Abstract

COD (chemical oxygen demand) removal rate and efficiency of winery wastewater (WW) aerobic treatments were evaluated in an air-bubble column bioreactor using self-adapted microbial populations either free or immobilized on polyurethane particles and in a packed-bed bioreactor immobilized on Raschig rings. The bioreactors were fed continuously for up to 12 months using WW of different origins and with different pollution loads (COD range, 0.8-11.0 kg.m(-3)): the maximum loading rate was approx. 8.8 kg-COD m(-3).d(-1). The highest COD removal rate (6.6 kg.m(-3).d(-1)) was obtained with free activated sludge in the bubble column bioreactor; treatment efficiency and hydraulic retention time were >90% and approx. 0.8 d, respectively. The microbial populations in the three reactors were characterized.

摘要

在气泡柱生物反应器中，使用自由的或固定在聚氨酯颗粒上的自适应微生物群落，以及固定在拉西环上的填充床生物反应器，评估了葡萄酒厂废水（WW）好氧处理的化学需氧量（COD）去除率和效率。使用不同来源、不同污染负荷（COD范围为0.8 - 11.0 kg·m⁻³）的葡萄酒厂废水，对生物反应器连续进料长达12个月：最大负荷率约为8.8 kg-COD m⁻³·d⁻¹。在气泡柱生物反应器中，使用自由活性污泥获得了最高的COD去除率（6.6 kg·m⁻³·d⁻¹）；处理效率和水力停留时间分别>90%和约0.8天。对三个反应器中的微生物群落进行了表征。
