%X 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.
