  1. By making some assumptions, collision frequency were presented. then the the flocculation kinetics model was established through population balance equation. comparison of experimental data and modeling results indicate that there are the same trend between the two. so the model can predict floes number and size during flocculation of yellow river ' s loess particles without using empirical parameters. the tem and sem were used to obsever floes in the study of floe structure. the flocculation was divided as flocculi, floc and floe aggregate. the floes structure model was established by assumption that particles position in floe accords with tetrahedron. the fractal dimension of model and experimental floes was found to be coincidentso the model can reflect the structure of flocs formed in flocculation of yellow river ' s loess particles by macromolecule flocculant at a certain extent

    最後,本文還對絮凝動力學和絮體結構進行了研究,在前人研究基礎上,針對高分子絮凝黃河泥沙,對絮凝過程作了一些符合試驗條件假設,建立了顆碰撞頻表達式,應用了顆數量平衡方程,從而建立了絮凝過程動力學生長模型,模型計算結果與試驗數據對,二者趨勢一致,在沒有使用經驗參數情況下基本上能夠描述黃河泥沙絮凝過程中絮體數量和尺寸分佈變化過程;對絮體結構研究中,應用掃描電子顯微鏡和射電子顯微鏡對絮體進行了觀察,將絮體分為絮、絮團和絮網三個不同生長階段,通過假設顆結合位置符西安建築科技大學博士學位論文合正四面體,建立了絮體結構模型,計算得到模型絮體分形維數基本與試驗中實際絮體相符,在一定程度上能夠反映高分子絮凝黃河泥沙生成絮體結構。
  2. 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

    應用脈動檢測技術和光散射顆度分析儀( pda ) ,通過理論分析,將pda輸出信號之一? ?平均光強度(對應于dc值)作為原水特性表徵參數, dc值可以同時反映顆濃度和表面積因素影響,試驗結果證, dc值與單位體積水中泥沙顆總表面積s _ p之間具有很好冪函數關系: 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 ,利用所建立公式,建立了前饋? ?后饋聯合控制在線自動投藥模型。
