摘要
含油污泥是制约油田生产节能环保的关键问题之一。含油污泥因其来源广泛,成分复杂,相应的处理技术和设备也呈现多元化趋势。本文针对目前含油污泥的处理现状,对当前国内外含油污泥处理的常规方法进行了分类并作对比分析,总结了常规处理方法的应用范围及其优缺点。着重介绍了几种新型处理技术,包括与超声清洗联用、超临界水氧化技术、回注调剖等,对各种方法的原理、特点及适用情况进行了描述。由于含油泥砂来源广泛、成分复杂,同时处理技术种类繁多,且都存在各自的应用弊端和适用范围。综合处理效果、环保及节能的因素,目前尚没有任何一种技术可以作为处理所有类型含油泥砂的理想方法,有待继续研究。最后,文章总结了含油污泥处理过程中遇到的问题,并简介联用技术的应用前景。
Oily sludge treatment is one of the important problems of environmental protection and sustainable development.There are many different kinds of oily sludge and these nature are complex,at the same time the corresponding technology and equipment also showed a diversified trend.According to the present situation of oily sludge treatment,on the conventional method of oily sludge treatment at home and abroad are classified and comparative analysis,summarizes the application range of conventional processing methods and their advantages and disadvantages.Some kinds of new technology are introduced,including ultrasonic cleaning,supercritical water oxidation technology,reinjection profile control and so on.The principle,characteristics and application condition of various methods are described.Due to the complexity of oil sludge and source widely,its composition,at the same time there are many different kinds of processing technology which has their own disadvantages and applicable scope.Synthesizes these factors,such as effect of treatment,environmental protection and energy saving,there is not any kind of technology can be used as an ideal method of processing all types of clay sand,and have to continue to study.Finally,the article summarizes the problems in the process of oily sludge treatment,and brief to introduce application prospect for integrated utilization.
