颗粒物与天然水体痕量有机物相互作用的动态模型

A Dynamic Model on the Interaction between Water Particles and Trace Organic Chemicals

摘要: 在颗粒物对水中邻苯二甲酸酯吸附、水解、生物降解和藻类富集实验的基础上,提出了颗粒物与天然水体中痕量有机物相互作用的动态数学模型.用该模型研究了邻苯二甲酸二甲酯和邻苯二甲酸二辛酯在水库中的各相浓度分布.结果表明,大多数的污染物存在于藻体和颗粒物上.

Abstract: A dynamic model on interaction between water particles and trace organis chemicals was presented on the basis of the research of adsorption,hydrolysis,biodegradation and algae accumulation in water.The concentration distribution of dimethlyl phthalate and dioctyl phthalate in aquatic environment was calculated by using the model.The results show that the concentration of phthalate esters in algae and particles in higher than those in water.
