曝气生物滤池处理啤酒废水的研究

Study on the Treatment of Brewery Wastewaterwith Biological Aerated Filter

曝气生物滤池使用了新型的粒状填料，能同时发挥生物降解、过滤和吸附等多种功能．实验结果表明：曝气生物滤池处理啤酒废水效果较好，当ＣＯＤ容积负荷为１０ｋｇ／（ｍ３·ｄ）时，在０．８ｍ／ｈ、１．４ｍ／ｈ和２．５ｍ／ｈ３种不同水力负荷下ＣＯＤ的出水浓度分别在５９ｍｇ／Ｌ、８２ｍｇ／Ｌ和５１ｍｇ／Ｌ以下；当ＢＯＤ容积负荷为６ｋｇ／（ｍ３·ｄ）时，３种水力负荷下的ＢＯＤ５出水浓度分别在２１ｍｇ／Ｌ，３８ｍｇ／Ｌ，２４ｍｇ／Ｌ以下．分析结果表明，出水浓度随容积负荷的增高而增高。

The biggest characteristic of the biological aerated filter(BAF) is using a kind of granular media.The research results show that the performance of the brewery wastewater treatment with BAF is excellent.When COD volumetric loading is 10kg/(m3d),under the hydraulic rate of 08m/h14m/h and 25m/h,the COD concentration of effluent is below 59mg/L82mg/L and 51mg/L respectively,and the BOD5 concentration of effluent is below 21mg/L38mg/L and 24mg/L when BOD5 loading is 6kg/(m3d).This research also get the conclusion that the effluent COD concentration increases linearly with the organic load.
