| 摘 要： | 采用序批式反应器(SBR)与间歇曝气膜生物反应器(IAMBR)处理模拟生活污水,考察了进水盐度对两反应器污水处理效果的影响。研究表明,当进水盐度为0g/L(以NaCl质量浓度计,下同)时,SBR和IAMBR对总有机碳(TOC)、NH4+-N及TN的去除能力相当,IAMBR未表现出明显的优势;当进水盐度为10g/L时,SBR和IAMBR对TOC、NH4+-N及TN的去除产生明显的差异。IAMBR因为膜的截留与微生物富集作用,对污染物的去除无明显变化,依然保持了较高的污染物去除率,而SBR受盐度冲击影响较大,TOC、NH4+-N及TN的去除率均大幅降低,说明IAMBR具有较高的抗盐度冲击性能。

| Abstract: | The sequencing batch reactor(SBR) and intermittently aerated membrane bioreactor(IAMBR) were applied for treatment of simulated wastewater,and the effect of salinity on the treatment performance of two reactors was investigated.The results showed that when the salinity level(counted by NaCl concentration) was 0 g/L,both IAMBR and SBR presented excellent TOC,NH+4-N and TN removal efficiency,IAMBR had no significant advantage over SBR.However,significant decreases of TOC,NH+4-N and TN removal were observed in the SBR under salinity of 10 g/L,while in the IAMBR,the performance was still stable.The IAMBR exhibited a high tolerance to salinity. |
