通过对含油污泥进行铝溶出实验和制备聚合氯化铝（PAC ）及其应用研究，实现含油污泥的资源化处理及再生利用。结果表明，在70℃下，采用4 mol／L的硫酸30 mL ，铝溶出率达到最大值44．04％，加入少量乙醇，其溶出率更大，但实际应用中会消耗很多能量，应予以考虑。对含油污泥进行再生利用的方法研究，采用盐酸处理含油污泥进行PAC制备并用其处理模拟染料废水，结果表明，在盐基度80％条件下，对于低浓度模拟染料废水，PAC最佳投加量为2．5 mL／L；对高浓度模拟染料废水，PAC最佳投加量为15 mL／L。

By studying aluminum extraction from oily sludge ,preparation and application of polyaluminium chloride (PAC ) , it is aimed to realize the resource treatment and recycled utilization of oily sludge .The result shows that aluminum extraction rate can reach the maximum (44 .04% ) with 30 mL of sulpuric acid 4 mol/L at the temperature of 70 ℃ and the extraction rate will be higher when less ethanol is mixed .However ,the large energy consumption should also be taken into considera-tion .Furthermore ,the recycling and reutilization of oily sludge are also studied .Oily sludge is acidized by hydrochloric acid to produce PAC ,which is used to purify the simulated dye wastewater .The results show that the best dosage is 2 .5 mL/L for the low strength wastewater and 15 mL/L for the high strength wastewater with the basicity of 80% .
