| 摘 要： | 研究实际地下水硫自养反硝化动力学过程，考察季节因素(温度)对动力学的影响，实验结果表明，地下水升流式硫自养滤柱反硝化动力学符合1/2级动力学模型，其反应速率常数受温度的影响很大，用阿仑尼乌斯方程计算硫自养反硝化活化能为80.38 kJ/mol。硫自养反硝化产生的硫酸根与反硝化掉的硝酸根离子呈线性相关。在地下水不经任何预处理的条件下，硫自养反硝化仍能有效地脱除地下水中的硝酸盐，反应器出水的pH值仍维持在中性范围。

| Abstract: | The kinetics process and temperature impact of natural groundwater denitrified by sulfur autotrophic was investigated. The results revealed that the denitrification rate of up-flow sulfur autotrophic denitrification filter followed a half-order kinetics model; and the reaction rate constant was mainly affected by the temperature. Based on the Arrhenius calculation, the activated energy was 80.38 kJ/mol. The concentration of generated sulfate during this denitrification process was linearly related to the concentration of reduced nitrate. Without any pretreatment process, the reactor could remove nitrate efficiently from groundwater, and the pH of effluent kept neutralization. |
