随着工农业发展以及城镇化进程的加快,我国水环境形势日趋严峻,集中体现在水少、水脏两个方面。资源性缺水、水质性缺水与工程性缺水加剧水资源的供求矛盾;地表水、地下水与饮用水污染在制约经济社会前迚的同时也威胁着人体健康。我国缺水现象严重,水荒压力与日俱增。此外,水污染严重是我国水环境面临的另一挑战。我国地表水、地下水均有不同程度的污染,地下水污染情冴尤为严重。受地表水、地下水污染影响,饮用水水源地也存在污染物超标现象,我国水污染 With the development of industry and agriculture and the acceleration of the process of urbanization, the situation of water environment in our country is becoming more and more severe, with concentrated expression in two areas: water shortage and water pollution. Water resources shortage, water quality and engineering lack of water aggravate the contradiction between supply and demand of water resources. Surface water, groundwater and drinking water pollution threaten human health while restricting economic and social development. Severe water shortages in China, increasing pressure on water shortage. In addition, serious water pollution is another challenge that China’s water environment faces. Surface water and groundwater in our country all have different degrees of pollution, and groundwater pollution is particularly serious. Affected by the surface water and groundwater pollution, drinking water sources also exist excessive pollutants phenomenon, China’s water pollution
