甘蔗制糖废水零排放的工程实践

Practice of Wastewater Zero-Discharge in Canesugar Production

传统制糖生产中废水综合治理和利用方面比较粗放,水污染及资源浪费严重。本文介绍了甘蔗制糖废水的闭合循环综合利用系统,使生产中工艺用水及非工艺用水得到分类处理和循环利用,实现了生产用水零取水,工艺废水零排放。

The comprehensive treatment and usage of wastewater during traditional sugar production are extensive, which leads to severe water pollution and waste of resources. In this study, a circulating method to comprehensively use the waste water from the production of cane sugar was described. By using this method, water used both in and out of process could be classificatorily treated and recycled, and as a result, the amounts of fresh water used for sugar production and waste water discharged into the environment are all zero.
