英文摘要： Herbicide was detected in many rivers and lakes because of its long-term and large-scale use. The problem of typical herbicide pollution became more and more serious, atrazine and diuron were two kinds of the typical representative herbicides. Synergistic adsorption and degradation of typical herbicide (atrazine and diuron) by high voltage discharge plasma coupled with Ti-loaded activated carbon fiber were conducted in the present project. The purpose of this project was to clarify the relationship between the characteristics of Ti-loaded activated carbon fiber and typical herbicide (atrazine and diuron) adsorption efficiency and degradation efficiency respectively, reveal the adsorption mechanism, synergistic degradation mechanism and toxicological effects of the typical herbicide (atrazine and diuron) by high voltage discharge plasma coupled with Ti-loaded activated carbon fiber, which were on the basis of the analysis of the effect of surface area, density of surface hydroxyl groups, and the surface zero potential point of Ti-loaded activated carbon fiber on the adsorption properties and degradation efficiency of the typical herbicide (atrazine and diuron).The implement of this project has important theoretical significance for clarifying the regulatory mechanism, adsorption mechanism, synergistic degradation
