel process of potassium permanganate-continuous filtration, process of powered active carbon-continuous filtration and has better affect on removing COD_(Mn) and NH_4-N.
