金昌 洗煤厂 聚丙稀铣胺 PAC 聚合

  阳离子聚酰胺使用注意事项：
1、絮团的大小：絮团太小会影响排水的速度，絮团太大会使絮团约束较多水而降低泥饼干度。经过选择聚酰胺的分子量能够调整絮团的大小。
2、污泥特性。**点理解污泥的来源，特性以及成分，所占比重。依据性质的不同，污泥可分为**和无机污泥两种。阳离子聚酰胺用于处置**污泥，相对的阴离子聚酰胺絮凝剂用于无机污泥，碱性很强时用阳离子聚酰胺，而酸性很强时不宜用阴离子聚酰胺，固含量高时污泥通常聚酰胺的用量也大。
3、絮团强度：絮团在剪切作用下应坚持稳定而不破碎。进步聚酰胺分子量或者选择适宜的分子构造有助于进步絮团稳定性。



Precautions for use of cationic polyacrylamide:

1. Size of floc: too small floc will affect the drainage speed. Too large floc will restrict more water and reduce the degree of mud biscuit. After selecting the molecular weight of polyacrylamide, the size of floc can be adjusted.

2. Sludge characteristics. The first point is to understand the source, characteristics, composition and proportion of sludge. According to different properties, sludge can be divided into organic and inorganic sludge. Cationic polyacrylamide is used to dispose organic sludge, while anionic polyacrylamide flocculant is used for inorganic sludge. Cationic polyacrylamide is used when the alkalinity is very strong, but anionic polyacrylamide is not suitable when the acidity is very strong. When the solid content is high, the amount of polyacrylamide is usually large.

3. Floc strength: floc shall be stable and not broken under shear. Improving the molecular weight of polyacrylamide or selecting appropriate molecular structure is helpful to improve the stability of flocs
