天府新区某湖泊水环境综合治理技术

Comprehensive Environmental Management of a Lake in Tianfu New District

通过对成都市天府新区某湖泊水文、水质和污染现状的分析,提出控制性河湖分离、清水型水生态系统和环湖生态驳岸带综合治理技术,并采用MIKE 21水动力和水质模块模拟一定进水条件下的水质稳定变化趋势。经模拟分析和监测数据验证,在一定的进水水质条件下,该综合治理技术可以实现湖区水质稳定达到地表Ⅳ类水质标准。

Based on the analysis of hydrology, water quality and pollution status of a lake in Tianfu New District in Chengdu, the comprehensive treatment technology of controllable river-lake separation,clean water ecosystem and ecological revetment zone around the lake is put forward. The hydrodynamics and water quality modules of MIKE 21 are adopted to simulate the stable change trend of water quality under certain water conditions. After simulation analysis and monitoring data verification, the water quality of lake area can meet level Ⅳ criteria of the Environmental Quality Standards for Surface Water(GB 3838-2002) stably under certain influent water quality conditions by the comprehensive treatment technology.
