【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≤19 870 mg/L、色度≤20 000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<100 mg/L、色度<50倍。更多还原

【Abstract】 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.更多还原
