鲁奇碎煤加压气化高含盐高COD废水处理技术及改造建议

Lurgi conny pressurized gasification waste water with high-salinity and high COD treatment technology and modification application

以国内某大型鲁奇碎煤加压气化技术制合成天然气的示范项目为例,介绍了项目配套的重要环保设施——高含盐高COD废水处理工艺路线的应用及其运行状况,分析了浓盐废水处理单元中存在的问题及改造思路,对废水零排放技术应用提出建议。

Taking a demonstration project of a large domestic Lurgi coal cr ushing and gasif ication technology to synthesize natural gas as example,this paper introduces the application and operating conditions of the important environmental protection facilities,that is t reat ment process route of waste water with high salt-containing and high COD.The problems existing in the concentrated brine waste water treatment unit are analyzed,and suggestions are put forward for the application of zero emission technology of waste water.
