吸毒草吸毒效果评价

Evaluation on the Narcotic Effect of Drug Taking Grass

目的通过吸毒草吸毒效果的评价,研究绿色植物对装修后室内污染气体的净化程度,为科学指导清除装修污染提供依据。方法分别在两个密封试验测试舱(实验舱和对照舱)内发生不同种类和浓度的气体污染物,测定不同时间内浓度的变化,计算净化效率。结果吸毒草对甲醛、总挥发性有机物和一氧化碳均有净化作用,且随着时间的增加,净化效率也逐渐增加。结论吸毒草对甲醛有较强的吸收作用;对总挥发性有机物吸收作用明显;对一氧化碳有一定的吸收作用;在有毒有害气体环境中吸毒草生长良好。

Objectives To evaluate the narcotic effect of drug taking grass,research of purifing degree on indoor pollution gas by green plants during and after the renovations,provide the evidence for scientific guidance on removing decoration pollutants.Methods Respectively in two sealed test tank(lab and contrast tank)different types and concentrations of gas pollutants were generated.The concentrations in different time were changed,purification efficiencies were calculated.Results The clearance rate of formaldehyde after 3 h by drug taking grass was 92.4%,the total volatile organic compound removal rate is 13.6%,the carbon monoxide removal rate was 20.1%;the clearance rate of formaldehyde after 24 h by drug taking grass was 96.5%,the total volatile organic compound removal rate is 74.5%,the carbon monoxide removal rate was 66.1%;the clearance rate of formaldehyde after 48 h by drug taking grass was 97.2%,the total volatile organic compound removal rate is 87.4%,the carbon monoxide removal rate was 67.4%;the clearance rate of formaldehyde after 72 h by drug taking grass was 98.5%,the total volatile organic compound removal rate is 84.8%,the removal rate of 71.3% was for carbon monoxide.Conclusions The drug taking grass on formaldehyde has strong absorption function;the absorption is obvious for the total volatile organic compounds;there is certain absorption effect for carbon monoxide;drug taking grass is growing up better within polluted air.
