摘要
对污泥稳定的定义及目标进行了介绍,并对评价厌氧污泥稳定度的参数指标进行了综述,推荐的几个测试是:挥发性固体减少率、不稳定物质减少测试、腐殖质含量、植物毒性测试,指出应从两个方面来考虑对参数进行选择,需要掌握稳定化过程的信息量和最终资源化利用的方式。
The definition and objectives of the sludge stabilization are introduced in this paper, and the parameters and indexes for evaluating the anaerobic sludge stability are also summarized. Tests on reduction percent of volatile solids, reduction of unstable substances, content of humic substances and phytotoxicity are recommended. Two aspects should be considered in choosing the parameters. Information quantity of the stabilization process and the manner of ultimate resource use need to be mastered.
