高锰酸钾氧化白石水库低温微污染水的试验研究

Research on the Potassium Permanganate Oxidation of Baishi Reservoir's Slightly-polluted Water at Low Temperature

为了给低温微污染水源水的处理提供可靠可行的工艺参数,通过烧杯静态试验,分别研究了水温、pH值、氧化时间等因素对高锰酸钾预氧化反应的影响,以及高锰酸钾预氧化在常规水处理工艺基础上的净水效能.试验结果表明对于北方冬季低温微污染水,高锰酸钾预氧化能有效地去除部分有机物,并起到良好的助凝除浊除微污染作用,使处理后水质达到标准.并指出高锰酸钾投加的最佳剂量应根据原水水质确定其最佳投药量范围,投加位置也可根据原水水质适当选择.

Effect of water temperature,pH value,oxidation time on potassium permanganate oxidation and oxidation efficacy on the basis of conventional water treatment process were studied by beaker static test to provide invisible process parameter,respectively.The results showed that potassium permanganate oxidation on winter slightly-polluted water at low temperature in Chinese north area could remove some part of organic effectively and aid coagulation to remove turbidity and slight-pollution significantly to make the treated water quality reach standard.The optimal dosage of potassium permanganate should be defined according to the source water quality,as well as the dosing point.
