摘　　要：随着城市化的持续推进和科学技术的发展,基于社会发展对煤炭及其附属产物的需求量不断增加,在促进煤化工行业高速发展下,需要关注煤液化工艺中出现的三废(废水、废气、废渣)排放问题。结合当前煤化工行业生产需要落实的可持续、绿色生产理念,如何做好三废排放问题的处理,也成为很多煤化工企业需要考虑的问题。为此,先后对废水、废气、废渣的排放问题及处理技术进行分析,最后对三废排放问题的治理策略进行讨论,以期望可以降低煤液化过程对环境的污染,促进煤化工行业实现可持续发展。With the continuous advancement of urbanization and the development of science and technology,based on the increasing demand of social development for coal and its ancillary products,under the promotion of the rapid development of the coal chemical industry,it is necessary to pay attention to the emission of three wastes(wastewater,waste gas,waste residue)in the coal liquefaction process.Combining the sustainable and green production concepts that need to be implemented in the current coal chemical industry,how to effectively address the issue of three waste emissions has also become a problem that many coal chemical enterprises need to consider.For this reason,the discharge problems and treatment technologies of waste water,waste gas and waste residue were analyzed successively,and finally the treatment strategies of the three wastes discharge were discussed in order to reduce the environmental pollution caused by the coal liquefaction process and promote the sustainable development of the coal chemical industry.
