The algae removal characters by hydroponic bio-filter method (HBFM) were studied applying ecological water area isolation (mesocosm) technique simulating and reappearing small enclosed water body surroundings. The average removal rate of algae reached 61.1% and the removal effect of Microcystis sp. was distinct especially. By means of constructing a mathematical ecological model for computer simulation, it was obtained that Chl.a concentration in enclosed water body reduced from 100 μg/L to 10 μg/L in 45 days by HBFM when the circular ratio (day treatment water amount/enclosed water body capacity) was 0.2.
