摘　　要：采用以沸石和煤渣为基质的复合生态床修复北方微污染景观水体,考察了水力停留时间、温度、植物等因素对修复效果的影响。结果表明,当水力停留时间由1h增至4h时,系统对NH4+-N和TP的去除率分别由91.5%、31.8%提高至98%、52.5%;当温度下降时,对NH4+-N的总体去除效果无明显变化,对TP的去除率则明显降低;在床体表面种植植物能够提高系统对NH4+-N、TP和TOC的去除效果。The compound ecological filter bed with zeolite and coal cinder as media was applied to remedy the northern landscape water. The effects of hydraulic retention time （ HRT）, temperature and plants on remediation efficiency were investigated. The results show that when HRT increases from 1 h to 4 h, the removal rates of NH4＋ - N and TP increase from 91.5% and 31.8% to 98% and 52.5% re- spectively. With the temperature decreasing, the removal efficiency of NH4＋ - N has no significant change, while the removal rate of TP decreases significantly. Planting on the compound ecological filter bed can improve the removal efficiencies of NH4＋ - N, TP and TOC.
