厌氧水解-好氧处理蒽醌废水试验研究

Experimental Study on Treatment of Anthraquinone Dye Wastewater by Hydrolytic-Anaerobic Aerobic Process

采用厌氧水解-好氧和单独好氧处理两种生化方法对蒽醌染整废水进行了平行对照试验。结果表明,厌氧水解-好氧处理方法可有效地提高该废水的可生化程度。当进水COD_(Cr)浓度为400mg/L、色度为800倍时,厌氧水解-好氧处理后出水COD_(Cr)可达120-170mg/L,COD_(Cr)去除率在63％以上,色度降低至150倍,明显优于单一好氧处理的出水水质。

Experiment on microbial degradation with two kinds of biological process, hydrolytic acidification-anaerobic process and aerobic process has been conducted to treat anthraquinone dye wastewater with CODcr concentration of 400mg/L and chroma 800. The experimental result demonstrated that the hydro-lytic-anaerobic-aerobic process could raise the biode-gradability of anthraquinone dye wastewater effectively. The effluent CODcr could reach 120-170mg/L and chroma 150 which is superior to that from simple aerobic process.
