摘要
在温室大棚内模拟太湖水质条件下,研究了苦草与伊乐藻不同生物量比例对水质净化作用的影响。研究结果表明,苦草和伊乐藻对水中总氮浓度的去除率可以达到90%以上,通过单因素方差分析得出当苦草和伊乐藻生物量比例为2:1时,水中总磷浓度和CODMN浓度去除率取得最大值,最终确定2:1的生物量比例为最佳种植比例。
The effects of submerged macrophyte at different biomass proportion on water quality were studied. Vallisneria spiralis and Elodea, which were planted in greenhouse, were used in the present study. The water was prepared according to the water quality of Taihu Lake. The results showed that, the removal rate of ρ(TN) more than 90% by Vallisneria spiralis and Elodea. Data were analyzed by one-way ANOVA, the results showed that, the removal rate of ρ(TP) and ρ(CODMN) reached maximum value when the biomass proportion of Vallisneria spiralis and Elodea biomass was 2:1. In summary, 2:1 was the optimum biomass proportion in terms of water quality.
