| 摘 要： | 采用臭氧—活性炭联用技术对食品厂废水进行处理,并对臭氧处理时间,臭氧浓度,处理水的流量等因素进行不同水平单因素实验,以找出最佳实验条件,同时结合实际问题,采用L9(34)正交表进行3因素3水平实验,最终得出臭氧—活性炭联用技术处理食品厂污水的最佳工艺条件为:臭氧处理时间为30min,臭氧质量浓度为9.6mg/L,水流量为0.8m3/h。在最佳工艺条件下,臭氧—活性炭结合工艺对COD的去除率为89.8%,对UV254的去除率为97.3%,达到了农田灌溉水质(水作和旱作的灌溉)标准,基本达到蔬菜灌溉用水的标准。

| Abstract: | Ozone in conjunction with activated carbon has been applied to treat the food wastewater. Treatment time,ozone concentration and water flow rate were optimized through single factor test,and finally scope of the optimum conditions were established. At the same time, regarding to practical problem, using above factors to establish different level, using orthogonal table L9 (34) to do three factor and three level test. The results of orthogonal experiment show the optimum technological conditions are as follo... |
