  3. 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

    應用透光率脈動檢測技術和光散射顆粒粒度分析儀（ pda ） ，通過理論分析，將pda的輸出信號之一? ?平均透光強度（對應于dc值）作為原水的特性表徵參數， dc值可以同時反映顆粒濃度和比表面積因素的影響，試驗結果證明， dc值與單位體積水中泥沙顆粒總表面積s _ p之間具有很好的冪函數關系： dc = cs _ p ~ d ，式中c 、 d為經驗系數，進而得到了以dc值為參數的高分子絮凝劑投藥量公式： d = f （ dc ） = e （ dc ） ~ f ，式中： e 、 f為經驗系數，平均相關系數達0 . 981 ，利用所建立的公式，建立了前饋? ?后饋聯合控制的在線自動投藥模型。
