Treatment of anthraquinone dye wastewater by hydrolytic acidification-aerobic process.
Experiment on microbial degradation with two kinds of biological process, hydrolytic acidification-aerobic process and aerobic process was conducted to treat the anthraquinone dye wastewater with COD(Cr) concentration of 400 mg/L and chroma 800. The experimental result demonstrated that the hydrolytic-aerobic process could raise the biodegradability of anthraquinone dye wastewater effectively. The effluent COD(Cr) can reach 120-170 mg/L and chroma 150 which is superior to that from simple aerobic process.
