[目的]探索有效去除猪场废水中有机物和氨氮的最佳途径.[方法]在1t废水中添加1.4 kg的石灰,考察石灰对猪场废水中化学需氧量(COD)、总磷(TP)和氨氮的去除效果.[结果]石灰对废水中COD的去除率在20％左右,对TP的去除率在50％左右,但对氨氮的去除效果不理想.[结论]该研究为猪场废水的有效处理提供了一定的依据.%[Objective] The aim was to explore ihe best way to effectively remove the organic compounds and ammonia nitrogen of piggery wastewater. [Method] 1.4 kg lime was added into 1 t piggeiy wastewater, the removal effect of COD, TP and ammonia nitrogen of piggery wastewater was investigated. [Result] The removal efficiency of COD and TP were about 20% and 50% respectively, but lime was not an ideal choice to remove ammonia nitrogen of piggery wastewater. [ Conclusion j The sludy provides a basis for the effective treatment of piggery wastewatei.
