摘要:

污泥破解是指通过一定的方法,破坏污泥的絮体结构、细胞壁,溶出胞内物质。污泥破解的结果是水相中有机物含量提高。主要介绍了污泥破解的非生物方法,如物理破解法,包括高压喷射、珠磨、超声波等机械方法与加热法;化学破解法,包括碱解法与氧化法等;另外,还有超声波加碱、热化学等组合方法,并介绍了这些方法的原理与主要研究结果。

关键词: 污泥破解, 物理法, 化学法, 组合法

Abstract:

Sludge disruption is a new technology,which aims at destroying the floc structure of the sludge and cell wall.By doing this,the content inside the cell solubilises and the amounts of degradable organics in the water is increased.A comprehensive review on the research of the technology of the sludge disruption has been given in this paper.The article focuses on introducing the non-biological method.

Key words: sludge disruption, physical method, chemical method, combined method
