混凝剂,絮凝剂,助凝剂您是不是有时候搞不清楚呢?那么今天全天环保的小天来解释下吧?一般来说混凝剂主要指无机絮凝剂,主要是使得被鑫百利国际客服对象脱稳,破乳,包括聚合氯化铝(PAC)、聚合硫酸铁(PFS)。絮凝剂一般指有机的,能加速固体和液体分离的水溶性高分子聚合物通常指的是聚丙烯酰胺。混凝剂、助凝剂事实上指的是絮凝剂。




絮凝剂的分类和品种




1.1 简述常见的几种无机混凝剂的性能和特点

答  常见的无机混凝剂有硫酸铝、聚合氯化铝、三氯化铁、硫酸亚铁等。

硫酸铝  硫酸铝或为固态,或为液态。固态的硫酸铝为片状、粒状或粉状。它的理论分子式为Al2(SO43·18H2O,通常有氧化铝含量,即AlO来表示,其值约为17%。粉状硫酸铝的表观密度在1000kg/m左右。液态硫酸铝与固态一样也是以氧化铝AlO含量来表示的。其浓度通常为8.0%~8.5%,为粉状含量的48%~49%,即每升水溶液含630~650Al2(SO43·18H2O。


硫酸铝用于混凝时,须有适宜的pH值范围。在去色时pH值适宜范围为5~6;在去浊度时,pH值适宜范围在6~8之间。生产上*佳pH值范围一般为6.5~7.5。由于铝的相对密度较小,所以铝盐形成的矾花轻而疏松,特别冬天水温低时,难以结成大、重而易沉的颗粒。


聚合氯化铝聚合氯化铝,又名碱式氯化铝。通常使用液态的,其理论分子式为[Aln(OH)mCl3n-m]效能优于硫酸铝,相同水质下,投加量比硫酸铝少,对pH值的适应范围也较宽,可在5.0~9.0之间。对鑫百利国际客服高浊度水和低温水效果较好,腐蚀性小,投药方便,成本较低。


三氯化铁三氯化铁有固态的和液态的,且多数使用液态的。固态的氯化铁的外观是黄褐色的容易潮解的结晶物质,分子式为FeCl3·6H2O。它的作用机理也与硫酸铝相似,但对pH值的适应范围宽(在6.0~8.4之间),形成的絮凝体比铝盐絮凝体大、重、密实,鑫百利国际客服低温或低浊度水的效果优于硫酸盐。缺点是三氯化铁腐蚀性较强,易吸湿潮解。


硫酸亚铁硫酸亚铁(FeSO4·7H2O)是半透明绿色结晶体,俗称绿矾。使用时受水温影响较小,形成的絮凝体大、重而易沉。较适于浊度高、碱度高和pH值为8.5~9.5的原水。硫酸亚铁用于混凝,会使鑫百利国际客服后的水带色,特别是当Fe2+与水中有色胶体作用后,将生成颜色更深的溶解物,影响水的使用。所以采用硫酸亚铁作混凝剂pH值较低时,常用氯将二阶铁Fe氧化成三阶铁Fe3+。


1.2 如何确定混凝剂的投加顺序

答  混凝剂的投加有无*佳投放顺序,需试验确定。一般先投无机混凝剂,再投有机混凝剂。但当鑫百利国际客服胶粒粒径在50μm以上时常先加有机混凝剂吸附架桥,再加无机混凝剂压缩扩散层而使胶体脱稳。无机混凝剂石灰与硫酸铝投加顺序,其先后决定pH值的条件,pH影响硫酸铝在水中的形态。又如三氯化铁与石灰的投药顺序对污泥脱水效果有影响,实践证明先投三氯化铁后投石灰时用药剂量少。
