水对于人类生活和国民经济发展都至关重要。水资源短缺的状况已引起人们的关注。许多地区都以地表水作为生活饮用水及工业用水水源。而地表水的特征一般是浑浊度高并容易受到一定程度的污染。这就需要进行净化处理使之达到生活饮用水或工业用水标准。对于工业废水、生活污水也需经处理达到允许排放的要求。要做好水处理,选择合适的混凝剂是净水技术中的首要环节。几年来的实践证明:用聚合硫酸铁处理黄河水,可使出水水质符合国家生活饮用水卫生标准。
Water is vital to human life and national economic development. The shortage of water resources has drawn people’s attention. In many areas, surface water is used as a source of domestic drinking water and industrial water. The characteristics of surface water are generally high turbidity and susceptible to a certain degree of pollution. This requires purification to bring it to domestic drinking water or industrial water standards. For industrial wastewater, domestic sewage needs to be treated to meet the emission allowance requirements. To do water treatment, select the right coagulant water purification technology is the first link. Practice over the past few years proved that: Polyferric sulfate treatment of the Yellow River water, water quality can be consistent with the national drinking water health standards.
