混凝形態學就是從水中膠體顆粒和所加混凝劑在水中的真實形狀和大小,以及由它們形成的絮凝體真實結構出發來研究整個混凝過程的一門較高層次的學科。The results showed that the rubber latex particles separated the clay into nanometer units, accompanied with the competition between separation of rubber latex particles and re - aggregation of single silicate layers upon addition of flocculant during the process of co - coagulating, while the intercalation of rubber molecules into clay galleries did not occur
結果表明,在加入絮凝劑使橡膠乳液黏土水懸浮液共凝聚的過程中,由於存在膠乳粒子對黏土片層的隔離作用與在混合液中分散的黏土單片層的重新聚集作用的競爭,因此,在絮凝物中,橡膠大分子將黏土片層隔離成納米分散單元(包括單片層和多片層的聚集體) ,在多片層的黏土聚集體層間沒有橡膠大分子插入。Because of the influences of the turbidity, ph of raw water, current, temperature and the pollutions of raw water, the process of coagulant dosage is a very complex reaction. to find out the automation of coagulant dosage and reduce the cost of the coagulant, many domestic and international scientific research organizations make research into the theory and mechanism of automation of coagulant dosage, such as the streaming current control method ( scd ), the emulation experimenting method in spot, mathematics model, flocculation control device ( fcd )
由於受到原水濁度、 ph值、配水流量、原水溫度和其他水質污染的影響,投藥絮凝過程是一個非常復雜的反應過程,為實現投藥系統的自動化和降低混凝劑耗率,國內外相當多的科研機構和院校在進行投藥機理和自動化處理的研究,主要有流動電流儀檢測法( scd ) 、現場模擬實驗法、數學模型、顯示絮凝控製法( fcd法)等自動投藥方式的研究和實驗。Abstract : the recent development of coagulants and flocculent wa s reviewed. three topics were discussed : ( 1 ) mechanisms of coagulants and flocculen t, and the experimental methods of process study ; ( 2 ) development of coagulants and flocculent ; ( 3 ) researches on improvement of coagulants and flocculent efficiency, process optimization and on - line monitoring and controlling as well

雖然實際混凝過程沒有嚴格區分,但試驗證明了無機絮凝劑的混合和凝聚幾乎是在同一階段完成,並且要求較弱的攪拌強度。Experimental researches on paint wastewater treatment the application of coagulation - flocculation and oxidation - flocculation reactor technique
混凝沉澱和氧化絮凝復合床法的應用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。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。This paper introduces the reasons of the chroma of coking wastewater in the biochemical process, probes into how to eliminate the chroma from the adsorption and flocculation, and puts forward some tactics that should be adopted in the decolorization of coking wastewater through the coagulation
