水解—好氧工艺处理香兰素废水试验研究

Experimental study on the treatment of perfume wastewater by hydrolysis-aerobic process

采用水解—好氧工艺对香兰素废水进行处理,在进水COD在≤1000mg/L,BOD5≤300mg/L,色度≤80倍,水解停留时间≥4h,好氧曝气停留时间≥25h,常温的条件下,出水COD≤100mg/L,色度降为10倍,COD去除率≥90%。

Perfume wastewater has been treated by hydrolysis-aerobic process. The COD of influent water is ≤ 1 000 mg/L, BOD5 ≤ 300 mg/L, ehroma ≤ 80, hydrolysis HRT ≥4 h, aerobic HRT ≥25 h. The results show that at normal temperature, the effluent COD ≤ 100 mg/L, chroma 10 times, the COD removal rate ≥ 90%.
