| Abstract: | Based on the oxidative mechanism of unsymmetrical dimethylhydrazine with ClO_2,the depth of the oxidation.the efficiency and utilization rate of oxidant and simulation test of wastewater treatment were investigated detailly.The results showed that the optinum treament processes of wastewater containing unsymmetrical dimethylhydrazine was established as follow:The molar ratio of unsymmetrical dimethylhydrazine to ClO_2 was 1:9,series multistage contact oxidation process was used,oxidation temperature was 15 ℃,aging time Was 15 days.Physical and chemical indexes of treated wastewater meet the discharge standard requirements of GB8978-1996 after the wastewater was treated by adsorption column(25 mm × 400 mm,100 g active carbon)with 3 mL/min flow rate. |
