摘要 采用中温(34±2℃)全混合式厌氧反应器处理蒽酸和硫化烧碱草浆造纸黑液。对比厌氧发酵结合物化前或后处理两种方法进行试验,厌氧生物降解COD_(er)去除率分别为61.2~75.3%和34.9~46.2%,COD_(er)总去除率分别为80.0~87.6%和68.4~75.8%。在厌氧发酵稳态运行条件下,对发酵污泥中主要微生物类群和数量进行了研究。 Anaerobic reactor was adopted to treat black liquor of anthrance quinone and sulfite alkaline straw pulping. The first experiment method is physical- chemical pretreatment and anaerobic degradation. Anaerobic degradation can remove CODcr by 61.2- 75.3%. The total CODcr removal efficiency is about 80.0-87.6%. The second experiment method is anaerobic degradation and physical,chemical after-treatment. The CODcr removal efficiency is about 34.9-46.2%. The total CODcr removal efficiency is about 68.4--75.80%. When the anaerobic digestion was stable, the main microflora in anaerobic sludge were studied.
