| 摘 要： | 通过在3种不同基质上种植美人蕉，研究了垂直流美人蕉模拟人工湿地系统对化粪池出水的净化效果以及不同水力负荷对污水净化效果的影响。结果表明，不同填料、不同水力负荷对污水中TP、COD、NH4^ -N、BOD5的净化效果不同。由于美人蕉根系和微生物的吸收与分解作用以及基质的吸附作用，种植美人蕉的人工湿地出水水质要比对照好。

| Abstract: | Canna indica Linn was p la nted in thr ee mixture substrates.The effects o f simulating constructed wetlan d an d hydraulic load on the purifying efficiency for septic tank effluent treat ment were studied in this paper.The results sh owed that the wastewater purifyi ng efficiency for COD,BOD 5 ,ammoniumand total phosphorus were significant different with substra tes a nd hydraulic loading rate.Under the combination functio n of the absorbability and decomposition of Canna indica Linn roots and mi crobiology and the absorptio n of substrate,the effluent quality of vertical-flow constru cted wetlands pl anted with Canna indica Linn were better than those constructed wetlands without Canna indica Linn. |
