| 摘 要： | 采用水热技术处理含油污泥，考察了反应温度和反应时间对水热处理后含油污泥性质的影响，分析了含油污泥的减量化效果。实验结果表明：对含水率为70.6%（w）、含油率为32.0%（w）的含油污泥进行水热处理时，与反应时间相比，反应温度对含油污泥的脱水性能影响更大，是影响含油污泥热水解反应的重要因素;含油污泥经水热处理后，脱水性能得到改善，在所有实验条件下减量化率均高于78.8%，其中，在反应温度190 ℃、反应时间30 min的条件下，减量化率达到88.2%。

| Abstract: | Oily sludge was treated by hydrothermal process. The effects of reaction temperature and reaction time on the property of treated sludge were studied and the reduction effect of oily sludge was analyzed. The experimental results indicate that：When the oily sludge with 70.6%(w) of moisture content and 32.0%(w) of oil content is treated by hydrothermal process，reaction temperature has a greater effect on the dewatering property of oily sludge than reaction time，and it is an important factor affecting thermal hydrolysis of oily sludge;The dewatering property of oily sludge is improved after hydrothermal treatment with more than 78.8% of reduction rate under all experimental conditions，and the reduction rate is 88.2% when the reaction temperature is 190 ℃ and the reaction time is 30 min. |
