Abstract: | Coke plant effluents with high contents of organic compounds are mainly treated by biological aerobic fermentation after physical pre-treatment.In this study,a brown coal condensate wastewater from a low temperature coking process was fermented under methanogenic conditions in discontinuous experiments.By this fermentation,acetate,propionate,and the main polyphenolic compounds(catechol,resorcinol and hydroquinone) were degraded to a level below the detection limit.The COD was reduced by 72% with a residual ... |
