再生水补给的景观河道水质与富营养化状态评价

Recyded water quality in landscape rivers and eutrophication status assessment

为了更好地管理天津开发区东区景观河道,本文对该河道2018年3月至2019年2月的水质情况进行了监测,依据监测数据对其水质及黑臭等级进行了评价,并应用综合营养指数法进行营养化状态评价。结果显示,该景观河道不属于黑臭水体,但全年处于富营养化状态。建议采取清淤、适当再生水补水、种植多样水生植物等措施来改善河道水质,减少其富营养化状况。

In order to better manage the landscape river course in the eastern district of Tianjin Economic-Technological area,this paper monitored the water quality of the river course from March 2018 to February 2019. According to the monitoring data,the water quality and black odor grade were evaluated,and the comprehensive nutrition index method was used to evaluate the nutritional status. The results show that the landscape river is not a black and odorous water body,but it is in a state of eutrophication all year round. It is suggested that desalting,appropriate reclaimed water supplement and planting various aquatic plants should be taken to improve the river water quality and reduce its eutrophication.
