Abstract:In order to further improve the water quality of the state-controlled section in the lower reaches of Youshui River and ensure the stability of reaching the standard,this paper takes the upper reaches of the state-controlled section of Youshui River as the research object,uses the fluorescence fingerprinting method to trace the pollution in the basin,and samples from two rivers and coastal sewage treatment plants in the upper reaches of Youshui River are sampled and moni-tored to identify and judge the main factors and sources affecting the water quality in the lower reaches of the state-controlled section,so as to provide reference for water quality control in the basin.The results show that the water quality of Youshui River and Guoli River basins is in Grade Ⅲ or above,the concentration of pollutants in the samples of four coastal sewage treatment plants is significantly higher than that of surface water,and the level of metal elements in the water bodies in the basins is low.The influence of Youshui River on the downstream state-controlled section is higher than that of Guoli River.The main source of the influence of Youshui River is the drainage of Luositan sewage treatment plant along the coast,and the main reason of the influence of Guoli River is the industrial park sewage treatment plant.It is suggested that,on the one hand,continuous attention should be paid to the drainage quality of sewage treatment plants,and on the other hand,the phenomenon of agricultural non-point sources and rural domestic sewage scattered along the coast should be investigated and rectified.
