絮化作用 的英文怎麼說
中文拼音 [xùhuàzuòyòng]
絮化作用
英文
flocculation-
Alkaline detergents are effective for emulsification and deflocculation
堿性去污劑具備有效的乳化和反絮凝作用。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。Sodium metasilicate has strong alkalinity and good buffering capacity. it can neutralize acidic dirt, emulsify grease and oil, and provide corrosion proofing to metals. it is a basic material for the detergent industry, widely used in domesticindustrial detergent, food cleaner, metal cleaner, washing carbonated drink bottles, printing aid for textile, deinking recycled paper, etc
偏硅酸鈉具有強堿性，去污力強，緩沖能力大，可中和酸性污物，使脂肪和油類乳化，對無機物有反絮凝作用，對金屬有防腐蝕作用，是洗滌業不可替代的原料，廣泛應用於家庭洗衣粉、工業洗滌劑、食品清洗劑、金屬清洗劑、酒瓶清洗劑、除油紡織印染助劑及紙張脫墨劑等。The prepn. of dimethyldiallylammonium chloride monomer and the related polymers was summarized, and the use of the derivatives in text, dyeing and printing as antistatic, color fixing and flocculating agents were presented
摘要簡述了二甲基二烯丙基氯化銨單體及其相關聚合物的制備方法，介紹了聚二甲基二烯丙基氯化銨及其衍生物產品在紡織印染行業中作為抗靜電劑、固色劑和絮凝劑的應用。Wastewater treatment plants - chemical treatment - treatment of wastewater by precipitation flocculation
廢水處理廠.化學處理.通過沉澱作用絮凝作用處理廢水Wastewater treatment plants - part 13 : chemical treatment - treatment of wastewater by precipitation flocculation
廢水處理廠.第13部分:化學處理.通過沉澱絮凝作用處理廢水The mean diameter increases with the increase of alum dose, but the fractal dimension does not vary. however, extremely high dose of sluminum results in an increase of floc diameter but a decrease of the fractal dimension. the main reason is the sweep floes is too loose in their structure, and ca n ' t resist the shear force
隨著投藥量的增大，絮凝體分形維數的變化較小，但絮凝體平均粒徑顯著增加；當投藥量過高時，網掃絮凝作用下的絮體結構鬆散，抗剪切能力差，具有較小的平均粒徑和分形維數。Synergistic pollutant removal action in the pre - suspended carrier bed - chemical and biological flocculation process
前置懸浮填料床化學生物絮凝工藝對污染物的協同去除作用There are certain theory and practical application for the conclusion developed in this paper. in the first place, the cognition is deepened about colloid flocculation. in the second place, it can be used to improve the coagulation process for sewage containing cationic surfactants
本文對陽離子表面活性劑作用下膠體顆粒的混凝機理進行研究，對加深有關膠體絮凝理論的認識，優化陽離子表面活性劑微污染情況下絮凝工藝具有重要意義。Online monitoring of the coagulation process by pda2000 shows that flocculation index is fairly consistent with the removal of toc, the bigger the fi, the higher the toc removal. in this paper, preliminary study on floc structure is also reported. it is found that various coagulation conditions lead to different floc structures
在混凝過程中利用pda2000進行光學在線監測，充分表明其輸出信號fi指數與toc去除率之間具有很好的相關性， fi指數越大， toc去除率越好，並且通過對fi指數的解析，可看出其對混凝過程及絮體的變化具有很靈敏的表徵作用。分享友人
