中文摘要：
菖蒲对废水具有较好的净化效果,水葱、酸模、鸢尾对废水也有一定的净化效果,将寻找一种挺水植物与菖蒲的组合对畜禽产品废水具有更好的净化效果,从而在生产上推广应用。选择菖蒲与水葱、酸模、鸢尾组合的3个试验组,只有洗沙的无植物空白试验作为对照组,测定试验前后的9个指标。试验结果表明：对畜禽产品加工废水处理过程中,所选3种组合生长良好并表现出较好的三氮、氮磷及COD净化效果。其中,菖蒲＋鸢尾对NH3-N、NO2-N的净化效果最好,去除率分别为90.35%、51.91%;菖蒲＋酸模对NO3-N的净化效果最好,去除率为14.24%。相对空白对照的去除率,菖蒲＋水葱的总磷净化性能最好,提高4%;菖蒲＋酸模组、菖蒲＋鸢尾组COD净化性能最好,分别提高0.36%、0.29%。
英文摘要：
Acorus calamus had good purification effect on the waste water,scirpus validus,rumex acetosa and iris tectorum had purification effect.The best combination with Acorus calamus would be found with good purification effect on the waste water from livestock and poultry products,that would be popularized and applied in production.Both Acorus calamus and the other three plants,including Scirpus validus,Rumex acetosa,Iris tectorum,respectively were chosen as experimental group,blank test with sand and without plant was chosen as matched group.The 9 index before and after test were determined.The results showed that all of plants of the selected 3 combination grew well in the waste water and had good removal efficiency of 3 types of nitrogen,nitrogen and phosphorus,and COD.The best of purification ability of ammonia nitrogen and nitrite nitrogen was the combination of Iris-calamus,the degradation rate of 90.35%,51.91%.Iris-Rumex had the best purification ability of,nitrate nitrogen from the livestock and poultry products effluent with the degradation rate of 14.24%.Among combinations of 3 kinds of plants,Acorus calamus and Scirpus validus had the highest removal efficiency on total phosphorus purification compared with the control group,the average TP removal rate was increased by 4% as well.Acorusand Irisacid modules,Acorus and Rumex had the highest removal efficiency on COD purification compared with the control group,and the average COD removal rate were increased by 0.36% and 0.29%,respectively.
