摘　　要：在水厂现场,以流动电流为主线对净水工艺进行了分析。结果显示,流动电流对混凝和滤床过滤的运行工况有类似的决定作用,加药混合之后胶体颗粒的流动电流值不再随后续工艺而有大的变化,因此投加混凝剂保持混凝单元操作的最佳状况,也有利于过滤单元的运行。In a water plant, streaming current was monitored along water treatment process chain. The results showed that streaming current had a similar influence on deciding the working efficiency of coagulation and filtration. The streaming current value was not varied largely in the subsequent process of sedimentation and filtration. Thus keeping the optimum dosage in coagulation and flocculation would also be in favor of filtration.
