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 formation of landfill leachate and gas. Leachate is a kind of seriously polluted liquid. If the landfill site is selected or operated improperly, it will pollute the groundwater environment. The gas produced by landfill site is mainly methane, which will cause explosion and combustion if appropriate measures are not taken.

　　2、污泥制肥

　　2. Sludge fertilizer

　　污泥制肥直接利用因投资少、能耗低、运行费用低、有机部分可转化成土壤改良剂成分等优点，被认为是最有发展潜力的一种处置方式，将脱水后含水率78%-85%的污泥，经烘干后含水率达30%-40%。经过污泥制肥设备(污泥制肥工艺方法)，使污泥中有机物转化成富含植物营养物的腐殖质，反应的最终代谢物为CO2,、HO2和热量，大量热量使物料堆持续高温60，降低含水率，有效去除病原体，寄生虫卵和杂草种子，使泥达到减容化、稳定化、无害化、资源化的目的。

　　Due to the advantages of low investment, low energy consumption, low operation cost and the organic part can be transformed into soil conditioner, the direct utilization of sludge fertilizer is considered to be the most potential disposal method. The sludge with water content of 78% - 85% after dehydration and 30% - 40% after drying. Through the sludge fertilizer making equipment (sludge fertilizer making process method), the organic matter in the sludge is transformed into humus rich in plant nutrients. The final metabolites of the reaction are CO2, HO2 and heat. A large amount of heat keeps the material pile at a high temperature for 60, reduces the moisture content, effectively removes pathogens, parasitic eggs and weed seeds, and makes the sludge volume reduced, stabilized and harmless The purpose of resource utilization.
