| 摘 要： | 试验研究了预氯化+常规处理工艺(混凝-沉淀-砂滤)对某水源水中AOC和BDOC的去除,结果表明:水源水中AOC和BDOC占总有机碳(以NPOC计)的比值都在9.5%左右,AOC和BDOC含量基本相同,平均质量浓度分别为316.2μg/L和329μg/L。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71%;出厂水AOC平均质量浓度为206.4μg/L,属于生物不稳定饮用水。BDOC的平均去除率为63.8%,偏高于一般研究结果。

| Abstract: | Removal of AOC and BDOC in source water using pre-chlorination + conventional treatment process(coagulation-sedimentation-sand filtration) was investigated through the test.The results showed that: the content of AOC and BDOC in source water were similar,which were about 9.5% of the total organic carbon(calculated by NPOC),and the average mass concentrations of them were 316.2 μg/L and 329 μg/L respectively.The conventional treatment process has little effect on AOC removal,in most conditions,with chlorine oxidation,the concentration of the effluent AOC increased 71% on average,reached 206.4 μg/L,which was biologically unstable drinking water.The average removal rate of BDOC was 63.8%,a little higher than ordinary results. |
