| 摘 要： | 规模化猪场废水中含有高浓度的氨氮,如不加以去除,将给环境造成很大的压力。本文分析了国内外现阶段几种去除猪场废水中氨氮的技术:包括物理吹脱、沸石离子交换、还田利用、人工湿地处理、生物硝化反硝化处理。此外,着重介绍了两种极具发展前景的新工艺:短程硝化反硝化、短程硝化--厌氧氨氧化工艺。

| Abstract: | Piggery wastewater with high strength nitrogen is harmful to environment.In this review,Some methods for removal of nitrogen from piggery wastewater were discussed,including ammonias stripping,ammomium uptaking by zeolite,returning to cropland,treatment of wetland,traditional nitrification/denitrification.Furthermore,two most cost-effective processes: sharon,Sharon-anammox were emphatically introduced. |
