摘要
介绍了近年来煤气化废水除油、沉淀、萃取脱酚预处理方法,主要有A/O和A2/O工艺、SBR、Bio Dopp及EGSB等生物处理方法,以及臭氧氧化、BAF及Fenton试剂氧化深度处理方法;阐明了强化预处理、生物处理以及深度处理技术的组合将是煤气化废水处理的发展趋势。
This article introduces preprocessing method of unoil,sediment,extraction and dephenolization to coal gasification wastewater in recent years,biotreatment method of technology of A/O and A^2/O,SBR、BioDopp and EGSB,and advanced treatment method of ozonation,BAF and oxidation of Fenton reagent.At last,it illuminates the growing trend of dealing coal gasification wastewater is the combination of technologies of intensifying preprocessing,biotreatment and advanced treatment.
