摘　　要：为研究高浓度树脂废水的厌氧生物处理技术,采用厌氧生物法对TiO_(2)光催化预处理后树脂废水进行处理,并考察了葡萄糖共基质对废水中物质降解的影响。结果表明:驯化厌氧污泥对TiO_(2)光催化预处理后废水处理效果较好,COD最终去除率可以达到80%以上,与未预处理废水相比,COD去除率提高20~30个百分点;投加葡萄糖作为共基质,提高了微生物降解难降解物质的效率,TiO_(2)光催化预处理废水和未预处理原水中挥发酚去除率均提高10~15个百分点。To study the anaerobic biological treatment technology of high concentration resin wastewater,the anaerobic biological method was used to treat the resin wastewater pretreated with TiO_(2) photocatalysis,and the effect of glucose co-substrate on the degradation of substances in the wastewater was investigated.The results showed that the domesticated anaerobic sludge had a good effect on the wastewater treatment after TiO_(2) photocatalytic pretreatment.Compared with the non-pretreated wastewater,the final removal rate of COD could reach more than 80%,increased by 20%-30%.The addition of glucose as a co-substrate improved the efficiency of microbial degradation of refractory substances,and the removal rate of volatile phenol in TiO_(2) photocatalytic pretreated wastewater and untreated raw water was increased by 10%-15%.
