聚丙烯酰胺注意事項

    1、絮團的大?。盒鯃F太小會影響排水的速度，絮團太大會使絮團約束較多水而降低泥餅干度。經(jīng)過選擇聚丙烯酰胺的分子量能夠調(diào)整絮團的大小。

    2、污泥特性： 點理解污泥的來源，特性以及成分，所占比重。依據(jù)性質(zhì)的不同，污泥可分為有機和無機污泥兩種。陽離子聚丙烯酰胺用于處置有機污泥，相對的陰離子聚丙烯酰胺絮凝劑用于無機污泥，堿性很強時用陽離子聚丙烯酰胺，而酸性很強時不宜用陰離子聚丙烯酰胺，固含量高時污泥通常聚丙烯酰胺的用量也大。

    3、絮團強度：絮團在剪切作用下應(yīng)堅持穩(wěn)定而不破碎。進(jìn)步聚丙烯酰胺分子量或者選擇適宜的分子構(gòu)造有助于進(jìn)步絮團穩(wěn)定性。

    4、聚丙烯酰胺的離子度：針對脫水的污泥，可用不同離子度的絮凝劑經(jīng)過先做小試進(jìn)行挑選，選出較佳適宜的聚丙烯酰胺，這樣即能夠獲得較佳絮凝劑效果，又可使加藥量較少，節(jié)約本錢。

    5、聚丙烯酰胺的溶解：溶解良好才能充分發(fā)揮絮凝作用。有時需求加快溶解速度，這時可思索進(jìn)步聚丙烯酰胺溶液的濃度。

1, the size of the floccules: floccules is too small will affect the rate of drainage, floccules is lower the floccules constraints, more water and mud biscuits.After choosing the molecular weight of polyacrylamide can adjust the size of the floccules.
2, sludge characteristics: the first point to understand the sources of the sludge, the characteristics and composition and proportion.According to the properties of the different, the sludge can be divided into two kinds of organic and inorganic sludge.Cationic polyacrylamide used for disposal of organic sludge, relative anionic polyacrylamide flocculant used in sludge, inorganic alkali is very strong in the cationic polyacrylamide, and should not be used when strong acid anionic polyacrylamide, high solid content in sludge usually polyacrylamide dosage is large.
3, the intensity of floccules: floccules under shearing action should be stable and not broken.Progress of polyacrylamide molecular weight or choose the suitable molecular structure helps to progress floccules stability.
Ion degrees: 4, polyacrylamide for dewatering sludge, different ion flocculant are available after pick to do first test, select the best suitable polyacrylamide, which can achieve the best effect of flocculant, and can make the dosage, at least, to save money.
5, polyacrylamide dissolved: dissolve can give full play to good flocculation effect.Sometimes needs to speed up the dissolution rate, when the concentration of a solution of polyacrylamide can think progress.
