摘　　要：根据污水处理所用填料的技术特征,自行开发研制了一种新型组合填料.通过平行实验测定了亏氧清水中该组合填料和其他3种填料塔的氧液相体积传质系数,并进行了比较.结果表明该组合填料具有优良的氧传递性能.对实验结果进行回归分析,得到4种填料氧传质系数的计算式,其计算值与实测值基本吻合.最后对同种填料在相同操作条件下,对亏氧清水和餐厅污水中的氧传递实测结果进行了比较.结果表明餐厅污水中的氧传质系数小于亏氧清水中的氧传质系数.A new-style combined packing was developed. The oxygen transfer features of this kind packing as well as other three kinds packings in water or restaurant wastewater were studied by paralled experiments. The results showed that the new-style combined packing is superior to the other three kinds of packings in oxygen transfer, and the equations for calculating liquid-phase volumetric oxygen transfer coefficient in water and restaurant wastewater were obtained by correlating the experimental data wherein deviations are within 20%. The comparison of oxygen transfer in water with that in restaurant wastewater when other conditions remained the same showed that volumetric oxygen transfer coefficients in restaurant wastewater was smaller than those in water.
