摘要
用高梯度磁分离技术处理给水，通常在投加Ｆｅ３Ｏ４铁粉及混凝剂时可以去除水中的细菌。细菌总数和大肠杆菌的去除率均可达到９９％．通过试验证明，未经处理的松花江水和深井水直接通过高梯度磁滤器，不投加Ｆｅ３Ｏ４铁粉和混凝剂，可以去除水中的细菌和大肠杆菌，去除率在９０％以上．
It has been proved that when Fe3O4 magnetic powder and coagulant were put in the raw water to be treated with technique of high gradient magnetic filter, the bacteria in the water might be removed. The removal efficiency of the total amout either of bacteria or of colon bacilli might reach above 99%.However, authors consider that the raw water without being added Fe3O4 magnetic powder and coagulant, the bacteria in the water may also be removed with high gradient magnetic filter. The experiment proves that when the untreated water in Songhua River and deep well water were passed through the high gradient magnetic filter, the bacteria and colon bacilli were also removed. The removal efficiency was above 90%.
