北京大学燕园校区水质分析与校园水环境保护

Water Quality Analysis and Campus Water Environment Protection in Yanyuan Campus of Peking University

为确保燕园校区的饮用水、景观水、排放污水的水质达标,根据相关规范和标准对检测数据进行分析,发现在没有人为因素影响下,燕园校区的各类水质均达到或高于国家标准。在燕园污水排放方面,部分排水口检测值偏高,在现有的条件下尽量减少指数偏高排水口附近的用水设计规划,科学减少污水排放,从源头控制污水排量。学校在燕园校区的景观水环境保护投入了大量人力物力,实施了未名湖治理工程,将未名湖区域水体改造为自循环,并进行了清淤疏通;将未名湖北侧的后湖区域进行清淤改造,重新打造了后湖区域的生态景观;实施西校门外蔚秀园湖区的清淤改造,实现了整体湖区的灌溉。为营造舒适、宁静的校园环境提供了支撑,为学校进入世界一流大学、培养世界一流人才提供了保障。

The Environmental Protection Office of Peking University has determined the water quality indexes of drinking water,landscape water and discharged sewage in Yanyuan campus for many years,analyzed the test data according to the relevant specifications and standards,and found that under the influence of no human factors,the water quality of all kinds of water in Yanyuan campus of Peking University has reached or exceeded the national standards. In terms of wastewater discharge in Yanyuan,some outlets have high values. Under the existing conditions,we should try to reduce the water use design planning near the outlets with high indexes,scientifically reduce wastewater discharge,and control wastewater output from the source. In recent years,Peking University has invested a lot of human and material resources in the landscape water environment protection of Yanyuan campus, implemented the project of Weiming Lake management,transformed the water body of Weiming Lake area into self circulation,and dredged the silt;rebuilt the ecological landscape of Houhu Lake area by the dredging of Houhu Lake area on the north side of Weiming Lake;and implemented the cleaning of Weixiuyuan Lake area outside the west university gate. The irrigation of the whole lake area has been realized by silting transformation. The water environment protection work in the Yanyuan campus of Peking University provides support for building a comfortable and peaceful campus environment,and provides guarantee for Peking University to enter the world-class military university and cultivate world-class talents.
