绍兴市柯桥主城区水质提升工程的实践

Water Quality Promotion Engineering in Keqiao

柯桥主城区属于典型的平原河网地区,水体流动性差,水环境问题突出.结合平原河网特点,对柯桥主城区河道水环境采取"分隔水系、引水换水、先排后引、截污清淤"的网格式封闭型换水活水,实践表明,通过水系分隔引水换水等方案的实施能够有效利用水动力,在水质改善等方面的综合效果明显,对推进平原河网地区"五水共治"具有借鉴意义.

The main urban of Keqiao is typical plain river network area,with poor water fluidity and serious water problems.Combined with the characteristics of plain river network,the practice of enclosed water exchanging is conducted in order to improve water environment in the main district of Keqiao by separating drainage system,launching water diversion,and sewage dredging. The result shows that the practice of drainage system separating and water diversion effectively improve the water quality in the plain river network region,which provides significant reference for comprehensive treatment of water resources.
