海绵城市河道水处理措施应用效果浅析

Brief analysis of Application Effect under River Water Treatment in Sponge City

河道治理作为海绵城市建设中的重要内容之一,因其受季节变化、行洪排涝、内外源污染的影响而成为建设实施中的难点。而对其治理范围的有效选择,外因要素的合理把握,分析工具的科学使用将成为该项目能否成功实施和研究借鉴的基础和关键。本项目选择了污染程度较低、水力连通性较强的两条主城区内垂直交叉的二级河道作为研究对象。通过对该河道多年水质数据的筛选和分析,并针对其特点使用生物制剂与生物设施相结合的治理路线,有效地在该项目成功建设并运营实施一年后对此河道的水质进行了明显的改善和提升,并同时满足了其既定的水质标准的要求。这不仅为其他类似项目的建设提供了重要的参考依据,也为该地区海绵城市内容的系统性实施完善了必备的环节。

River regulation work is one of the important contents in the construction of Sponge City and it becomes the bottleneck in construction and implementation due to the influences of seasonal changes,flood drainage,internal and external source pollution.While the effective selection of its regulation range,reasonable control of its external factors,the scientific use of its analysis tools will become the basis and key factors for successful implementation and research reference.This project selected two vertical-crossing secondary rivers in the main urban area with low pollution and strong hydraulic connectivity as the object of study,and effectively improved and upgraded the water quality of the river with meeting the design requirements of its water quality standards in the meantime after its successful construction and one year operation through the selection and analysis of the water quality data of the river for some years with the joint application of biologics and biological equipments according to its characteristics.Therefore,it is not only provides an important reference for the construction of other similar projects,but also integrates the compulsory part for the systematic implementation of the Sponge City in this region.
