Distillery effluent is a contaminated stream with high chemical oxygen demand (COD) varying from 45,000 to 75,000 mg/l and low pH values of between 4.3 and 5.3. Different processes covering aerobic, anaerobic as well as physico-chemical methods which have been employed to this effluent has been given in this review paper. Among the different methods available, it was found that "An Inverse Anaerobic Fluidization" to be a better choice for treating effluent from molasses-based distillery industries using an inverse anaerobic fluidized-bed reactor (IAFBR). This technology has been widely applied as an effective step in removing 80-85% of the COD in the effluent stream. Therefore, in this review, attention has been paid to highlight in respect of fluidization phenomena, process performance, stability of the system, operating parameters, configuration of inverse anaerobic fluidization and suitable carrier material employed in an inverse anaerobic fluidized-bed reactor especially for treating this effluent.
酿酒厂废水是一种受污染的水流，化学需氧量（COD）很高，在45,000至75,000毫克/升之间，pH值较低，在4.3至5.3之间。本文综述了用于处理这种废水的不同工艺，包括好氧、厌氧以及物理化学方法。在可用的不同方法中，发现“逆厌氧流化”对于使用逆厌氧流化床反应器（IAFBR）处理以糖蜜为原料的酿酒厂废水是一个更好的选择。该技术已被广泛应用，作为去除废水流中80 - 85%的COD的有效步骤。因此，在本综述中，重点关注了逆厌氧流化床反应器中流化现象、工艺性能、系统稳定性、操作参数、逆厌氧流化配置以及用于处理这种废水的合适载体材料。
