摘　　要：研究了酒类废水作为污水处理厂反硝化碳源的可行性。首先分析了不同类型酒类废水的物化和微生物群落特征。活性污泥添加酒类废水后,反硝化速率为1.85~2.60 mgNO^(-)_(3)-N/(gVSS.h),效果好于对照组乙酸钠(1.72)。抑制性测试表明添加酒类废水对活性污泥的硝化速率、释磷和吸磷速率均无显著不利影响。残留COD测试表明添加酒类废水对出水COD的影响较小可控。碳源效率测试表明低浓度过滤酒类废水最佳,其碳源消耗质量比(ΔCOD/ΔN)为7.1,低于对照组乙酸钠(10.9)。综上所述,经过适当处理后的酒类废水是优质反硝化碳源。The characteristics of distillery wastewater and its feasibility as denitrification carbon source were discussed in this paper. The components of four types of distillery wastewater were analyzed by systematic scheme, including high-concentration mixed liquor, high-concentration liquor filtrate, low-concentration mixed liquor and low-concentration liquor filtrate. The denitrification rates of activated sludge after dosing the four types distillery wastewater were assessed to be 1.85~2.60 mgNO^(-)_(3)-N/(gVSS·h), which were all higher than the value of dosing acetate at 1.72 mgNO^(-)_(3)-N/(gVSS·h). The inhibitory tests implied that no obvious effects on nitrification, phosphorus release and adsorption process. The dosage of the four types of distillery wastewater had limited effects on the residual COD of effluent wastewater. The carbon/nitrogen utilizing rate(ΔCOD/ΔN) for low-concentration liquor filtrate samples was tested as 7.1, which was lower than that for acetate potassium(10.9). As the summary, distillery wastewater after proper treatment can be used as denitrification carbon source.
