  • On the basis of theory analysis , the average transmitted light intensity ( correspond to dc value ) was determined as characteristic parameter of raw water using photoelectric method for monitoring the fluctuation of transmitted light and photometric dispersion analyzer ( pda ) . the dc value was closely related to both particle concentration and surface area of sand clay simultaneously . the experimental results shows that there is an exponential function relation between dc and surface area of sand clay in unit volume water ( sp ) : dc = asbp in which a and b are empirical coefficients . then the formula of macromolecule flocculant dosage is found to be d = f ( dc ) = e ( dc ) f in which e and / are empirical coefficients and the average correlation coefficient equal to 0 . 981 . so the model of automatical control system of water treatment plant was established using the formula
    应用透光率脉动检测技术和光散射颗粒粒度分析仪( pda ) ,通过理论分析,将pda的输出信号之一? ?平均透光强度(对应于dc值)作为原水的特性表征参数, dc值可以同时反映颗粒浓度和比表面积因素的影响,试验结果证明, dc值与单位体积水中泥沙颗粒总表面积s _ p之间具有很好的幂函数关系: dc = cs _ p ~ d ,式中c 、 d为经验系数,进而得到了以dc值为参数的高分子絮凝剂投药量公式: d = f ( dc ) = e ( dc ) ~ f ,式中: e 、 f为经验系数,平均相关系数达0 . 981 ,利用所建立的公式,建立了前馈? ?后馈联合控制的在线自动投药模型。
