面对泉城济南水环境恶化,泉水时断时涌、甚至断流干涸的趋势,分析了济南泉水的来源路径,认为地下水的超量无序开采、河川径流及大气降水对泉域水系统的补给量减少是泉水停喷的根本原因。基于水环境恢复原理理论,认为必须建立崭新的用水模式,建立健康的社会水循环是解决水环境问题的正确出路;同时提出水健康循环方略有:节制用水、污水深度处理和有效利用、污水厂污泥回归农田、恢复城市雨水循环途径、面源污染控制以及水资源统筹管理等。其中,修复城市雨水循环、污水深度处理和有效回用、节制用水是济南市水环境恢复、实施“保泉”工程的切入点。
Faced with the deteriorating water environment in Jinan and the trend of the spring water flowing intermittently and intermittently, the source of Jinan springs was analyzed. It was concluded that the excessively disorderly exploitation of groundwater, the runoff of the rivers and the recharge of the precipitation to the spring water system The decrease is the root cause of spring stop spraying. Based on the principle of water environment restoration, it is considered that a brand-new water use pattern must be established and a healthy social water cycle is the correct way to solve the water environment problem. At the same time, some water circulation strategies are proposed: control water, advanced wastewater treatment and effective utilization, Mud back to farmland, restoration of urban rainwater recycling, non-point source pollution control and integrated management of water resources. Among them, the repair of urban rainwater recycling, sewage treatment and efficient reuse, water control is Jinan City, water environment recovery, the implementation of “Baoquan ” project entry point.
