  • 摘要: 采用动态模拟法模拟盆栽植物对甲苯污染气体的净化,考察吊兰和金绿萝两种盆栽植物在净化甲苯过程中,甲苯入口浓度与植物对甲苯净化速率的关系。结果表明,2种盆栽植物对低浓度甲苯废气具有长期明显的净化效果。在相同条件下,吊兰茎叶和土壤的净化速率优于金绿萝体系。在植物的耐受浓度范围内,2种植物茎叶和土壤的净化速率均随着甲苯入口浓度的升高而增大,且白天的净化速率明显高于黑夜时的净化速率。在实验过程中,吊兰土壤体系的降解率随着甲苯浓度的升高逐渐下降;金绿萝土壤体系的降解率基本不受甲苯入口浓度的影响。吊兰盆栽体系的降解率明显大于金绿萝的降解率。两种植物盆栽体系的降解率随甲苯进口浓度的影响可以忽略。
    Abstract: A dynamic method was used to simulate the toluene purification by the potted plant for investigating the relation between toluene concentration and removal capacities for potted spider plant and golden pothos. The results showed that the two kinds of plants can obviously remove toluene from air in a long time. The toluene removal capacities for shoots and soil of the spider plant were respectively higher than for golden pothos in the same environment. The removal capacities for shoots and soil of a couple of plants increased with inlet toluene concentration. The removal capacities were higher in the daytime than in the nighttime. The degradation efficiency of soil of spider plant decreased while that of golden pothos did not drop with enhancing toluene concentration. The potted spider plant had higher degradation efficiency compared with golden pothos. The effect of inlet toluene concentration on degradation efficiencies of the potted plants can be negligible.
