摘要
本文对某市几个自来水厂不同季节原水、出厂水和未梢水中腐殖酸、卤代烃及挥发性有机物的含量进行了测定。结果表明,季节是影响腐殖酸含量的重要因素;腐殖酸是具致癌作用的卤代有机物的主要前驱物质,且其含量与它的氯化产物——卤代烃、非挥发性有机物呈正相关关系;丰水期实验区与对照区末梢水中卤代烃含量的差异有显著性意义(P<0.05)。
The measurement of humic acid、 trihalom- ethanes and nonvolatile organic compounds in raw water、 chlorinating water and tip water of several waterworks were carry out in two dis- tinct seasons. The results showed that the sea- son is a dominant factor influencing humic ac- id content; humic acid is main precursor of ca- rcinogenic trihalomethanes; the humic acid co- ntent is direct proportion with its chlorinating products——trihalomethanes,nonvolatile organic compounds. In addition the content of trihalo- methanes, in the tip water was statistically hi- gher in the experimental zone than in control zone.
