摘　　要：通过将高效脱氮细菌包埋在废旧纺织布表面,形成高生物量的柔性多孔填料,投加到移动床生物膜反应器MBBR中,探究不同HRT和包埋菌量对MBBR处理水产养殖废水的强化处理效能。结果表明:投加菌量为80 ml,HRT为8h时脱氮处理效果最好,TN去除率达到98.94%,NO2−-N的积累量仅为0.11 mg/L;包埋菌在脱氮过程起着主要作用,其他硝化和反硝化生物种群丰度随时间逐渐增加。采用该工艺净化水产养殖废水具有可行性和实用性。A flexible porous filler with high biomass was formed by embedding high-efficiency denitrification bacteria on the surface of waste textile cloth, and then added to the moving bed biofilm reactor (MBBR) to investigate the enhanced treatment efficiency of aquaculture wastewater treated by MBBR with different HRT and embedding bacteria. The results showed that the nitrogen removal rate reached 98.94%, and the accumulation ofNO2−-Nwas only 0.11 mg/L when the bacteria dosage was 80ml and HRT was 8h,. The embedded bacteria played a major role in the nitrogen removal process, and the abundance of other nitrifying and denitrifying organisms increased gradually with time. It is feasible and practical to purify aquaculture wastewater by this process.
