摘要
采用Fenton试剂氧化-水解酸化-Biofor（一段式生物过滤氧化反应器）工艺处理硝基苯胺类农药废水。结果表明：Fenton试剂氧化CODCr去除率为73．8％，色度去除率为88．7％；水解酸化-Biofor工艺处理CODCr去除率在20％～60％，色度去除率为63．9％，在总进水CODcr≤19870mg/L、色度≤20000倍时，采用Fenton试剂氧化-水解酸化-Biofor工艺，加入适当的冷却水稀释盐分，处理后出水CODCr〈100mg／L、色度〈50倍。
Fenton reagent oxidation-hydrolytic acidification-Biofor process used for treating nitroaniline pesticide wastewater is described. The results show that the removal rates of CODCr and chroma are 73.8% and 88.7% respectively by Fenton reagent oxidation; and the removal rates of CODCr and chroma are 20%-60% and 63.9% respectively by hydrolytic acidification-Biofor process. When the total influent CODCr and chroma are ≤ 19 870 mg/L and ≤ 20 000 times, respectively. Fenton reagent oxidation-hydrolytic acidification-Biofor process is used, adding adequate cooling water to dilute salinity. After the treatment, the CODCr of effluent is less than 100 mg/L and the chroma is less than 50 times.
