天津于桥水库主要环境问题及其防治对策

The Environmental Problems and Controlling Countermeasures of Tianjin Yuqiao Reservoir

于桥水库是引滦入津工程重要调蓄水库,也是天津市人民生活饮用水和工农业生产用水的水源地。近10多年来,于桥水库流域和湖周的社会经济发展迅速,入库污染负荷急剧增加,水库水质也随之恶化。目前水库已处于重富营养状态,水质达Ⅴ类。运用控源和生态修复相结合的湖泊富营养化控制理论开展总体设计,提出了于桥水库污染综合治理的工程方案和对策。

The Yuqiao Reservoir, an important adjusting reservoir in the project of diverting water from the Luan River to Tianjin City, functions as the water resource for the water supply of drinking, industry and agriculture of the municipality Tianjin City. The society and economy of the basin developed fast for the last decade and the pollution loading increased sharply. This has led to the deterioration of the water quality of the reservoir. Currently the reservoir has been eutrophicated and the water quality reached Level Ⅴ. The overall design was conducted based on the eutrophication control theory combining the source control and ecological rehabilitation, and the engineering schemes and countermeasures of integrated pollution treatment for Yuqiao Reservoir proposed.
