| 摘 要： | 凤眼莲是优良的污水净化植物,凤眼莲死亡后残体对水质的影响制约了其应用.在凤眼莲衰亡后,调查研究凤眼莲死亡对自然水体水质的影响,结果表明,在凤眼莲的衰亡期,其对富营养化水体的透明度、CODMn、TN、TP、NH4 -N等指标仍然具有改善作用;在后续影响期(次年春季),在有凤眼莲死亡腐烂的水体中,除了水体TN浓度呈现增加趋势外,其他主要水质指标的浓度变化均不明显.

| Abstract: | Eichhornia crassipes is qualified for purifying wastewater. But its application was limited by the second pollution of decaying waterhyacinth on water quality. The influence of decaying waterhyacinth was investigated in two enclosures. The results showed that during the first period, its remains floated on the water surface, the concentration of COD_(Mn), TN, TP and NH_4~ _N in the experimental enclosure with waterhyacinths were lower than that in the control enclosure without waterhyacinths and the water transparency was higher in the experimental enclosure. Total nitrogen was higher in the experimental enclosure slightly than that in the control enclosure after the remains dropped down into the bottom. |
