中文拼音 [jiěchúxùníng]
解除絮凝
英文
deflocculation-
Study on the enhanced flocculation of the natural humus by polydiallyldimethylammonium chloride
陽離子聚電解質強化絮凝去除活性染料的研究Removal of dissolved organic matter by chemical - biological flocculation process
化學生物絮凝工藝對溶解性有機物的去除特性The output signal of pda is affected by the suspended particle concentration, particle size, and the type and dosage of coagulant as well. by analysing the fi curve, it is found that the characteristic parameters of fi curve closely relate to aggregates size and turbidity removal the aggregates size and turbidity removal achieve the maximum when the amplitude of fluctuation is the maximum. the mean diameter and fractal dimension increase with agitation time, and finally reach a steady - state
通過對混凝過程的在線監測和對pda輸出信號fi曲線的數學解析表明: fi曲線綜合反映了懸濁液中膠體顆粒濃度和顆粒粒徑,混凝劑種類和投量很大程度上影響了fi曲線形狀, fi曲線的特徵值與絮凝體平均粒徑和濁度去除率之間具有良好的相關關系,在振幅最大處,濁度去除率達到最高,絮體平均粒徑最大,該條件下對應的投藥量為最佳投藥量。During the tour, the visiting party was given first - hand information about the computer control system of the plant, and the operation of the flocculation and sedimentation tanks, the sludge dewatering house and the chemical dosing facilities
區議會成員在這次參觀中除聽取有關污水廠的電腦控製程序的最新資料外,同時亦參觀絮凝池及沉澱池、污泥脫水設施及化學劑調控中心,了解這些設施的運作情況。The main conclusion are as bwlow : 1. for microflocilation / uf progress, ferric salts were better than aluminum salts ; the more dose of coagulant, the high removal rate of organic matter. however when dose increased to a certain level ( 6mg / l alo2 ), fouling was higher instead
主要成果和結論如下: 1 .微絮凝-超濾工藝中,鐵鹽混凝劑比鋁鹽要好;隨著混凝劑投加量的增加,有機物的去除率也隨著增加,但當混凝劑投加量增加到一定量(以al2o3計為6mg / l )時,反而會加劇膜污染;投加pam (聚丙烯酰胺)對提高有機物去除率沒有幫助,但可以緩解膜污染。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
