小葱在污水净化及资源化中的应用效果研究

The potential of Allium ascalonicum L. in purification and reclamation of wastewater

摘要: 本试验采用水培方法研究了小葱(Allium ascalonicum L.)对污水中N、P的生物拦截能力。试验表明，小葱对污水中总N、总P的去除率分别达到98.5%、94.85%，而对照组分别为76.44%、52.96%。在生长期间，小葱吸收固定的N、P分别达11.51g/m²、4.60g/m²，同时可以收获64.9t/hm²的小葱。试验表明小葱不但可以有效的去除水中的N、P，还具有良好的经济价值。

Abstract: The effect of hydroponic Allium ascalonicum L.on the nutrient reduction and reclamation of wastewater was studied in this paper. The results show that the rates of the removed total nitrogen and total phos phorus are 98.5% and 94.85%, respectively, in A. ascalonicum treatments, and 76.44% and 52.96%, respectively, in controls. During the growth period 11.51g/m² nitrogen and 4.60g/m² phosphorus is uptaken by A. ascalonicum L. , and its yield is 64.9t/hm². The result indicates that shallot not only can purify wastewater effectively, but also has obvious good economic value.
