摘要:

苯酚厌氧降解微生物可分为产甲烷聚生体细菌、硫酸盐还原细菌、反硝化细菌及金属还原细菌。苯酚在常温厌氧条件下以苯甲酸为中间产物进行降解,但是苯酚向苯甲酸的转化过程以及高温条件下苯酚降解机理仍处于争论阶段。苯酚羧化是反应的限速环节。针对高浓度苯酚对微生物活性的抑制问题,目前采用的主要方法有改变温度、物理吸附、回流稀释以及投加共代谢基质。最后提出了厌氧降解含酚废水的发展前景和研究方向。

Abstract:

An aerobic degradation of phenol canbe classifiedas:methan ogenic fermentation by the consortia ofbacteria, sulfate-reducing bacteria, denitrifying bacteria and metal-reducing bacteria. Theevidence for anaerobicmetabolism of phenol viabenzoateat ambient temperature is presented. However, theconversion mechanism fromphenol tobenzoate at ambient temperature and phenol degradation at thermophilic condition are still underdiscussion.The initial acidogenesis is the rate-limitingstep.The high concentration phenol can be effectivelytreated with different temperature, adsorption, recirculation of the treated effluent and supplementing with cosubstrates. The prospects and direction of an aerobic wastewater treatment containing phenol sisalsosuggested. Itis competent for basicguidancein this field.

Key words: phenol, anaerobe, benzoate
