摘要
本文考察了高温厌氧消化处理炼油厂浮选渣的过滤脱水效果，得出在污泥停留时间为10天的条件下，厌氧过程能较好地进行；高温消化后的污泥过滤脱水性能有较大的改善；过滤后的滤饼含水率明显降低，由新鲜浮渣的91％可降到57％。
The filtering and dewaering effect of flotation residue treated with anaerobic digestion of high temperature is studied in this paper,These results are obtained that anaerobic digestion can be conducted very well on the condition of 10d retention period of sludge, the filtering and dewaering property of sludge treated with anaerobic digestion of high temperaure is improved distinctly, the waer proportion of filtered cake is lowered to 57%from 91% of fresh flotation residue.
