复合型无机凝聚剂对剩余污泥减容处理技术

The Technology of Excess Sludge Reduction with Complex Inorganic Coagulant

利用复合型无机凝聚剂替代PAM对剩余污泥的处理技术,有利于污泥与水的高效分离,经凝聚减容沉淀后的浓缩污泥具有很好的压缩性和脱水性,产生的泥饼含水率大幅度降低至60%以下,便于后期无害化处置与资源化再利用。

The sludge reduction technology by using complex inorganic coagulant instead of PAM can separate sludge from water efficiently.The concentrated sludge after coagulation-precipitation has excellent compressibility and dewatering property.And the water content of the sludge cake can be reduced to lower than 60%,which is convenient for later harmless disposal and recycle.
