当前,城市排水及水治理形势严峻。一是清洁的地表饮用水匮乏,导致过度开采地下水,由此而产生部分地表的塌陷事故多发。二是由于地表水污染,引起了农田灌溉的土地大面积污染,致使种植业、养殖业受损严重。三是由于城市的快速发展,现有给排水规划和设施落后,造成大量雨水成灾和浪费。四是由于城市的快速发展,生活垃圾与建筑垃圾的分类规范、实施的不到位,形成了循环污染。五是由于各种食物都不同程度地受到了污染,面临食品安全与潜在疾病风险。如何综合治理?本文试作一些探索。
At present, the situation of urban drainage and water management is grim. First, lack of clean drinking water on the ground, resulting in over-exploitation of groundwater, resulting in some surface subsidence accidents occur frequently. The second is due to surface water pollution, causing a large area of farmland irrigation land pollution, resulting in serious damage to farming, aquaculture. Third, due to the rapid development of cities, the existing water supply and drainage planning and facilities are backward, causing a great deal of rain disaster and waste. Fourth, due to the rapid development of the city, the classification of domestic waste and construction waste is not standardized and circular pollution has been formed. Fifth, due to the varying degrees of contamination of various foods, they are at risk of food safety and potential diseases. How to deal with it comprehensively?
