Traceability and response method of sudden water pollution events in typical riverside areasEI北大核心CSCD

针对城市内河突发水污染事件频发引起水资源及经济的巨大损失,提出了Hartree闭环河湖水质预警法,通过事件发生、溯源追踪、预警排查、预测分析、应急处理及恢复原状的处置流程,采取监测预警、水质巡测、河长App、模型预测、紧急抢修及警报解除的措施,提出了基于水污染溯源的快速响应及事故处理方法。以南京金川河水系为例,研究了水污染突发事件后污染物的溯源、响应及事故处理的流程,基于耦合模型计算,通过有无Hartree闭环河湖水质预警法和不同调水量浓度场对比,得到调水量与水质超标时长的相关关系,从方法效用上提高了处理该类事件的效率。

Traceability and response method of sudden water pollution events in typical riverside areas

In view of the huge losses of water resources and economy caused by the frequent occurrence of sudden water pollution events in urban rivers, Hartree closed-loop river and lake water quality early warning method is proposed. Through the disposal process of incident occurrence, traceability, early warning and investigation, prediction and analysis, emergency treatment and restoration, and implementing the measures of monitoring and early warning, water quality inspection, river chief App, model prediction, emergency repair and alarm relief, a fast response and accident handling method based on water pollution traceability is proposed. Taking the Jinchuan River system in Nanjing as an example, the process of pollutant tracing, response and accident treatment after water pollution emergencies is studied. Based on the calculation of the coupling model, the correlation between the quantity of water transferred and the duration of water quality exceeding the standard is obtained through the comparison of the concentration fields of different water transferred quantities with or without using the Hartree closed-loop river and lake water quality early warning method. The efficiency of handling such events is improved from the perspective of method utility.
