吊兰和常春藤对室内甲醛污染降解能力的研究

Study on Degradation Abilities of Chlorophytum comosum and Hedera nepalensis on Indoor Formaldehyde Pollution

[目的]研究吊兰和常春藤对室内甲醛污染的降解能力。[方法]通过实验室模拟室内甲醛污染环境,选用吊兰和常春藤盆栽植物进行去除甲醛的试验研究。[结果]吊兰和常春藤均具有不同程度净化甲醛的能力。吊兰和常春藤同时配置效果明显优于吊兰,而吊兰对甲醛的降解要强于常春藤。从东南到西北不同水平配置和由下层到上、中层的不同垂直配置的植物叶片叶绿素含量均呈上升趋势。[结论]盆栽植物的筛选和优化组合配置可为有效防治室内长期污染、真正改善室内环境质量提供科学依据。

[Objective] The research aimed to study on degradation abilities of Chlorophytum comosum and Hedera nepalensis on indoor formaldehyde pollution.[Method] By simulating indoor formaldehyde pollution environment in laboratory,Chlorophytum comosum and Hedera nepalensis were selected to conduct test on formaldehyde removal.[Result] Both Chlorophytum comosum and Hedera nepalensis had different purifying abilities on formaldehyde.Configuration effect of Chlorophytum comosum and Hedera nepalensis was significantly better than Chlorophytum comosum.Degradation ability of Chlorophytum comosum on formaldehyde was stronger than Hedera nepalensis.At horizontal configuration from southeast to northwest and vertical configuration from lower layer to upper and middle layers,chlorophyll content all presented rise tendency.[Conclusion] Screening and optimal configuration of the potted plants could provide scientific basis for effectively preventing and controlling indoor long-term pollution and really improving indoor environmental quality.
