摘要/Abstract

摘要： 为研究含油废水处理产生的剩余污泥和气浮污泥的厌氧消化性能，试验采取序批式厌氧消化两种含油污泥的方法，对含油污泥的组成变化及产气性能进行测定，并将其结果与市政剩余污泥进行对比。试验结果显示，经过35天的厌氧消化，含油剩余污泥和含油气浮污泥的可挥发固体（VS）降解率分别为4.98%和3.74%，TCOD降解率分别为10%和3.4%，产气量分别为0.97 L/gVS和0.56 L/gVS。经过和市政剩余污泥对比后表明，含油气浮污泥厌氧消化性能差，不宜进行厌氧消化处理；含油剩余污泥厌氧消化性能相对强于含油气浮污泥，但弱于市政剩余污泥。

Abstract: In order to explore the anaerobic digestion performance of the oily sludge，anaerobic batch mode was taken for the oily excess sludge and oily scum sludge produced in a wastewater treatment plant. During anaerobic digestion，composition changes of oily sludge and the volume of biogas produced were measured and then compared with the results of municipal excess sludge. The results showed that after 35 days anaerobic digestion，for oily excess sludge and oily scum sludge the VS removal efficiencies were 4.98% and 3.74%，the TCOD removal efficiencies were 10% and 3.4%，and the volume of biogas produced were 0.97 L/(gVS) and 0.56 L/(gVS). It demonstrated that anaerobic degradability of oily scum sludge was not desirable. Even the results of anaerobic degradability of oily excess sludge were better，it may not be feasible to use anaerobic digestion in oily sludge treatment.
