傍河水源地一般具有水量丰富、水的矿化度低、造价便宜等优点。尽管它有产生淤塞的可能性,但在城市、厂矿供水中还是被广泛采用。然而地表水体(例如河流)既是水源地可靠的、稳定的补给源,又往往是工业废水、污水的排泄场所。随着生产的发展,人民生活水平的提高,未净化或净化得不够的废水、污水的排放量大大增加,使地表水体受到不同程度的污染,因而也污染了 Riverside sources generally have abundant water, low salinity of water, and low cost. Despite its potential for silting, it is still widely used in the supply of water to factories and mines in urban areas. However, surface water (such as rivers) is not only a reliable and stable supply source of water but also a place where industrial wastewater and sewage are drained. With the development of production, improvement of people’s living standards, and the unpurified or insufficiently-purified wastewater, the discharge of sewage water greatly increases, which pollutes surface water bodies to varying degrees
