如何使用聚合氯化铝处理屠宰污水

2020-04-13 安禄环保 5

屠宰废水聚合氯化铝PAC的选型,屠宰废水一般呈红褐色,有难闻的腥臭味,其间含有很多的血污,油脂质,毛,肉屑,骨屑,内脏杂物,未消化的食物,粪便等污物,固体悬浮物含量高。屠宰废水有机物含量高,可生化性好,但其间高浓度有机质不易降解,处理难度较大。屠宰废水中的养分物主要是氮,磷,其间氮主要以有机物或铵盐方式存在,而磷主要以磷酸盐的方式存在。
混凝处理常用的混凝剂有铝盐!铁盐等,其间聚合硫酸铁混凝处理屠宰废水作用较好,为削减铝盐的运用量,也可用聚合氯化铝和聚乙烯铵混合作为混凝剂在聚合硫酸铁的组成中,加入恣意份额的铝盐和必定份额的硅酸盐,以及少数的聚丙烯酰胺生成一种新混凝剂。
