Wastewater containing unsymmetrical dimethylhydrazine was treated with oxidation method of chlorine dioxide,and the chemical reaction mechanism was determined through data analysis. The wastewater was treated with multistage oxidation column and activated carbon adsorption column. Results showed that mole ratio of unsymmetrical dimethylhydrazine to chlorine dioxide was controlled between 1 : 9 and 1:11, and multistage oxidation column series were used to enhance oxidization efficiency and utilization of chlorine dioxide. Under the conditions of mole ratio of unsymmetrical dimethylhydrazine to chlorine dioxide 1:9, oxidation temperature 15t, assembly time 15d, flow rate of wastewater through φ25×400 adsorption column (100g activated carbon) was 3mL/min. The treated wastewater can satisfy GB8978-1996standard for wastewater discharge.
