| 摘 要： | 本研究分别启动了厌氧膜生物反应器(anaerobic membrane bioreactor, AnMBR)和部分亚硝化-厌氧氨氧化反应器(Partial Nitrification/Anammox, PN/A),两者达到稳态后耦合为"AnMBR+PN/Anammox"新系统,实现前段有机质甲烷化、后段自养脱氮的污水处理目的.耦合系统运行结果表明:化学需氧量(chemical oxygen demand, COD)在AnMBR的去除率为96%,其中80.3%的COD在此段转化为CH_4,Anammox内一定的反硝化作用进一步强化了COD去除,系统COD总去除率达97%以上;氮污染物经AnMBR处理后均以NH~+_4-N形态存在,再经PN/A处理后,总氮(total nitrogen, TN)平均去除率达78%;系统出水COD和TN值分别低于13和11 mg·L~(-1).因此,AnMBR-Anammox耦合系统在同步实现污水甲烷回收、自养脱氮、低碳氮排放方面具有显著优势,本研究结果为开发AnMBR-Anammox耦合新工艺提供了理论依据.

| Abstract: | This study set-up an anaerobic membrane bioreactor (AnMBR) and a partial nitrification-anaerobic ammonia oxidation reactor (PN/Anammox), separately, and then two system were coupled to the "AnMBR+PN/Anammox" to achieve organics removal in AnMBR and post-autotrophic denitrification in PN/A. Results show that the COD removal efficiency in AnMBR was 96%, 80.3% of which was converted into CH4. The total COD removal efficiency of the coupled system exceeded 97% due to the denitrification in PN/A unit. AnMBR converted nitrogen pollutants into NH4+-N because of ammoniation. After PN/A treatment, the average TN removal efficiency was 78%. The COD and TN concentrations in effluent were lower than 13 and 11 mg·L-1, respectively. The AnMBR-Anammox coupled system has significant advantages in simultanous wastewater methane recovery, autotrophic nitrogen removal and low carbon/nitrogen emission. The results of this study provide a theoretical basis for the development of the new AnMBR-Anammox coupling process. |
