摘 要: 与传统的生物硝化-反硝化工艺相比,亚硝化-厌氧氨氧化联合工艺在处理低(超低)碳氮比高浓度含氮废水方面有着不可替代的优越性,是上个世纪末生物脱氮领域里的一个突出的创新.在温度为30~40℃和水力停留时间约为1 d条件下,p(DO)在0.5~2.5 mg/L,pH值为7.4~8.3时,能够较好的实现匹配厌氧氨氧化的亚硝化;探讨了亚硝化和厌氧氨氧化在污泥颗粒化技术中的实现可能机理. Compared to the conventional biological nitrification-denitrification process, the combined SHARON-ANAMMOX process has irreplaceable superiority in treating high-concentration and nitrogen-containing wastewater featuring low (ultralow) m(C)/m(N) ratio, and is a novel innovation in the field of biological denitrification at the end of last century. Under the conditions that temperature is 30 ~ 40℃ and hydraulic residence time is 1 day, when ρ(DO) is 0.5 ~ 2.5 mg/L and the pH value is 7.4 ~ 8.3, nitrosation matching ANAMMOX can be better realized. The possible mechanism of the realization of the SHARON-ANAMMOX process in sludge granulation technology is also discussed.
