, 2007 以高氨氮、高有机物浓度的养猪场废水为处理对象,在室温(25℃)、不调节pH的条件下,研究了基于厌氧氨氧化(ANAMMOX)的亚硝化过程。结果表明:在进水氨氮浓度约为550mg/L、COD浓度为1 000~1 300 mg/L的条件下,亚硝化效果稳定。反应8~10 h后,出水中的氨氮和亚硝酸盐氮浓度之比可达(1∶1)~(1∶1.20),对氨氮和COD的去除率分别为58.3%~65.6%和59.2%~68.6%,亚硝化率在整个过程中均保持在97%以上。随着曝气量的增大,达到厌氧氨氧化工艺所需进水氨氮 ...

Gongye shui chuli自养反硝化技术具有无需外加碳源、污泥产量低以及成本低等优势，是双碳背景下具有前景的低C/N废水的深度脱氮处理技术之一，而无机电子供体的选择是该技术能否广泛实际应用的关键。根据反硝化原理，硫基自养反硝化易产酸并会产生硫酸盐，铁基反硝化耗酸且会有亚硝酸盐积累，而硫-铁基耦合自养反硝化可以结合两者的特点，维持反应pH稳定，减少二次污染。基于以上分析了硫基、铁基以及硫-铁基作为电子供体的自养反硝化基本作用原理及特性，并阐述了基于各电子供体进行反硝化时的优势菌属，以期为硫基、铁基及硫 ...
