Abstract:

分别采用炭纤维(CF)和活性炭纤维(ACF)作为固定床厌氧反应器的生物膜载体,以不加任何载体的相同规格的反应器为对照,在中温(35±1)℃、连续进料条件下处理高浓度糖蜜废水,实验历时165d,比较评价了2种不同性能的炭纤维作为载体的固定床厌氧反应器的运行性能。结果表明,CF和ACF均是较好的微生物附着的载体材料,具有较强的处理高负荷有机废水和抵抗pH冲击的能力,能显著地提高反应器运行系统的稳定性。具有高比表面积的ACF较之CF更易于微生物固着并挂膜。对照在进水COD超过20000mg/L,相应OLR为8.35kgCOD/(m3·d)时,系统开始酸化。而以CF和ACF为载体的反应器能在进水COD高达70000mg/L,相应的OLR分别为36.85和39.06kgCOD/(m3·d)的高有机负荷下运行,且系统的pH更稳定。对照及以CF和ACF为载体的反应器的最高容积产气率分别为4.33、17.12和16.12m3/(m3·d);165d的累积产气量分别为5665.4、22675.8和26112.8L,后2者的产气量分别是对照产气量的4.0和4.6倍。
