【摘要】 对污泥处理中的有关理论问题进行了探讨。讨论了污泥、水解和液化以及污泥稳定性等概念。针对污泥处理的目的性 ,首先从污泥稳定化程度评价指标入手 ,对厌氧稳定性试验、污泥碱解试验和污泥液化试验等试验方法进行了深入的对比研究。提出了液化试验这一简单可行的污泥稳定化 (降解程度 )指标的试验方法。更多还原

【Abstract】 In this paper theoretical problems related to sludge treatment have been discussed, the definitions of sludge, hydrolysis and liquefaction as well as sludge stabilization were given. According to the aims of sludge treatment, the index and method to evaluate sludge stabilization were studied at first. The different sludge stabilization evaluation method, such as anaerobic stabilization assay, alkalinity hydrolysis assay and sludge liquefaction test were studied and compared. The relatively simple and feasible method i.e. the liquefaction test for evaluation of sludge stabilization (degradation degree) has been recommended.更多还原
