| 摘 要： | 通过长期运行实验,对比研究了气水交替膜生物反应器(gas-water alternative membrane bioreactor,AMBR)和传统淹没式膜生物反应器(submerged membrane bioreactor,SMBR)对模拟生活污水的处理效果.结果表明,两反应器对COD和NH4+-N的去除效果较为类似,去除率均高于96%;SMBR对污染物的去除作用以混合液中的活性污泥为主,而AMBR混合液中的活性污泥量很少,污染物的去除主要依靠附着于中空纤维膜表面微生物的作用.但AMBR比SMBR具有明显的反硝化脱氮优势,AMBR对TN的去除率为76.94%,远高于SMBR的52.41%.此外,通过两反应器长期运行过膜阻力变化规律的研究发现,AMBR比SMBR具有更好的抗膜污染能力.

| Abstract: | A bench-scale comparative study between gas-water alternative membrane bioreactor(AMBR) and traditional submerged membrane bioreactor(SMBR) treating synthetic municipal wastewater was conducted with respect to the effects of carbon and nitrogen removal and membrane fouling.The results showed that both the AMBR and the SMBR had very good removal in COD and(NH~+_4-N) of more than 96%.In SMBR,carbon and nitrogen removal was enabled by biomass in bulk liquid,while in AMBR,it was supposed to be functioned mainly... |
