Abstract

The invention discloses a method and system for measuring and evaluating plant purification efficiency by using a fumigation system. By placing the plants to be tested in a closed environment containing indoor air pollutants (static fumigation) or into a closed environment with continuous and stable concentrations of indoor air pollutants (dynamic fumigation), by measuring the pollutants and plant parameters in the fumigation process, According to the corresponding calculation formula, the amount of pollutants absorbed by leaves per unit time and unit leaf area is analyzed to characterize the purification efficiency of different plants. The present invention can effectively overcome the problem of changes in measurement and evaluation results caused by differences in individual plants, adsorption of pot soil, and changes in pollutant parameters in the fumigation process when the absorption efficiency is used to evaluate the purification efficiency of plants, especially in the case of low-concentration fumigation. The flux of indoor gas pollutants absorbed is significantly lower than that of high-concentration fumigation, and the evaluation results are more reasonable and comparable.

Description

technical field [0001] The invention relates to the field of environmental technology, more specifically, to a method and system for measuring and evaluating plant purification efficiency by fumigation. Background technique [0002] Indoor plants can not only decorate the indoor space, but also purify indoor air pollution to a certain extent. It is a purification technology that meets the needs of the public. However, most of the current research focuses on screening plants with purification ability, and there are still few studies on the purification efficiency of plants for indoor air pollutants. In addition, due to the variability of plant physiological characteristics and the complexity of the purification dynamic mechanism and metabolic mechanism, there are still many defects in the research methods of plants to purify indoor air pollutants. Therefore, it is particularly important to establish a method for measuring and evaluating plant purification efficiency using a ...
