底泥疏浚对城市浅水湖泊环境效应的影响

Effects of Sediment Dredging on Environmental Effects of Urban Shallow Lakes

底泥疏浚是控制湖泊内源污染的常用工程手段,但疏浚同时也带来较多的环境问题。本项目以南京月牙湖为研究对象,研究底泥疏浚对富营养化的城市小型浅水湖泊的环境效应,为类似城市富营养化浅水湖泊的治理,提供借鉴。本项目对月牙湖湖水的PH、电导率、透明度、溶解氧、氨氮、总磷、高锰酸盐指数等一系列的理化指标进行了定量检测,根据底泥疏浚前后水环境发生的变化,从而探究底泥疏浚对城市浅水湖泊环境效应的影响。

Sediment dredging is a common engineering method to control the lake's internal pollution,but it also brings many environmental problems.This project takes Nanjing Yueya Lake as the research object to study the environmental effects of sediment dredging on the eutrophic urban small shallow lakes,providing reference for the treatment of similar urban eutrophic shallow lakes.In this project,a series of physical and chemical indexes such as pH,conductivity,transparency,dissolved oxygen,ammonia nitrogen,total phosphorus and permanganate index of Yueya Lake were quantitatively detected,and the impact of sediment dredging on the environmental effects of urban shallow lakes was explored according to the changes of water environment before and after sediment dredging.
