- 摘要:
- 某农药中间体生产企业废水甲苯、二甲苯、挥发酚、苯胺类苯系有机污染物浓度较高,采用铁碳微电解/Fenton氧化/混凝沉淀/UASB反应器/AO组合工艺进行处理。运行结果表明,Fe2+利用率高,稳定运行阶段出水甲苯<0.1 mg/L、二甲苯<0.4 mg/L、苯胺类<0.5 mg/L、挥发酚<0.5 mg/L,去除率分别大于99.9%、96.0%、79.0%、99.8%,出水水质稳定达到化工园区污水厂接管标准。该组合工艺能有效适应农药中间体生产废水水质不稳定的特点,其中铁碳微电解反应器采用一体式复合填料流化床工艺,有效缓解了铁碳填料易板结问题。
- Abstract:
- A combined process of Fe/C microelectrolysis, Fenton oxidation, coagulation, UASB reactor, and AO is adopted to treat high concentration of monoaromatic hydrocarbons such as toluene, xylene, volatile phenol, and aniline in the production of pesticide intermediate. The effluent toluene, xylene, aniline and volatile phenol were less than 0.1 mg/L, 0.4 mg/L, 0.5 mg/L, and 0.5 mg/L respectively during the stable operation stage, and the removal rates of these pollutants were greater than 99.9%, 96.0%, 79.0%, and 99.8%, respectively, which met the takeover standard of the wastewater treatment plant in the local chemical park. Additionally, this oxidation/biochemical process can be effectively adapted to the characteristics of unstable quality of pesticide intermediate wastewater. The Fe/C microelectrolysis reactor adopts an integrated composite filler fluidized bed process, which effectively alleviates the problems of iron and carbon filler packing.
