摘要
随着我国石油产业化发展,含油污泥产量不断增加,面对巨大的环保压力,油田提出提质增效,含油污泥的减量化、无害化和资源化处置势在必行。根据国内外含油污泥处理技术和工艺特点,建议含油污泥从源头进行减量以减少含油污泥的产生,针对不同的含油污泥类型筛选不同的技术工艺,尽量地回收原油,低含油量的污泥采用电化学生物耦合等技术,对于含油较高的稠油类型污泥采用“热洗+干化+热解技术”;尽快地出台国家级的含油污泥处理相关标准,对于以满足排放达标的含油污泥给出明确的处置和资源化方法,给出执行标准。为了协调油田发展和环境保护之间的平衡,积极寻求绿色、节能、高效的含油污泥处理技术是今后含油污泥处理的主要发展方向。
With the development of China's petroleum industrialization,the output of oily sludge is increasing.Facing the enormous pressure of environmental protection,the oilfield proposes to improve quality and increase efficiency.The reduction,harmlessness and resource disposal of oily sludge are imperative.According to the characteristics of oily sludge treatment technology and process at home and abroad,it is suggested to reduce the amount of oily sludge from the source to reduce the production of oily sludge.According to different types of oily sludge,different technology processes should be selected to recover crude oil as much as possible.The sludge with low oil content adopts electrochemical biocoupling technology,and for the heavy oil type sludge with high oil content,"hot washing+drying+pyrolysis technology"is adopted.The national oil sludge treatment standards should be issued quickly,and the disposal and resource recovery methods and implementation standards should be provided for the oil sludge to meet the discharge standards.In order to coordinate the balance between oilfield development and environmental protection,it is the main development direction of oil sludge treatment in the future to actively seek green,energy-saving,and efficient oil sludge treatment technology.
