摘　　要：焦化废水的成分十分复杂,除含苯系物外,还含有多环芳香烃和杂环类有机物。研究表明,选择适合的微生物,并采用相应的生物反应器及处理工艺,可有效去除焦化废水中的COD和其他有毒化合物。文章从降解焦化废水的微生物种类、生物降解原理、降解方法、生物反应器及工艺流程等方面,阐述了焦化废水微生物降解的最新研究进展。指出了焦化废水微生物处理需进一步解决的问题。The coke plant wastewater contains very complexand toxic compounds that are harmful for microor-ganisms and human, including benzenes, heterocycliccompounds as well as polycyclic aromatic hydrocar-bons. Some species of microorganisms have the abilityto decompose these compounds. COD and toxic com-pounds in the coke plant wastewater can be treatedeffectively by using the domesticated strains, corre-sponding bioreactors, and treatment processes. Thepresent paper introduced the most newly advances onwastewater biodegradation of coke plant by microor-ganisms, including microbial species, principle, degra-dation methods, bioreactors, and the treatment pro-cesses, also pointed out the remaining problems inmicrobial degradation of coke plant wastewater whichneed to be solved in the future.
