摘  要:
[目的]研究浮萍和金鱼藻对生活污水的净化效果。[方法]构建小型水培污水净化系统,以浮萍和金鱼藻2种水生植物为研究对象,研究其在不同水培时间下对生活污水的净化效果,并设置空白对照组进行比较分析。[结果]经过28 d的试验研究,结果表明:浮萍系统对生活污水COD、NH3-N、TN、TP的最终去除率分别为80.8%、92.4%、89.7%、85.3%,金鱼藻系统对生活污水COD、NH3-N、TN、TP的最终去除率分别为79.5%、92.1%、88.6%、86.9%,对照组中COD、NH3-N、TN、TP的最终去除率分别为71.8%、76.5%、75.4%、59.8%。[结论]浮萍和金鱼藻对生活污水净化效果良好,在水培污水净化系统中具有重要作用。

摘  要:
[Objective] To study purification effect of duckweed and hornwort on domestic sewage.[Method]A small hydroponic sewage purification system was constructed. With duckweed and hornwort as research object,the purification effects on domestic sewage in different time were tested,and blank control group was set up for comparative analysis.[Result] After 28 d,the experimental study showed that: the final removal rates of duckweed system on COD,NH3-N,TN,TP were 80. 8%,92. 4%,89. 7% and 85. 3% respectively,that of hornwort system on COD,NH3-N,TN and TP were 79. 5%,92. 1%,88. 6% and 86. 9% respectively,and in the control group,the final removal efficiency on COD,NH3-N,TN and TP were 71. 8%,76. 5%,75. 4% and 59. 8% respectively.[Conclusion] Duckweed and hornwort has good purification effect on domestic sewage,plants play an important role in hydroponic sewage purification system.
