A novel application of micro-aerobic hydrolysis and acidification on the treatment of refractory Chinese traditional medicine wastewater

摘要

The performance of micro-aerobic hydrolysis and acidification on the treatment of refractory Chinese traditional medicine wastewater was studied. The results indicate that it is efficient pre-treatment for reducing toxicity, improving biodegradability and removing organic pollutants from dyestuff wastewater. The effluent quality was relatively stable with the fluctuant influent while the removal efficiencies of COD and SS were 28% and 81% respectively, and more importantly, the increment of BOD_5/COD ratio was about 0.18.
