利用动态膜生物反应器单元和复合式垂直流人工湿地单元组成一个复合系统来处理生活污水。研究了系统和各单元对COD,NH4^+-N,以及浊度的去除效果,结果表明,系统对它们的总去除率分别为93.35%,97.30%和92.13%;研究了膜易污染情况下膜通量的衰减,分别用0.5%,0.5%,0.1%NaOH溶液5h、10h,10h反冲洗膜,可以使膜通量由原来的43.90%,35.79%和53.50%分别恢复到了87.49%.92.87%和89.48%。
The dynamic membrane bioreactor unit was combined with the integrated vertical-flow constructed wetland as a hybrid system to cope with domestic sewage. The average removal efficiency of COD, NH4^-N, and Turbidity from the hybrid system and each single unit were studied, and the results indicated that the total average removal rates were 93.35%, 97.30% and 92.13% respectively ,were the total average removal rate that made by the system. The attenuation of membrane flux when membrane easily contaminated were also discussed, and membrane flux were made from 43.90%, 35.79%, and 53.50% to 87.49%, 92.87% , and 84.4% alternatively by different means and durations of cleaning, which were 5h with 0.5%NaOH,10h with 0.5%NaOH,and 10h with 0.1%NaOH.
