| 摘 要： | 研究了间歇投加微生物絮凝剂MBF21和阳离子PAM对厌氧污泥颗粒化的作用规律在此基础上考察了污泥的比生物絮凝因子与厌氧污泥的粒径间的关系.研究表明,污泥的比生物絮凝因子与污泥的粒径呈正相关微生物絮凝剂组、阳离子PAM组及对照组中厌氧污泥的比生物絮凝因子BF/BF0分别增加至42.65、40.45、21.89;与对照组相比,微生物絮凝剂组和阳离子PAM组污泥的BF/BF0分别提高了94.8%和84.8%.相应的污泥平均粒径分别增加至1.04、1.13、0.63mm;与对照组相比,微生物絮凝剂组和阳离子PAM组的污泥平均粒径分别增加了65.1%和79.4%.

| Abstract: | The effect of bioflocculant MBF21 and cationic PAM with intermittent addition on anaerobic sludge bioflocculation in the UASB reactor was studied, compared with the reactor without any flocculants addition. Moreover, the connection between relative bioflocculant parameter BF/BF0 and the size of anaerobic granule was explored. The experimental results showed that the BF/BF0 value of sludge in the bioflocculant-added reactor, cationic PAM-added reactor and control reactor increased to 42.65, 40.45 and 21.89, respectively. The BF/BF0 values of sludge in the bioflocculant-added reactor and the cationic PAM-added reactor increased by 94.8 % and 84.8 % compared with the control reactor. The diameter of granules in each reactor increased to 1.04, 1.13 and 0.63 mm, respectively ; The diameter of granules in the bioflocculant-added reactor and the cationic PAM-added reactor increased by 65.1% and 79.4% compared with control reactor. |
