摘要

采用微库仑法，分析常州市武南区域地表水和污水处理厂出水中可吸附有机卤素（AOX）的浓度，揭示了该区域AOX的污染特征.结果表明，区域内地表水中AOX的年均浓度为41.9μg/L，与其他研究结果相当或偏低，夏季浓度高于冬季.从空间分布上看，永安河中段、滆湖北部和京杭运河以北区域污染相对严重，其中断头浜截流是造成AOX污染突出的一个重要原因.市政污水处理厂和纺织工业污水处理厂出水的年污染负荷较高，是两类重要的排放源，对地表水中AOX污染有较大的贡献.

Abstract

Concentrations of adsorbable organic halogens (AOX) in surface water and effluents of wastewater treatment plants (WWTPs) in Wunan area of Changzhou were analyzed by microcoulometry, and the AOX contamination characteristics in this area were revealed. Results showed the mean concentration of AOX in surface water was 41.9μg/L, similar to or lower than those in other researches. More severe contamination of AOX was observed in summer, and in the middle section of Yongan River, the north part of Gehu Lake and the northern part of Jinghang Canal. The blocking of river was regarded as an important cause for the severe AOX contamination. Annual pollution loads of AOX from municipal and textile WWTPs were higher, reflecting the large emission contributions by these two sources to the surface water.
