This paper presents the mechanism research on the decontamination of air pollution by plants in recent years,mainly including the following: absorption and sorption of stoma and cuticle on leaf surface,plant metabolism and enzyme redox,and degradation by plant in combination with bacteria in root.
介绍了植物去除空气污染物的研究现状及机理,主要包括:通过叶表面的气孔和表皮吸收、吸附;植物体内代谢或者分泌酶催化氧化还原进入体内的污染物;通过植物联合根系微生物降解由于干湿沉降进入土壤或者水体中的污染物等。
The process bases on the adsorption/absorption capability of microorg.
本文探讨了城市污水资源化生物净化工艺的新途径,即首先通过生物吸附/吸收作用将污水有机物、氮、磷从水中转移到污泥中,达到污水净化的目的;再使污泥将污染物释放出来,把有机物转化为甲烷,把氮、磷沉淀后回收,污泥经活化后再次用于吸附。
Through systematical comparison about the different oil vapor recovery schemes based on adsorption,it was concluded that the combined adsorption/absorption scheme is nowadays the most popular technology all over the world for large-scale oil delivery application.
通过对基于吸附法的油气回收工艺流程进行系统对比分析,揭示了吸附/吸收组合工艺是目前世界范围内油品大周转量场合的主流技术方案,吸附/冷凝组合、吸收/膜/吸附组合等变型工艺仅在某些特定场合才得以使用。
