Abstract

The invention relates to a method for representing a 17beta-estradiol (E2) soil column leaching process, and belongs to the field of environmental science and environmental engineering subject. The method includes steps of 1), filling soil samples into a soil column apparatus uniformly, leaching after uniformly adding E2 standard samples on the surface layer of a soil column, and measuring concentrations of E2 and E1 in leachate and calculating accumulative leaching quantity; 2), setting size and boundary of cell sets and initializing cell status; 3), making an evolution rule according to a micromechanism; 4) calculating parameters required for a model; and 5), performing iterative calculation. By the method, advantages of flexibility and diversity of a CA (cellular automata) model are utilized, and the CA model capable of simulating the E2 soil column leaching process is established according to the micromechanism that the E2 is subjected to adsorption, desorption, degradation and migration in the soil column leaching process, so that dynamically visual representation of the E2 in the soil column leaching process is achieved.

Description

technical field

[0001] The present invention relates to a technique for reproducing the migration and transformation of pollutants in the soil column leaching process, in particular to a method for reproducing the 17β-estradiol (E2) soil column leaching process based on a cellular automata model. The method can provide important technical guidance for predicting and controlling the migration and transformation of E2 in soil, and belongs to the field of environmental science and environmental engineering. Background technique

[0002] In recent years, natural estrogens such as estrone (E1) and 17β-estradiol (E2) have received extensive attention as typical environmental endocrine disruptors. Then migrate and transform in the environment. At present, technical research on simulating and controlling the migration and transformation of organic pollutants in soil has become the focus. The soil column leaching experiment under laboratory conditions is an important means to study...
