摘　　要：透光率脉动混凝投药控制技术应用于常规浊度水处理中仍存在着许多不完善的地方 ,尤其原水浊度对以R值为控制参数的控制系统具有极大的不利影响。为此 ,对常规浊度水进行了大量的试验研究 ,提出以 β值为控制系统的控制参数来控制混凝剂的投加 ,并通过试验证明 β值与混凝剂投加量、沉后水浊度之间存在着良好的相关性 ,并且对于不同浊度的原水 ,β值与沉后水浊度之间仍存在着一一对应的关系 ,β值有望替代R值控制混凝剂的自动投加。The coagulation dosage control technique based on the impulsive transmitted light still has some incomplete aspects in the routine turbidity water treatment, especially the control system with the R value as main control parameter was extremely effected by the turbidity of raw water. So, on the basis of wide experimental researches on routine turbidity water, β value was introduced to substitute the R value as the control parameter to control coagulation dosage. The experiments had been proved that the β value has good correlated to the coagulation quantity and residual turbidity, and between the β value and residual turbidity, there still is one by one corresponding relationship. So the β value can be hoped to substitute the R value to control coagulation.
