摘要
综述了糖蜜酒精废水的现行治理技术,分析了农田灌溉法、浓缩法、厌氧-好氧法和EM技术处理糖蜜酒精废水的优缺点,同时提出了用微氧技术处理糖蜜酒精废水的新方法,介绍了微氧技术的研究状况及其在处理糖蜜酒精废水方面的优势。试验结果表明,利用微氧厌氧技术处理富含硫酸盐糖蜜酒精废水是切实可行的,该技术不仅可有效去除废水中的有机质和硫酸盐,还为实现单质硫和沼气资源的回收利用创造条件。
The techniques currently used for molasses distillery wastewater treatment are summarized. The advantages and disadvantages are analyzed on the irrigation cropland method, concentrated method, anaerobes-aerobic method and EM technology used for molasses distillery wastewater treatment. A new method using oxygen-limited anaerobic process is tested, and the results show that it is practical and feasible for the treatment of high-sulfate molasses distillery wastewater. With the new method,the COD and sulfate can be effectively removed, and it is possible to reuse the sulfur and methane.
