摘要:
针对难降解制膜工业废水，采用铁碳微电解/好氧颗粒污泥耦合工艺进行处理，铁碳微电解为连续流，好氧颗粒污泥为序批式反应器（SBR）。耦合工艺系统成功培育出具有优异沉降性能的好氧颗粒污泥，120 d时SVI30在30 mL/g左右、平均粒径为316 μm；出水COD、NH4+-N和TN浓度分别为130.1、6.6、23.7 mg/L，处理效果优于对照组。铁碳微电解预处理不但能提高废水的B/C值，而且能促进生化处理段颗粒污泥的形成，有利于难降解工业废水的处理。
Abstract:
Refractory membrane industrial wastewater was treated by a coupling treatment process of FeC microelectrolysis/aerobic granular sludge. The FeC microelectrolysis was operated in continuous flow mode, and the aerobic granular sludge was cultivated in a sequencing batch reactor (SBR). Aerobic granular sludge with excellent sedimentation performance was successfully cultivated in the coupling system. The SVI30 was about 30 mL/g and the average particle size was 316 μm at 120 days. The concentrations of COD, TN and NH4+-N in the effluent were 130.1 mg/L, 23.7 mg/L and 6.6 mg/L respectively, and the treatment efficiency was better than that of the control group. The Fe-C microelectrolysis pretreatment could not only improve the B/C ratio of sewage, but also promote the formation of granular sludge in the biochemical treatment section, which was beneficial to the treatment of refractory industrial wastewater.
