flocs 解釋
絮凝體
  1. Spectrum analysis of flocs diameter in the changjiang estuary

    長江河口細顆粒泥沙絮凝體粒徑的譜分析
  2. Dla simulation of fractal flocs and calculation of fractal dimension

    分形模擬及其分形維數的計算方法
  3. Causes and countermeasures of flocs floating occurred in inclined tube sedimentation tank

    斜管沉澱池絮體上浮成因及對策
  4. 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，在前人研究的基礎上，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的假設，建立了顆粒碰撞頻率表達式，應用了顆粒數量平衡方程，從而建立了絮凝過程的動力學生長模型，模型計算結果與試驗數據對比表明，二者趨勢一致，在沒有使用經驗參數的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的變化過程；對絮體結構的研究中，應用掃描電子顯微鏡和透射電子顯微鏡對絮體進行了觀察，將絮體分為絮粒、絮團和絮網三個不同的生長階段，通過假設顆粒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，計算得到的模型絮體分形維數基本與試驗中的實際絮體相符，在一定程度上能夠反映高分子絮凝黃河泥沙生成的絮體結構。
  5. By designing some static flocculation experiments during different flocculating agent and different flocculating condition, the modal characteristic of floes are observed in experimented process and microscope photo of floes are shot. afterwards fractal dimensions of floes are calculated according to microscope photo of floes. the experimental result suggested that fractal dimensions of flocs are 1. 31 - 2. 38 during different flocculating condition when the flocculating agent is aluminum sulfate

    當pac投加量為5 . omg / l並採用caci :為助凝劑時，若先投加pac再投加cacb ，混凝效果最好的水樣的絮凝體的分形維數為2 . 43 ，化學需氧量去除率94 . 7 % ，此時的cacb投加量為1 . 5m留飛。
  6. In clay - humic acid suspension, the coagulation is subject to the organics. the presence of clay particles improves the settle ability of flocs

    無機顆粒的存在可提高有機物絮體的沉降性，減小toc和doc之間的差別，促進有機物的去除。
  7. This paper mainly studied the coagulation characteristics of natural organic matters ( nom ), analyzed the impact of inorganic particles on coagulation mechanisms and effects of nom. online monitoring of the coagulation process was conducted by using pda2000 and the structure of flocs was preliminary discussed

    本文主要研究了水中天然有機物的混凝特性，同時分析了無機顆粒對有機物混凝機理及效果的影響，並通過pda2000對混凝過程進行光學在線監測，初步探討了絮體結構。
