煤制气废水处理技术研究进展综述

Progress in Treatment Technologies for Coal Gasification Wastewater

基于中国能源结构特点,新型煤化工产业近年来得到大力推进,尤其煤制气项目发展迅速,而煤化工废水处理及综合利用成为限制其发展的瓶颈因素之一。文中介绍了煤制气废水来源、特点、处理难度,依照煤制气废水的常规处理流程,从预处理、生化处理、深度处理三个方面详细介绍国内外煤制气废水处理应用实例及技术研究现状,指出废水处理关键问题,为解决煤制气产业废水治理问题提供参考。

Based on the structural characteristics of Chinese energy, new coal chemical industry is being promoted in recent years. The coal gasification project developed rapidly. However, wastewater treatment and comprehensive utilization of coal gasification project are becoming one of the factors restricting the development. In this paper, the characteristics and treatment difficulties of coal gasification wastewater are introduced, according to conventional coal gasification wastewater treatment process, detailing the domestic coal gasification wastewater treatment technology research and application examples from the pretreatment, biochemical treatment and advanced treatment. It pointed out the key issues of wastewater treatment and provide reference idea for coal gasification project to solve wastewater treatment problems.
