摘要: |
在对太湖流域水质状况进行分析的基础上,指出因水污染造成的水质型缺水问题在太湖流域十分严重,正常年份流域优质水资源缺水量在(20-35)×108 m3之间.如今后水质型缺水问题长期得不到解决,有可能影响流域经济社会可持续发展.针对流域水质型缺水的特点,提出在加强流域水污染治理同时,太湖流域宜选择以长江、太湖和山区水库为主要水源地的长期供水格局,当前要抓紧建设"引江清水通道",调引长江优质水资源入太湖.同时鉴于太湖流域水环境承载能力有限的情况,建议流域沿江、沿海、沿杭州湾城镇的生活污水在二级处理的前提下,应实施流域尾水截流外排管道工程. |

Abstract: |
At present, the water pollution has become a severe problem in the Taihu Basin. The water scarcity caused by pollution has annually reached to 2-3.5 billions m3 in the basin. The water pollution will be a big problem in the next few decades, which may affect the sustainable socio-economic development in the Taihu Basin. On the base of water pollution control in the Taihu Basin, it is suggested that the Yangzhe River, Taihu Lake and the reservoirs in the mountainous area in the upper reaches should be chosen as the main drinking water sources in the long term and more clean water from River Yangtze into Taihu Lake be diverted in order to meet the need of supplying enough water with better quality. It is also suggested to discharge the wastewater from the basin to the East Sea and Hangzhou bay after the secondary treatment. |
