高锰酸盐预氧化与PAM联用处理微污染水的工程研究

某地表水源取自太湖某支流，具有低浊、有机物含量高等微污染的特点。以此地表水为试验原水，提出了高锰酸盐预氧化与聚丙烯酰胺（PAM）联用强化技术。通过小试试验确定了二者具有对浊度和耗氧量的较好的去除效果，据确定生产性试验参数。生产试验结果表明，两者联用后能明显改善水质，出厂水浊度达标率从联用前的15%提高到了82%；联用后沉后水的耗氧量即低于联用前滤后水的耗氧量水平，沉后水的耗氧量的去除率达到43.00%。

Engineering Research on Micro-polluted Water by Combined Use of Permanganate and Polyacrylamide

Aiming on the micro-polluted surface water, which had low turbidity and high organism, in Tai-Lake, a combined use of permanganate and polycrylamide was put forward. Small scale test showed that permanganate and polycrylamide both had better removal of turbidity and CODMn, further the parameters of large scale test were determined. Large scale test showed that the combined use of permanganate and polycrylamide had better improvement of water quality, the percent of pass of effluent was lifted from 15 to 82; the CODMn of the water from sedimentation after combined use was lower than the water from filtration before combined use, the removal rate of water from sedimentation was up to 43 percent.
