美人蕉/香根草植物浮床体系脱氮除磷效果研究
|
摘要
研究了美人蕉和香根草植物浮床体系对实验水样中氨氮、总磷、COD等的去除效果。结果表明:移植到浮床体系后,美人蕉和香根草均表现出良好的生长能力。在吸收、吸附和微生物降解的共同作用下,第8周后两者的脱氮除磷效果达到最佳,其中美人蕉对氨氮和总磷的最高去除率分别为65. 56%和67. 78%,香根草对氨氮和总磷的最高去除率分别为67. 78%和64. 50%。
The removal effects of ammonia nitrogen,total phosphorus and COD by a canna and vetiver floating bed system were investigated. The results showed that both of them showed good growth ability after transplantation into the floating bed system. Under the combined action of absorption and microbial degradation,the optimal removal effects of nitrogen and total phosphorus was achieved after 8 weeks. The highest removal rates of ammonia nitrogen and total phosphorus by the canna were 65. 56%and 67. 78% respectively,and those by the vetiver grass were 67. 78% and 64. 50% respectively.
