摘　　要：采用人工快渗系统处理高浓度模拟养殖废水,考察了不同工艺参数对污染物去除效果的影响。结果表明,与天然细砂、粗砂相比,天然中砂是最佳渗滤介质,且加入一定比例的大理石砂可以提高对氨氮的去除效果;在试验条件下,人工快渗系统的最大水力负荷为0.26 m/d,最佳运行方式为淹水1 d、落干2 d。Taking high concentration livestock wastewater as research object, the removal efficien- cy of pollutants by different infiltration media and the optimal hydraulic loading and operation mode were investigated. The results show that natural medium sands with moderate size is appropriate filtration media, and adding marble can improve the removal rate of ammonia nitrogen. Under the experimental conditions, the constructed rapid infiltration system operates at the largest hydraulic loading of 0.26 m/d, and the most suitable operation mode is the flooding for one day and drying for two days.
