Wine distillery wastewater, commonly called vinasses, was treated by an anaerobic moving bed biofilm reactor (AMBBR) with 32.9 litre available volume. The reactor was filled with 66% cylindrical polyethylene supports with density 0.84 g cm(-3) as a biofilm carrier. The reactor was sequentially mixed by a submerged centrifugal pump fixed to the bottom, and each mixing time just lasted 1.25 minutes. The organic loading rate (OLR) of the reactor were increased from 1.6 to 29.6 g sCOD l(-1) d(-1) (soluble chemical oxygen demands--sCOD) and hydraulic retention time (HRT) was decreased from 6.33 to 1.55 days accordingly. Soluble COD removal efficiency was 81.3-89.2% at an OLR of 29.6 g sCOD l(-1) d(-1). At the end of the experiment, 83.4% total biomass was attached on support and the specific density of support in the reactor was 0.93-1.05 g cm(-3), which increased by about 10.7-25% compared with that at the beginning of the study.
葡萄酒酿造废水，通常称为酒糟，由一个有效容积为32.9升的厌氧移动床生物膜反应器（AMBBR）进行处理。该反应器填充了66%的圆柱形聚乙烯载体，其密度为0.84克/立方厘米，作为生物膜载体。反应器由固定在底部的潜水离心泵进行顺序混合，每次混合时间仅持续1.25分钟。反应器的有机负荷率（OLR）从1.6克可溶性化学需氧量/升·天（sCOD）提高到29.6克/升·天，相应地水力停留时间（HRT）从6.33天减少到1.55天。在OLR为29.6克/升·天的情况下，可溶性COD去除效率为81.3 - 89.2%。在实验结束时，83.4%的总生物量附着在载体上，反应器中载体的比重为0.93 - 1.05克/立方厘米，与研究开始时相比增加了约10.7 - 25%。
