污泥的卫生填埋 Sanitary landfill of sludge 这种处置方法简单、易行、成本低,污泥又不需要高度脱水,适应性强。但是污泥填埋也存在一些问题,尤指填埋渗滤液和气体的形成。渗滤液是一种被严重污染的液体,如果填埋场选址或运行不当会污染地下水环境。填埋场产生的气体主要是甲烷,若不采取适当措施会引起爆炸和燃烧。 This treatment method is simple, easy, low cost, sludge does not need high dehydration, and has strong adaptability. However, there are also some problems in sludge landfill, especially the
污泥的焚烧 Incineration of sludge 湿污泥干化后再直接焚烧应用得较为普遍,没有经过干化的污泥直接进行焚烧不仅十分困难,而且在能耗上也是极不经济的。 Direct incineration of wet sludge after drying is widely used. Direct incineration of sludge without drying is not only very difficult, but also very uneconomic in energy consumption. 污泥焚烧处理 Sludge incineration treatment 以焚烧为核心的污泥处理方法是最彻底的污泥处理方法,它能使有机物全部碳化,杀死病原体,可最大限度地减少污泥体
