试验研究了水力停留时间（HRT）及浮床覆盖率对分别种植了空心菜和香根草的生态浮床系统处理再生水效果的影响。结果表明：①HRT对TN，TP去除效果影响较大，对CODCr，NH3-N的去除效果影响较小，2种浮床系统随HRT的增加其水质净化效果逐渐提高。综合考虑，HRT应保持在3 d左右；②随覆盖率的增加，2种浮床系统处理效果的变化趋势基本一致，其中对TN，TP的去除效果影响显著。综合分析，2种浮床系统比较理想的浮床覆盖率为45%左右。
試驗研究瞭水力停留時間（HRT）及浮床覆蓋率對分彆種植瞭空心菜和香根草的生態浮床繫統處理再生水效果的影響。結果錶明：①HRT對TN，TP去除效果影響較大，對CODCr，NH3-N的去除效果影響較小，2種浮床繫統隨HRT的增加其水質淨化效果逐漸提高。綜閤攷慮，HRT應保持在3 d左右；②隨覆蓋率的增加，2種浮床繫統處理效果的變化趨勢基本一緻，其中對TN，TP的去除效果影響顯著。綜閤分析，2種浮床繫統比較理想的浮床覆蓋率為45%左右。

The effects of hydraulic retention time (HRT) and coverage ratio of Ipomoea Aquatica Forsk floating bed and Vetiveria zizanioides floating bed for reclaimed water treatment were studied. The results showed that: ① Effect of HRT on the removal of TN and TP were larger than that of CODCr and NH3-N. Two systems purification effect gradually improved with the increase of HRT. Taken together, HRT should be kept about 3d; ② The change tendency of treatment efficiency were almost the same as the increase of coverage, and coverage ratios has significant influences on the removal of TN and TP. Ideal coverage ratios should be about 45%.
