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)。
In this paper, the city of several waterworks in different seasons of raw water, factory water and the tip of the water humic acid, halogenated hydrocarbons and volatile organic compounds were determined. The results showed that the seasons were the important factors affecting the humic acid content. Humic acid was the main precursor of carcinogenic halogenated organic compounds, and its content was positive with its chlorinated products - halogenated hydrocarbons and non-volatile organic compounds (P <0.05). There was significant difference in the content of halohydrocarbons between the experimental area and the control area in the wet season (P <0.05).
