摘    要:在对引江济太调水工程前期研究的基础上,对2007年无锡供水危机事件和2008年冬春季引水中引江济太工程的作用进行了系统分析。在2007年无锡供水危机爆发1周内,随着引江济太调水工程的进行,贡湖水厂水源地溶解氧和氨氮等水质指标从劣Ⅴ类转变为Ⅲ类,小湾里水厂和锡东水厂水质也有好转;在2007年下半年和2008年上半年调水条件下,2008年5月与去年同期相比,贡湖高锰酸盐指数、总磷和总氮质量浓度分别从7.04 mg/L、0.106 mg/L、4.10 mg/L下降到3.35 mg/L、0.087 mg/L、2.87 mg/L,氨氮水质指标保持在Ⅲ类,表明引江济太调水工程对改善太湖局部湖区水质、保障太湖供水安全具有重要意义。最后提出了进一步推动引江济太调水工程长效化运行的对策措施建议。

关 键 词:引江济太调水工程  太湖  水质改善

Abstract:On the basis of pilot studies on the water diversion from the Yangtze River to Taihu Lake (WDYT), the influence of WDYT both on the water supply crisis in Wuxi City in 2007 and from January to June in 2008 were analyzed systematically. During the one-week water supply crisis in Wuxi City, water quality indexes such as dissolved oxygen and ammonia in water sources of the Gonghu water supply plant improved from category Ⅴ to category Ⅲ when the WDYT went into operation. According to the national water quality standard, the water quality of the Gonghu water supply plant and the Xidong water supply plant also gradually improved. WDYT was in operation in the second half of 2007 and the first half of 2008. The concentration of the permanganate index, the total phosphorous, and the total nitrogen in Gonghu decreased from 7.04 mg/L, 0.106 mg/L, and 4.10 mg/L in May 2007 to 3.35 mg/L, 0.087 mg/L, and 2.87 mg/L, respectively, in the same period of 2008. The concentration of ammonia nitrogen held the water in category m The results showed that WDYT was very important to the improvement of the water quality in part of the area and to guaranteeing water supply in Taihu Lake. Countermeasures to advancing long-term operation of WDYT were finally promoted in the paper.
Keywords:Water Diversion Project from Yangtze River to Taihu Lake(WDYT)  Taihu Lake  water quality improvement
