高锰酸钾氧化去除饮用水源中草甘膦的试验

Experiment of Glyphosate Removal in Source of Drinking Water by Oxidation Process of Potassium Permanganate

该文以长江水为原水配制一定超标倍数的草甘膦污染水样,研究高锰酸钾投加位置及投加量对去除草甘膦的影响。结果表明:高锰酸钾氧化技术能有效去除草甘膦,且于絮凝初期投加效果较好;可采用10 mg/L聚合氯化铝和2.0 mg/L高锰酸钾,使出水中草甘膦达到《生活饮用水卫生标准》(GB 5749—2006)。

To study the removal effects of glyphosate by changing potassium permanganate dosing print and dosage, Yangtse River water was chosen as the raw water. The glyphosate concentration of water exceeding the standard fixed times were prepared. The study shows that potassium permanganate oxidation technique can effectively remove the glyphosate and better removal effect is appeared at the primary stage of the flocculation. Pepole can use 10 mg/L polyaluminium chloride and 2. 0 mg/L potassium permanganate and make the concentration of glyphosate complies with Drinking Water Health Standards （ GB 5749-2006）.
