摘　　要：针对某水库原水 ,通过中试试验结合理论分析 ,对SCD自动控制加药技术用于微絮凝过滤作了较为系统的分析和研究。试验结果表明 :某水库水在一般情况下 (原水浊度小于 2 0NTU) ,流动电流设定值SP应为 - 17 5。The application of SCD controlled chemical dosage for micro-coagulant filtration process was researched systematically by pilot plant experiment and theoretical discussion on raw water of a reservoir. The experimen t results show that in general condition, i.e. raw water of reservoir with turbidity no more than 20 NTU the streaming current set point (SP) should be -1 7.5. Finally the authors point out that the SCD controlled coagulant dosage is practical for micro-flocculation filtration of raw water from reservo ir source.
