摘要:
以晚期垃圾渗滤液为研究对象,考察ANAMMOX-UASB系统脱氮性能及ANAMMOX颗粒污泥表观特性和粒径分布变化.结果表明,采用ANAMMOX-UASB系统处理晚期垃圾渗滤液可实现高效脱氮.在稳定期,NH+4-N, NO-2-N和TN的平均去除率分别为96%,95%和87%;系统中ANAMMOX颗粒污泥厌氧氨氧化活性良好,仍然是脱氮的主要途径;同时也有部分异养反硝化作用同步脱氮.此外,系统中还存在好氧氨氧化和亚硝氮氧化作用,其活性分别为0.031和0.010 g/(g·d).系统中颗粒污泥颜色由砖红色转变成红褐色,平均粒径由小变大;稳定运行期粒径大于1.5 mm的颗粒污泥为81%;颗粒污泥表层有球菌、杆菌和丝状菌附着.
Abstract:
Taking the mature landfill leachate as the research object, the nitrogen removal performance of the ANAMMOX-UASB(anaerobic ammonia oxidation up-flow anaerobic sludge blanket)system, the ANAMMOX granular sludge characteristics, and the changes of its size distributions were investigated. The results show that the ANAMMOX-UASB system can achieve efficient nitrogen removal in mature landfill leachate. At the stable stage, the average removal rates of NH+4-N, NO-2-N and TN were 96%, 95% and 87%, respectively. The activity of ANAMMOX granular sludge was very well, and ANAMMOX still was the main way of nitrogen removal, but there was also nitrogen removal by heterotrophic denitrification simultaneously in the system. Moreover, aerobic ammonia oxidation and nitrite oxidation existed in the system, and their activity were 0.031 and 0.010 g/(g·d), respectively. The color of granular sludge changed from brick red to red-brown, and the average size of granular sludge changed from small to large. At the stable stage, the proportion of granular sludge size exceeding 1.5 mm was 81%. There were spherical bacteria, rod-shaped bacteria and filamentous bacteria on the granular sludge surface.
