Treatment of anthraquinone dye wastewater by hydrolytic acidification-aerobic process

Experiment on microbial degradation with two kinds of biological process, hydrolytic adification aerobic process and aerobic process was conducted to treat the anthraquinone dye wastewater with CODCr 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 CODCr, can reach 120-170 mg/L and chroma 150 which is superior to that from simple aerobic process.
