生活垃圾液态混合物的LBP多相分离技术

摘要

Multiphase separation technology in Liquefaction Biochemical Process (LBP) of municipal wastes is studied.Three layers are separated from the liquefied mixture.The top floating layer,composed by synthetic polymers and textile fibers,with sand content≤5％,can be transferred to fuel of high heat value or reutilization.The sediment layer of inorganic particles as sand is landfilled.The middle layer,organic fractions of particle size≤2 mm with sand content≤5％,is then anaerobic digested to produce biogas and organic fertilizer.%研究生活垃圾资源化处理LBP工艺中的多相分离技术,从混合生活废弃物浆液中分离出三类物料:上浮层为合成有机物和纤维碎料,含沙量≤5％,可作为高热值燃料或再生利用;沉淀层分离出的泥沙等无机物不含有机物,可无害填埋;中间层为固形物粒度≤2 mm的生物有机质浆液,含沙量≤5％,具有可生化处理特性,可用作生物厌氧发酵产沼气和制作有机肥的优质原料.
