Study on anaerobic biodegradation of resin wastewater after TiO2 photocatalytic pretreatment
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 TiO2 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 TiO2 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 TiO2 photocatalytic pretreated wastewater and untreated raw water was increased by 10%-15%.
