摘　　要：通过对当前含油污泥脱水技术进行调研,归纳出当前主要脱水技术为化学法脱水、机械法脱水、微波法脱水和超声法脱水,总结了各种方法的脱水原理、影响因素和国内外研究现状。目前未有一项脱水技术能够对所有的含油污泥进行高效率的脱水,均具有局限性,因此今后开发新的脱水药剂、脱水方法或者将已开发的技术进行联合脱水是进一步研究的热点。建议合成效率高、有经济效益、绿色和普适性的表面活性剂,并结合工业应用的微波以及超声设备,开展相应工业化规模的实验。The current oily sludge dewatering technology was investigated.It is found that the current main dewatering technologies are chemical dewatering,mechanical dewatering,microwave dewatering and ultrasonic dewatering,respectively.The influencing factors and research status of the current major dewatering technology of oily sludge were summarized.No dehydration technique can efficiently dehydrate all oily sludge at present.Therefore,developing new dehydration chemicals and dehydration methods,or combining the developed technology are widely developed.It is recommended to synthesize high-efficiency,economical,green and universal surfactants,and combine microwave and ultrasonic equipment to carry out corresponding industrial-scale experiments.
