Mike Hydro River软件在龙王港水污染治理中的应用
|
摘要
采用Mike Hydro River软件对龙王港水质进行了模拟,分析了截污纳管和生态修复两种治理方案下,龙王港水质COD_(cr)、TP、TN等参数空间变化,全年COD_(cr)、TN水质参数变化,指出河流现状水质较差,采取截污纳管治理措施后,水质可达到V类水要求;采取截污纳管和生态修复治理措施后,水质可达到Ⅳ类水要求,为工程实施提供指导依据。
In this paper, the water quality of Dragon King Port River was simulated by utilizing Mike Hydro River software. The spatial water quality changes of COD_(cr), TP, TN and other parameters in Dragon King Port River and the annual water quality changes of COD_(cr), TN in the lower reaches of Dragon King Port River were analyzed under two treatment schemes of Sewerage Interception and Ecological Remediation. We pointed out that the current water quality in all of periods of this river was lower V of Environmental Quality Standard for Surface Water(EQSSW), and It could be reached the Standard V after actualizing the treatment of Sewerage Interception; The water quality could reach the Standard IV after taking the measures of Sewerage Interception and Ecological Remediation,which support guidance for the implementation of the project.
