Abstract
Description
污泥处置方法 | 基本特征 | 优缺点 |
本发明处置方法 | 含水分75%的新鲜污泥直接进入烘干搅拌机,烘干成粒后入悬浮炉悬浮煅烧,废渣进入水泥熟料烧成***。 | 1.污泥烘干后热值高,利于燃烧;2.悬浮炉结构简单,操作简便,无需排渣处理;3.流化床可缓冲污泥喂料的不均衡性,并对污泥压床有一定的适应性; |
4.燃料在高温的纯空气中点燃,有利于燃料的着火燃烧。 | ||
填埋法 | 将污泥进行填埋处理。 | 1.污泥填埋需占用土地,投资高;2.存在二次污染的隐患。 |
堆肥法 | 将污泥堆积并作为农业或花草用肥料需加入膨化剂 | 1.污泥作为肥料可节省费用.2.堆肥处置的污泥在经过自然风干和生物分解后利用,其氮、磷、钾含量明显低于有机肥;3.堆肥易使污泥中的重金属富集,对农作物及花草产生不良影响4.膨化剂回收不彻底,5环境污染(气体外逸) |
循环流化床焚烧法 | 污泥在循环流化床中焚烧,污泥焚烧具有鼓泡流化床的基本特征。 | 1.污泥焚烧彻底;2.需经常进行排渣处理,***复杂。 |
