摘　　要：对运河水用于反渗透进水的预处理方案进行了研究 ,主要为去除水中有机物和降低水的浊度 ,其中包括 :(1 )确定原水中有机物含量及其分子量的分布范围 ;(2 )对混凝剂及其浓度进行选择 ;(3)确定助凝剂和低浊添加剂的作用 ;(4 )原水pH值对混凝效果的影响 ;(5 )NaClO氧化试验 ;(6 )活性炭吸附有机物试验。根据试验结果 。The pretreatment scheme of using water from the Grand Canal as ingoing water of the reverse osmosis system has been studied. The main points are elimination of organics in the water, and reduction of the water turbidity, including: (1) determining the content of organics in raw water and the distribution range of its molecular weight; (2) selecting cogulant and its concentration; (3) defining the effects of cogulating aid and low turbidity additives; (4) considering the infuence of pH value in raw water upon the cogulating effectiveness; (5) conducting oxidation test for NaCIO; (6) performing test of organics abosorbing ability for activated carbon. Based on the results of test, an effective and practical pretreatment process has been put forward.
