石龙芮与酸模处理生活污水实验研究

Study on Treatment of Domestic Sewage by Poisonous Buttercup and Dock

运用无土栽培技术,通过石龙芮和酸模对生活污水的降解实验,对两种植物作为湿地植物处理生活污水的可行性进行了实验分析。实验表明两种植物对污水中的营养元素都具有较好的去除,N、P元素的最终去除率都能达到80%,石龙芮对COD的去除达到45%左右,而酸模对COD的去除可达50%。相对于单一植物系统来说,石龙芮-酸模复合植物系统可对生活污水中的P元素和COD的去除更高。研究表明石龙芮和酸模都可以作为人工湿地植物,用来处理生活污水,而两种植物都具有耐寒性,可以提高人工湿地在冬季的运行效率。

The treatment of the domestic sewage by Poisonous buttercup and Dock in soilless culture was studied in this paper. The feasibility of the two plants as constructed wetland plants was analyzed. The study results show that both the two plants can remove TN, TP efficiently, with the removal rate about 80%. Compared with unitary plant system, Poisonous buttercup - Dock system showed high removal rate of TP and COD. Results show that treatment for domestic sewage with Poisonous buttercup and Dock is effective. Because both the two plants are cold resistant, they can enhance the wetland＇s efficiency in winter.
