Abstract: In order to investigate hydrophyte role on the purification of pond effluent which was eutrophic,
three hydrophytes ( Phragmites communis Trin., Ceratop hyllum demersum and Trap a quadrisp inosa
Roxb. ) were grown in treated water and as a noneplant to compare effectiveness of nutrient removal. It
can be concluded that all the hydrophytes had a good performance on removal nutrients from treated water
rather than without hydrophyte.After growing thethreehydrophytes 50 days,the total nitrogen ( TN) was
removed by P. communis Trin. (80. 8%) T. quadrisp inosa Roxb.( 62.6%) C. demersum (34.4%) . The
total phosphorus ( T P) was removed by P. communis Trin. ( 73. 2%) C. demersum ( 27. 1%) T.
quadrisp inosa Roxb.( 17.2%) .P. communis Trin. and C. demersum grew better in pond effluent than that
of T. quadrisp inosa Roxb. during experiment period. The average livability of P. communis Trin. and C. de
mersum reached up to 85% and 60% ,respectively.However, T. quadrisp inosa Roxb.only kept under 45%.
For the three hydrophytes growing under the same condition, P. communis
