动物修复技术对城市景观水体的修复研究

Remediation of water body of urban landscape by animal repair technology

本实验采用野外自然放养的方法,研究景观金鱼及家鸭对富营养化水体的净化作用,定期采集水样并检测水体指标。研究结果表明:景观金鱼及家鸭对富营养化水体均有一定净化效果,水体中的TP、TN、叶绿素a都大幅度下降,水体透明度提高,水体生态功能得到初步恢复;其中金鱼对富营养化水体的综合处理效果最好,其对TN的处理效果达到63.6%,对TP的处理效果达到78.7%,对chla的处理效果达到88.7%。

Taking the method of wild natural stocking, the paper studied the purification effect of land- scape goldfish and domestic ducks on eutrophication and collected water sample and detected the index of water body. The results showed that the landscape goldfish and domestic ducks have a certain purification effect on eutrophic water body, TP, TN and the Chlorophyll a in the water drop significantly and the wa- ter transparency is improved, and the water ecological function is recovered preliminarily, whereby, the best comprehensive treatment effect on eutrophic water body is goldfish whose treatment effect on TN, TP and Chlorophyll a reached 63.6% , 78.7% and 88.7% respectively.
