摘要
采用稀释和两段厌氧发酵工艺处理糖蜜酒精废水，试图消除硫酸盐还原产物H2S对厌氧微生物的影响，提高废水处理效率。结果表明，在35℃条件下，发酵系统容积负荷率为5．3gCOD／（L.d），容积产沼气率达2．03L／（L．d），废水化学耗氧量（COD）去除率达69．5％。处理1m3废水（COD值100000mg／L）可生产沼气38m3。
Molasses waste water from the sugar refinery were treated by using dilution and anaerobic fermentation process in laboratory. Results showed that the organic loading for the fermentation system was 5. 3 COD/L/d,volumetric biogas 2.03 L/L/d,and COD removal 69.5%, Treatment of 1 m3 waste water(COD 10 0000 mg/l)produced 38 m3 biogas.
