Qutdoors experiment was performed to find out optimal wastewater flow rate and planted density of waterhyacinth. The mutual planted with three plants to purity wastewater, The removal ability of three plants were compared in the greenhouse ,the search results were show as follow:1) 22.5kg/m2 planted density had higher removal pollutant ability than 5~12.5kg/m2.2) If the low planted density was culture, wastewater inflow to pond can with pilot method.3) The average removal rate had 38.1% NH4+-N,50%T-N,12.8% PO43--P,12.0% T-P with 2.25m3/d inflow, whereas that had 80.3%, 71.0%, 34.4%,19.4% removal rate when inflow was down to 1.13m3/ day. 4) The Same 2.25m3/day inflow rate, but waterhyacinth planted density was up to 22.5 kg-fresh weight/m2, so 88.8%NH4+- N, 83.3%T-N, 87.5%PO43--P, 96.5%SS, 80%BOD was removed. 5) The total removal rate had 100%NH4+-N, 90.2%T-N, 98.8%SS, 80~90% PO43--P,BOD, whereas water lettuce were also planted.6) The greenhouse experiment result showed: the average unit area removal rate was high in waterhyacinth pond, next was water lettuce, the duckweed was low, but the duckweed had higher absorption rate of wastewater than water lettuce.7) The average unit weigh can remove pollutants, The duckweed plant had high capability to N,P,EC, but waterhyacinth, and water lettuce had better efficacy to BOD, Because due to their larger root surface area to adsorb microorganism. 8) The mutual planted aquatic plants in field pond had high removal ability than the other experiments and greenhouse tryout. it had 1.34g-T-N/m2.d. 0.99g-NH4+-N/m2.d, 0.31g-PO43-P removal ability.

碩士 === 淡江大學 === 水資源及環境工程學系 === 86 === Three aquatic plants contain waterhyacinth, duckweed and water
lettuce were used to purity wastewater in this study, this study
was proceeded with outdoors and greenhouse experiments. Qutdoors
experiment was performed to find out optimal wastewater flow
rate and planted density of waterhyacinth. The mutual planted
with three plants to purity wastewater, The removal ability of
three plants were compared in the greenhouse ,the search results
were show as follow:1) 22.5kg/m2 planted density had higher
removal pollutant ability than 5~12.5kg/m2.2) If the low planted
density was culture, wastewater inflow to pond can with pilot
method.3) The average removal rate had 38.1% NH4+-N,50%T-N,12.8%
PO43--P,12.0% T-P with 2.25m3/d inflow, whereas that had 80.3%,
71.0%, 34.4%,19.4% removal rate when inflow was down to 1.13m3/
day. 4) The Same 2.25m3/day inflow rate, but waterhyacinth
planted density was up to 22.5 kg-fresh weight/m2, so 88.8%NH4+-
N, 83.3%T-N, 87.5%PO43--P, 96.5%SS, 80%BOD was removed. 5) The
total removal rate had 100%NH4+-N, 90.2%T-N, 98.8%SS, 80~90%
PO43--P,BOD, whereas water lettuce were also planted.6) The
greenhouse experiment result showed: the average unit area
removal rate was high in waterhyacinth pond, next was water
lettuce, the duckweed was low, but the duckweed had higher
absorption rate of wastewater than water lettuce.7) The average
unit weigh can remove pollutants, The duckweed plant had high
capability to N,P,EC, but waterhyacinth, and water lettuce had
better efficacy to BOD, Because due to their larger root surface
area to adsorb microorganism. 8) The mutual planted aquatic
plants in field pond had high removal ability than the other
experiments and greenhouse tryout. it had 1.34g-T-N/m2.d.
0.99g-NH4+-N/m2.d, 0.31g-PO43-P removal ability.
