填料生物滴滤池处理餐厨废水性能研究

为进一步探讨不同生化处理餐厨废水的优缺点，采用生物滴滤池工艺处理相对较低污染的餐厨废水，以提高其处理效果。实验通过研究滴滤池内不同填料，考察了对污染物去除效果，中试结果表明，在反应器启动并稳定运行后，该生物滴滤池对COD、氨氮、总氮和总磷去除率分别为85％、80％、60％和50％，结果表明了不同填料的生物滴滤池均能有效降解餐厨废水，且以松枝处理效果最佳。

Study on Performance of Biofilter for Kitchen Wastewater Treatment

In order to discuss the advantages and disadvantages of the different biochemical treatment methods on kitchen wastewater disposal, this paper adopts biofilter process to improve the effect of kitchen wastewater treatment. This paper studied the different medium in the filter and the effects of pollutants removal. The results of the pilot scale experiment showed that after the start- up period, the removal efficiency of COD, NH4- N, TN, TP reached 85%, 80%, 60% and 50%, respectively. The results indicated that the kitchen wastewater can be degraded effectively by different mediums in the biofiher and the effect of pine biofilter was better than other mediums
