摘　　要：根据对宜兴市污染源分析,结合当地10座污水处理厂的实际调查,在现阶段排放标准下,利用等标污染负荷法评价出污水厂出水的污染特征;同时,对各污水厂进行污染程度排序,筛选出主要污染源区域及其主要污染物。对比分析表明,污水厂出水一级A标准个别指标超过地表水V类水质标准多倍,其出水入河仍对水环境污染负荷有一定影响;就宜兴污水处理厂而言,等标污染负荷分析表明,宜兴清源污水处理厂为主要污染源,出水污染物中TP和COD为其主要污染物。According to the analysis pollution sources of Yixing and integrating with actual survey of 10 local wastewater treatment plants(WWTPs),the characteristics of water pollution were evaluated by the equal standard pollution load approach under the current discharge standard.At the same time,the main pollution source areas and pollutants were selected by sorting all the WWTPs based on their pollution degree.Comparative analysis showed that some indexes of the WWTP effluent standard 1A comparatively exceeded the V class water quality standards of surface water,the effluent into the river still had certain influence on the water environment pollution load.In terms of WWTPs of Yixing,the equal standard pollution load analysis indicated that Qingyuan WWTP was the main pollution source and TP and COD in its effluent were the main pollutants.
