铜锈环棱螺对水体中叶绿素a的去除作用
Removal of Chlorophyll a from Water by Bellamya aeruginosa
摘要: 本文通过室内水箱建立短时间(72 h)和较长时间(15 d)的模拟实验，探究铜锈环棱螺对富营养化水体叶绿素a和总氮、总磷的去除作用。实验结果表明铜锈环棱螺对叶绿素a有较为明显的去除作用，短时组(72 h)对叶绿素a平均去除率为55.13%，长时组(15 d)对叶绿素a的平均去除率为98.31%。两组对总氮没有明显的去除作用反而会使水体总氮上升；长时组(15 d)总磷平均上升5.036%；而短时组(72 h)总磷水平呈现先下降再上升且第8 d总磷水平小于初始值，证明此系统可以在短时间内降低总磷水平。
Abstract: In this paper, short-term (72 h) and long-term (15 d) simulation experiments were established in indoor water tanks to explore the removal of chlorophyll a, total nitrogen and total phosphorus in eutrophic water. The results of the experiment show that Bellamya aeruginosa has a relatively ob-vious removal effect on chlorophyll a. The average removal rate of chlorophyll a in the short-term group (72 h) is 55.13%, and the average removal rate of chlorophyll a in the long-term group (15 d) is 98.31%. The two groups had no obvious removal effect on total nitrogen, but would increase the total nitrogen in the water body; the long-term group’s (15 d) total phosphorus increased by an average of 5.036%; while the short-term group’s (72 h) total phosphorus level first decreased and then increased, and the 8 d total phosphorus level was less than the initial value, which proves that this system can reduce the total phosphorus level in a short time.
