摘要: 分别用玉米秸秆滤料和玉米秸秆–沸石双层滤料对奶牛养殖废水进行吸附–过滤预处理，研究了玉米秸秆滤料和玉米秸秆–沸石双层滤料在不同滤速下对奶牛养殖废水中氨氮、磷及CODcr的去除效果。结果表明玉米秸秆–沸石双层滤料对氨氮、磷及CODcr的去除效果明显优于玉米秸秆滤料。以玉米秸秆–沸石双层滤料为过滤介质，滤速为4 m/h时，氨氮、磷及CODcr的去除率最大，分别为70.85%、46.11%和51.60%。
Abstract: The adsorption-filtration pretreatment of dairy farming wastewater was carried out by using corn stalk filter and corn stalk-zeolite filter. The effects of corn stalk filter and corn stalk-zeolite filter on the removal of ammonia nitrogen, phosphorus and CODcr in dairy farming wastewater were studied under different filtration rates. The results showed that the removal efficiency of ammonia nitrogen, phosphorus and CODcr by corn stalk-zeolite filter was better than that of corn stalk. The removal rate of ammonia nitrogen, phosphorus and CODcr was the highest when the filtration rate was 4 m/h, which was 70.85%, 46.10% and 49.2%, respectively, with corn stalk-zeolite filter as filter medium.
