【摘要】 以富含有机物的地表水为研究对象，通过烧杯搅拌试验与生产性对比试验考察了高锰酸盐复合药剂对高稳定性地表水的助凝效果。结果表明，高锰酸盐复合药剂预氧化助凝能显著提高该地表水的混凝效果，明显提高水质或降低混凝剂药耗，比单纯用聚合铝混凝显著降低沉后余浊。在达到相同沉后余浊情况下，比单纯用聚合铝混凝降低药耗３５ ％ ～３８ ％ 。更多还原

【Abstract】 The effectiveness of enhanced coagulation of stabilized surface water with high organic content by permanganate preoxidation was studied through laboratory jar test and full-scale investigation.It was shown that permanganate preoxidation greatly enhanced the coagulatuon of this water,resulting in obvious reduction of rdsidual turbidity of settled water.To achieve the same residual turdidity,the cogulant dosage of employing preoxidation was reduced by 35%～38% in comparison with the coagulation by using polyaluminum alone.更多还原
