[Objective]To study the effect of bio-filer to treat wastewater. [ Method] The bio-filter was hung in the aquarium close to windowsrnfor treatment of wastewater from in intensive fish pond. Four test groups were designed in the experiment; controlled group (no bio-filter) ,rnNo. 1 group (5 bundles of bio-filter) , No. 2 group (10 bundles of bio-filter) and No. 3 group (15 bundles of bio-filter) , the purificating effectrnof bio-filter on water quality and optimal configuration were studued. [Result] The bio-filter was effective on the removal of total nitrogen andrnnitrite nitrogen, and on improving DO. Through analysis of water quality parameters, No. 2 group showed the best effect on water purification.rn[ Conclusion] Bio-filter was effective on wastewater treatment of intensive fish pond. The optimal density of bio-filter in the indoor experimentrnfor water purification was 0.07 bundles /L (water).%[目的]研究生物刷净化废水的效果.[方法]通过在临窗水族箱内吊挂生物刷的方法来净化精养池塘的废水.设置了对照组(无生物刷)、试验组①(5串生物刷)、试验组②(10串生物刷)和试验组③(15串生物刷),研究生物刷对水质的改善作用和最优的配置密度.[结果]生物刷对TN、NO2均有一定的去除效果,对DO的升高也有一定的作用；在此试验条件下,试验组②生物滤料净化精养池水的综合效果最佳.[结论]生物刷对精养池塘废水具有良好的净化效果,在此试验条件下,净化废水所需的最优密度配置为0.07串/L.
