摘要: 通过静态水培试验研究塘西河湿地9种常见的水生植物在富营养化水体中的生长状况及对TN、TP、CODcr的去除能力。结果表明:(1)供试的水生植物均能正常生长,石菖蒲在供试植物中生物量增长比达到最高54.36% ,黑藻生物量增长比最低39.14% ;(2)9种植物中石菖蒲对TN的去除率最高可达80.62%,水葫芦最低56.16%;对TP的去除率最高是芦苇可达78.84%,最低是黑藻43.78%;对CODcr的去除率最高是黄菖蒲可达81.60%,最低是黑藻44.76%。初步认为这9种植物中选择黄菖蒲、石菖蒲、芦苇混种可以使水体达到更好的净化效果。

Abstract:  

Through the static hydroponic experiment study of Tangxi River Wetland 9 common aquatic plant growth in eutrophic water and the TN, TP, CODcr removal ability. The results showed that: (1) The aquatic plants could grow in the water, biomass growth ratio is the highest Shi-changpu 54.36%, the lowest is 39.14% of Hydrilla verticillata; (2) 9 kinds of plants on the removal rate of TN is the highest Shi-changpu 80.62%, the lowest is 56.16% water hyacinth; the removal rate of TP is the highest and lowest is 78.84% reeds, Hydrilla verticillata 43.78%; the removal rate of CODcr is the highest in Huang-changpu 81.60%, the lowest is 44.76% of Hydrilla verticillata. Preliminary thought the 9 plants can choose Huang-changpu, Shi-changpu, reed combination can make the water body to achieve better purification effect.
