基于质谱联合三维荧光法的小流域水体中有机污染物溯源

A Source Tracing Study on Organic Pollutants in Water Bodies of Small Watersheds Based on Mass Spectrometry Combined with Three-Dimensional Fluorescence Method

为了对河流污染物精准溯源,提出基于质谱联合三维荧光法的水体中有机污染物预警溯源方法,以G河为例,根据研究水体实际情况设置采样点,获取水体样本,确定主要污染物、污染类型及污染传输路径。研究发现,G河存在种植、养殖和工业的复合污染,Z1以农业种植污染为主,Z2以生活污水污染为主,Z3以生活污水和农业种植污染为主,Z4以养殖废水污染为主,Z5和Z7均是以农业种植废水、养殖废水和生活污水的复合污染,Z6上的工业园区是G河工业废水污染的主要输入源。

In order to accurately trace pollutants in a river,an early warning traceability method for organic pollutants in water bodies was proposed based on mass spectrometry combined with three-dimensionalfluorescence method,and sampling spots were set up according to the actual situation of the water bodies under study for identifying key pollutants,types of pollution and pollutant transmission paths.It has been found that there are compound pollution of cultivation,breeding and industry in the River G.It is mainly polluted by agricultural planting at Z1,by domestic wastewater at Z2,by both domestic wastewater and agricultural planting at Z3,by rearing wastewater at Z4,and by compound pollution of agricultural planting,rearing wastewater and domestic wastewater at both Z5 and Z7,whilst main source of industrial wastewater pollution is from an industrial park at Z6 of the River G.
