Vinasse is characterized by a high chemical oxygen demand (COD) and dark brown colour, which requires abatement before disposal to prevent the pollution of receiving streams. Anaerobic digestion (AD) usually applied for vinasse treatment can only reduce the COD with the colour remaining unabated. This study investigated the feasibility of combining AD and ozonation for vinasse treatment. The AD process alone achieved high COD removal of 95 %, at a best organic loading rate of 15 kgCOD/m³/d. However, the anaerobic effluent still had an intense dark brown colour caused by a considerable amount of residual biorecalcitrant COD of 4.5 g/L. The ozonation post-treatment of the anaerobic effluent removed 80 % of the colour with up to 92 % ozone transfer at optimal parameters of pH 4, substrate dilution factor of 2, and 90 mg/L/min ozone dosage. Kinetic analysis showed that for a constant feed flow combined system, the ratio of the anaerobic reactor unit to the ozonation reactor unit is recommended to be 20:1. Also, from energy analysis, application of the bioenergy produced from AD to supplement the total energy requirement of the combined system could lead to 50 % savings on energy, and a carbon dioxide emission reduction of 122 kg CO₂/m³ of vinasse treated. The combined system is thus a promising technology for vinasse treatment and can contribute to combating greenhouse gas emissions.

Vinasse具有高化学需氧量（COD）和深棕色的特点，在处置前需要进行减排，以防止污染接收流。通常用于酒糟处理的厌氧消化（AD）只能减少颜色保持不变的COD。这项研究调查了结合AD和臭氧化处理酒糟的可行性。仅AD工艺即可实现95％的高COD去除，最佳有机负载率为15 kgCOD / m ³/ d。但是，厌氧废水仍具有强烈的深棕色，这是由于4.5 g / L的大量残余生物顽固性COD引起的。在最佳参数pH 4，底物稀释系数2和90 mg / L / min臭氧剂量下，厌氧废水的臭氧化后处理去除了80％的颜色，最高转移了92％的臭氧。动力学分析表明，对于恒定的进料流联合系统，厌氧反应器单元与臭氧化反应器单元的比例建议为20：1。同样，从能源分析来看，利用AD生产的生物能源补充组合系统的总能源需求，可以节省50％的能源，并减少122 kg CO ₂ / m ^3的二氧化碳排放量酒糟处理。因此，该组合系统是用于酒糟处理的有前途的技术，可有助于减少温室气体的排放。
