泾河干流(陕西段)水污染现状及控制对策研究
|
摘要
在大量现场监测数据的基础上,利用标准比照法分析泾河流域(陕西段)的水质现状,并采用断面水质类比法,对泾河流域陕西段的水质进行分级评价.结果表明干流水质由2013年、2014年的轻度污染提高为2015年的良好水质逐年好转.支流三水河水质良好,泔河水质最差,为劣Ⅴ类水质.黑河水质大部分指标满足Ⅲ类水质.分析水污染产生的原因,并以"东庄水库"重大课题为契机,针对泾河流域现有污染,提出了近期和远期分期治理方案.
In this paper,based on a large number of on-site monitoring data,the water quality status of Jinghe river basin(Shaanxi section) is analyzed by using the standard comparison method,and the water quality of Shaanxi section of Jinghe river basin is graded and evaluated by using the cross-section water quality analogy method.The results show that the water quality of the main stream has increased from mild pollution in 2013 and 2014 to good water quality in2015.The tributary of Sanshui river has good water quality,and Ganhe river has the worst water quality,which is inferior to class Ⅴ water quality.Most of the water quality indexes of Heihe river meet the requirements of class Ⅲ water quality.Based on the analysis of the causes of water pollution and taking the important project of Dongzhuang reservoir as an opportunity,the short-term and long-term phased treatment is proposed according to the existing pollution in Jinghe river basin.
