摘　　要：煤气化是煤化工的龙头和基础,但其所产生的废水中污染物含量高且水质复杂。基于国内外各种煤气化技术和工艺特点,在分析煤化工废水的水质及来源的基础上,重点探讨了固定床煤气化废水在预处理、生化处理和深度处理等方面的研究进展,指出煤气化废水的处理应综合考虑废水水质、环境承载能力等实际因素,并需合理组合现有废水处理技术。Coal gasification is the leader and foundation of coal chemical industry,however,its wastewater contains high content of pollutants with complexed water quality.Based on various coal gasification technologies and process features at home and abroad,the quality and sources of coal chemical wastewater were analyzed,with key focus on the research progress of fixed-bed coal gasification wastewater treatment technologies in terms of pretreatment,biochemical treatment,and advanced treatment.It was pointed out that the coal gasification wastewater treatment should comprehensively consider practical factors such as wastewater quality and environmental capacity,and should also reasonably combine existing treatment technologies.
