摘要
针对酸性玫瑰红印染废水的高色度、难以生物降解的特点,采用O3和Fenton试剂进行氧化处理,通过实验确定了最佳运行参数。研究表明:在最佳运行参数下,O3处理废水的色度去除率大于99%,CODcr的去除率30%; Fenton试剂处理色度去除率大于99%,CODcr去除率47%。两种化学氧化处理都可以大大提高模拟废水的可生化性。
Acid rose red dye wastewater is deeply colored and hardly to be bio-degradable. Chemical oxidation by Fenton and O3 was applied. The optimum operation parameters of each oxidizing agent were determined through experiments, the results showed that, by using O3 the color of wastewater could be reduced by 99% and CODCr by 30%. However, the color of wastewater could also be reduced by 99% and CODCr by 47% if using Fenton reagent. The biodegradability of the wastewater was greatly improved by both of them.
