基于WASP对渝河NH_3-N排放方案的研究

随着宁夏南部山区经济的快速发展,水环境问题在渝河表现得尤为突出。为实现"建设美丽宁夏"和"渝河出境水质达到Ⅳ类标准"的目标,对渝河排污的控制极为重要。因此,基于2014年渝河的监测资料,运用WASP建立一维水质模型对渝河污染主因子NH_3-N排放方案进行研究,并提出了相应的水环境保护建议。结果表明:当初始隆德断面为Ⅲ类水质标准,NH_3-N按一级A标准的优化方案进行排放时,可以达到出境水质目标;同时,增设监测断面ZG1和ZG2有利于全面反映渝河水质的沿程变化。

STUDY ON NH3-N EMISSION SCHEME OF YU RIVER BASED ON WASP MODEL

With the rapid development of economy in the southern mountainous area of Ningxia,the water environment problems are becoming more and more serious,especially in Yu River.In order to achieve the construction of “ Beautiful Ningxia” and the target of “ the IV Criterion Boundary Water Quality”,the control of Yu River pollution is extremely important.Therefore,based on the monitoring data of Yu River in 2014,we used WASP to establish a one-dimensional water quality model to study the main pollution factors of the NH3-N emission scheme,and put forward some corresponding water environment protection suggestions.The conclusion was as follows:When the initial Longde section complied to the Ⅲ criterion of water quality,and NH3-N was discharged according to the optimization scheme of the first level A standard,the water quality objective could be achieved;the addition monitoring section of ZG1 and ZG2 was beneficial to reflect the variation of the water quality along the river.
