摘要
分析了河道黑臭水体的形成、底泥恶化的成因,并对辉山明渠水体底泥污染情况进行调查和研究,建立底泥各指标因子对流域水环境黑臭的预警体系,掌控流域底泥的现行状况以及重要指标的变化趋势,为监管部门提供更有效的监管依据,能够防范重大黑臭水体的产生,为保持流域水环境的生态功能和提高人居生活环境提供有效的技术支撑。
The formation of the black and odorous water body in the river channel and the cause of deterioration of t sediment are analyzed,and then the sediment pollution in the Huishan open channel is investigated and studied.The early warning system of indicator factors of sediment for monitoring black-odor situation of the river basin is established,the current status of river basin sediment and the changing trends of important indicators are obtained,which can provide a more effective regulatory basis for the regulatory authorities,also can prevent the generation of major black and odorous water body,and provide effective technical support for maintaining the ecological functions of the river basin water environment and improving the living environment.
