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。
Removal of AOC and BDOC in source water using pre-chlorination ＋ convennonal 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.
