摘要: 为拓展人工湿地的实际应用范围,通过盆栽实验,利用低浓度生活污水对14种待选植物进行了筛选.实验结果显示,与无植物的空白对照相比,绝大多数待选植物的存在并没有明显提高盆栽对COD的去除能力,但却能够有效提高盆栽对污水中氮、磷的去除效果.水力停留时间为8h和24h时,植物吸收对去除氮的平均贡献率分别为44.5% 和40.0%,对去除磷的平均贡献率分别为20.9%和25.1%.故对COD的去除能力不适合作为筛选湿地植物的指标,而应以氮、磷的去除率作为筛选指标,同时还应综合考虑植物的抗逆性和观赏性.

Abstract:

In order to widen the application of constructed wetland, the experiments to screen 1 4 species of candi-date plants were caried out in pots with low-concentration domestic wastewater. Experimental results indicate that.as compared with the control without plant,most units with plants have no significant improvement in the caDabilitv of COD removal,but have significant improvement in the capability of nitrogen and phosphorus removals. Further-more,when the hydraulic retention time is 8 and 24 h0urs, the average contributions of the plant uptake to nitr0gen removal respectively reach 44.5% and 40.0%, and those for phosphorus removal respectively reach 20.9% and 25.1% .All these indicate that,instead of the capability of COD removal, the capability of nitrogen and phospho-rus removals can be used as a criterion for screening plants suitable to constructed wetland. also with the fact0rs such as the endurance of hard environment and the ornamental effect of the plant being considered.
