摘要：
针对腈纶废水有机成分复杂、B/C低和生物毒性大的特点，采用微电解-Fenton-BAF组合工艺进行腈纶废水生化出水的深度处理试验，并优化工艺。结果表明：在优化试验条件下，最终出水色度可维持在30~50倍，出水COD维持在50~80 mg/L；同时，充分利用组合工艺特点，无需反复调节废水pH和投加铁粉，节省工艺成本。

Abstract:
Aiming at the characteristics of acrylic fiber wastewater, such as complex organic components, low B/C and high biological toxicity, the combined process, microelectrolysis-Fenton-biological aerated filter, has been used for the advanced treatment and technological optimization of its secondary effluent.The results show that, under the optimal conditions, the final effluent chroma is maintained at 30-50 times, and COD is maintained at 50-80 mg/L.Moreover, by making full use of the characteristics of the combined process, it is not necessary to regulate the wastewater pH and add iron powder.As a result, the process cost can be saved to a certain extent.
