以 LSAR 为载体的 UAFB 反应器运行动力学

KINETICS OF UAFB REACTOR WITH SPHERIC LIGNOSULFO NATE RESIN AS BIO-MICROCARRIER

以用造纸黑液制成的球形木质素树脂作为生物载体，在上流式厌氧流化床（ＵＡＦＢ）反应器装置中，进行了处理模拟高浓度酸化相出水的厌氧甲烷相流化床的运行实验．结果表明，当有机容积负荷小于６．０ｇ／（Ｌ·ｄ）时，基质ＣＯＤ去除率高于９０％；实验中得到生物负载量为０．０７４５；建立了ＵＡＦＢ反应器的动力学模型，测定了３５℃时的动力学参数．

Spheric Lignosulfonate Resin(LSAR) produced by sulfite process waste liquid dischanged in papermills was used as bio_microcarrier in laboratory_scale up flow anaerobic fluidized bed (UAFB) reactor. The UAFB reactor was introduced to the methane phase with synthetic high concentration acetate solution as sole substrate. Under pesudo_steady_state condition at an organic loading of 6.0 g/(L·d), the matrix COD removal rate is up to 90%. The bio_capaticy of LSAR is 0.074 5. The kinetic model of UAFB was established and a set of kinetic parameters were evaluated at 35 ℃.
