摘　　要：在接藻和无藻条件下,研究猪场厌氧废液中有机物、氮、磷等污染物的去除效果。结果表明,藻对NH3-N,TN,TP,色度的去除效果均比较好,尤其对NH3-N,TN的去除率分别达到97.5%和95.0%;而对COD的净化效果不明显;藻类的存在会使废液的p H值偏高。Anaerobically digested effluent of swine wastewater were treated with or without algae, and the removal efllciencies of organic matter, nitrogen, phosphorus were determined. Results showed that the algae had good performances in NH3-N, TN and TP removal, particularly for NH3-N and TN, the removal efficiencies reached 97.5% and 95.5% respectively. However, the algae showed no obvious purification effect on COD removal. And the presence of the algae may cause pH value of effluent on the higher side.
