摘要:- 浙江某工业废水处理厂升级改造，采用AAO—MBBR复合生物膜工艺，在未新增建设用地和扩建池容的基础上，日处理量由3×104 m3/d提高至6×104 m3/d。改造后实际运行出水COD、TP、NH3-N和TN浓度分别为（37.7±6.61）、（0.09±0.03）、（0.25±0.14）和（5.87±1.54） mg/L，出水水质稳定达到一级A标准。实际监测表明，在好氧MBBR区存在TN去除现象，约占TN总去除量的10.36%。系统内的优势硝化菌属为硝化螺旋菌属Nitrospira，其在悬浮载体生物膜和活性污泥中的相对丰度分别为8.98%和0.92%，悬浮载体的投加使硝化细菌得到有效富集；反硝化菌在生物膜中的占比为7.94%，为悬浮载体同步硝化反硝化（SND）效果的发生提供了微观保证，提高了TN去除率。
Abstract:- An industrial wastewater treatment plant in Zhejiang was upgraded by a combined process consisting of anaerobic/anoxic/oxic activated sludge process and moving bed biofilm reactor (AAO-MBBR). Without changing the footprint and increasing the reactor volume, the treatment capacity increased from 30 000 m3/d to 60 000 m3/d after retrofitting. Concentrations of COD, TP, NH3-N and TN in effluent were (37.7±6.61) mg/L, (0.09±0.03) mg/L, (0.25±0.14) mg/L and (5.87±1.54) mg/L, respectively, which met the first class A standard. Actual operation data indicated that TN removal existed in the aerobic MBBR zone (accounting for 10.36% of total TN removal). Nitrospira was the dominant nitrifying bacteria in the system, and its relative abundance in the suspended carrier and activated sludge was 8.98% and 0.92%, respectively, indicating that the addition of suspended carrier could effectively enrich the nitrifying bacteria. The proportion of denitrifying bacteria on biofilm was 7.94%, which created a micro?environment for the occurrence of simultaneous nitrification and denitrification (SND) in the suspended carrier and improved the TN removal efficiency.
