摘要
试验研究了常规处理工艺(混凝-沉淀-砂滤)对饮用水中有机物的去除,结果表明:常规处理工艺对CODMn去除效果较差,平均去除率为16.7%,且受到进水CODMn含量和水温的影响,水样CODMn含量高和水温高时,CODMn的去除率高;对NPOC的平均去除率为11.6%,效果较差;常规工艺对AOC几乎没有去除作用,多数情况下出厂水AOC浓度在氯的氧化作用下升高,平均增加55.3%;出厂水AOC平均为160.63μg/L,属于生物不稳定饮用水。
Removal of natural organic matter in drinking water by conventional treatment process （ coagulationsedimentation-sand filtration） was investigated in north China. Average removal efficiency of CODMn by conventional treatment process was 16. 7%. The removal efficiency was influenced by the concentration of CODMn of raw water and temperature, which was better when the both were high. Removal efficiency of nonpurgeable organic carbon （NPOC） was 16. 7%. Assimilable organic carbon （AOC） concentration increased 55.3% after treatment because of chlorination. Average AOC concentration of treated water was 160. 63μg/L. The drinking water cannot meet a biostability criteria of 10 μg/L.
