高盐含酚废水生物处理技术的研究进展及应用前景

RESEARCH PROGRESS OF BIOLOGICAL TREATMENT TECHNOLOGIES FOR PHENOLIC WASTEWATER WITH HIGH SALINITY AND THEIR APPLICATION PROSPECTS

高盐含酚废水治理是污水处理领域亟待解决的一个难题。目前,以微生物为核心的生物处理高盐含酚废水技术备受关注。迄今为止,耐盐降酚微生物的筛选菌源仅限于基于常规分离培养方法所能获得的仅占0.01%~10%的微生物菌群,大量的潜在功能菌群因处于有活性但非可培养(viable but non-culturable,VBNC)状态而未被研究。在阐述耐盐降酚微生物研究现状的基础上,结合课题组的研究结果,提出利用复苏促进因子(resuscitation promoting factor,Rpf)探索具有潜在耐盐降酚功能的微生物,为复苏培养高效耐盐降酚菌提供新思路,并为生物强化处理高浓度有机工业废水提供有效的方法途径。

Phenolic wastewater with high salinity remains as a bottleneck in the wastewater treatment,and biological process is still of major interest to researchers and operators. However,until now,only a few（ 0. 01% ~ 10%） of salt-tolerant phenoldegrading microorganisms are isolated in pure culture by conventional isolation and culture methods,and the majority of potential functional microorganisms are in viable but non-culturable（ VBNC） state. As a result,these potential functional microorganisms have not been well investigated. In this review,we provided an overview of research progress in salt-tolerant phenol-degrading microorganisms. Incorporated our previous studies in this review,it was proposed that resuscitation promoting factor（ Rpf） could be used to explore the potential microbes of phenol-degradation under high salinity conditions. It provided new insight into the resuscitation and cultivation of highly effective salt-tolerant phenol-degrading microorganisms. Meanwhile,it provided an effective way for enhancing the treatment of high concentraction organic industrial wastewater.
