摘　　要：生产性试验证实过氧化氢预氧化是替代预氯化的有效、方便、经济的办法。过氧化氢预氧化本身产生的有效氯很少 ,可以显著去除水中低分子量的溶解性有机物 ,从而减少消毒产生的有机氯。过氧化氢预氧化还能明显抑制藻类生长。试验中采用人工锰砂催化剂 ,但发现地面水水厂滤池中的石英砂经过长时间运行后 ,也会自然熟化成为催化性能良好的人工锰砂 ,所以过氧化氢预氧化可以采用普通石英砂滤池。生产性试验期间出厂水水质良好 。It is approved by long time full scale experiments that hydrogen peroxide is effective, convenient and economical to replace the chlorine for drinking water pre oxidation. The content of dissolved low molecule organic substances decreased evidently without residuals of available chlorine, so the problem of chloro hydrocarbon buildup in chlorine desinfection was eliminated. Also the algae growth was inhibited by hydrogen peroxide. In the experiment artificial manganese sand was adopted as catalyst of oxidation; but it is found that quartz sand media common used in every waterworks could be adapted in ageing of long time operation into maturation as effective catalyst agent. Therefore the common sand filter will be easy to adopt the peroxide per oxidation. The output water quality of the experiment is quite good, and some main indicators are better than the requirement of the national drinking water standard.
