报导了净水过程中使用计算机实时采集和定量分析絮凝池中絮体图像，算出絮体沉淀“等效直径”作为控制混凝剂加注率的目标值，并用进水流量和沉淀水浊度信号自动修正目标设定值。加注量为进水流量与加注率之积。实验数据表明，该方法能适应水质和其他因素的变化自动调整加注量，达到了稳定沉淀水浊度的目的。
The paper reports the real-time acquisition and quantitative analysis of the flocculation flocculant image in the process of water purification, and calculates the “equivalent diameter” of floc precipitation as the target value for controlling the pouring rate of the flocculant, and uses the influent flow rate and the sediment turbidity The signal automatically corrects the target setting. Filling volume is the product of inflow rate and filling rate. The experimental data show that this method can automatically adjust the filling amount to adapt to the changes of water quality and other factors and achieve the purpose of stabilizing the turbidity of precipitation water.
