以6组90 d龄期的组合骨料型百喜草植生混凝土盆栽为研究对象,用配制溶液静态培养的方法,选择氨氮(NH_3-N)、总氮(TN)和总磷(TP)为主要指标,考查沸石与钢渣、沸石与浮石两种组合骨料型的植生混凝土对污染物的去除效果。结果表明,各组NH_3-N 1 d、7 d的去除率分别为13.0% ~16.9%和45.7% ~56.7%,1 d去除率约占7 d的30%。各组TN 1 d、7 d的去除率分别为9.0% ~14.1%和25.6% ~39.2%,1 d去除率约占7 d的30%。各组TP 1 d、7 d的去除率分别为22.0% ~ 33.3%和57.3% ~89.3%,1 d去除率约占7 d的40%。NO_3~--N、NO_2~- -N含量很低,NO_3~- -N浓度基本在0.50 mg/L以下,NO_2~- -N浓度变化范围在0.10 mg/L以下。综...

An experiment was conducted on six groups of composited aggregate planting concrete, in which Paspalum Notatum Flugge (Bahia Grass) was vegetated in pots for 90 days. The impact of composited aggregate zeolite-steel slag and zeolite-pumice on the efficacy of removal of contaminants based on NH3-N, TN, and TP was investigated under static cultivation conditions. The results showed that the removal rate of NH3-N was from 13.0% to 16.9% after 1 d, approximately 30% of that after 7 d (from 45.7% to 56.7%). The removal rate of TN was from 9.0% to 14...
