摘要
为进一步提升酉水河下游国控断面水质,保障稳定达标,该文以酉水河国控断面上游为研究对象,利用水质荧光指纹法开展流域污染溯源,对酉水河上游2条河流及沿岸污水处理厂的样品进行采样监测,识别判断影响下游国控断面水质的主要因素与来源。结果表明,酉水河及果利河流域水质处于Ⅲ类及以上水质,沿岸4处污水处理厂样品污染物浓度水平显著高于地表水,流域内水体金属元素水平均较低,酉水河对下游国控断面的影响高于果利河,酉水河产生影响的主要来源为沿岸的螺蛳滩污水处理厂排水,果利河产生影响的原因主要为工业园污水处理厂。建议一方面持续关注污水处理厂的排水水质,另一方面对沿岸的农业面源及农村生活污水散排现象进行排查整治。
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 monitored 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 GradeⅢor 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.
