污泥的衛生填埋污泥的衛生填埋 Sanitary landfill of sludge 這種處置方法簡單、易行、成本低,污泥又不需要高度脫水,適應性強。但是污泥填埋也存在一些問題,尤指填埋滲濾液和氣體的形成。滲濾液是一種被嚴重污染的液體,如果填埋場選址或運行不當會污染地下水環境。填埋場產生的氣體主要是甲烷,若不采取適當措施會引起爆炸和燃燒。 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. 污泥填埋場 Sludge landfill 2、污泥制肥 2. Sludge fertilizer 污泥制肥直接利用因投資少、能耗低、運行費用低、有機部分可轉化成土壤改良劑成分等優點,被認為是最有發展潛力的一種處置方式,將脫水后含水率78%-85%的污泥,經烘干后含水率達30%-40%。經過污泥制肥設備(污泥制肥工藝方法),使污泥中有機物轉化成富含植物營養物的腐殖質,反應的最終代謝物為CO2,、HO2和熱量,大量熱量使物料堆持續高溫60,降低含水率,有效去除病原體,寄生蟲卵和雜草種子,使泥達到減容化、穩定化、無害化、資源化的目的。 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. 上一篇污泥處理就是對污泥進行濃縮下一篇濕污泥干化后再直接焚燒 |
