Abstract

This work investigated how thermal and chemical pretreatments influenced the anaerobic ammonium oxidation process in anaerobic digestion using biogranules that had been acclimated to septage. The digestion experiments were performed in serum vials using thermally and chemically pretreated septage as the substrate. The experimental results indicated that heat pretreatment reduced both dinitrogen production and ammonium removal. HCl and NaOH pretreatments increased both values by near 45% and 55% over the control. Alkali addition was more efficient than acid addition in enhancing dinitrogen production and ammonium removal.

摘要

本研究探讨了热预处理和化学预处理如何影响利用已适应污泥消化液的生物颗粒进行厌氧消化过程中的厌氧氨氧化工艺。消化实验在血清瓶中进行，使用经热预处理和化学预处理的污泥消化液作为底物。实验结果表明，热预处理降低了二氮产量和铵去除率。与对照相比，HCl和NaOH预处理使这两个值分别提高了近45%和55%。在提高二氮产量和铵去除率方面，添加碱比添加酸更有效。
