摘要
Abstract
Treatment of DDVP production wastewater was conducted using mixed oxidants of hydrogen peroxide and sodium persulfate,catalyzed by cobalt tetrakis (4-sulfonatophenyl) porphyrin(CoTPPS4) .Influencing factors on catalytic activities for treatment of DDVP production wastewater were discussed,such as oxidant species ,mixing ratio between oxidants,amount of additional catalyst,initial concentration of pesticide and pH value. Reaction kinetics of degradation reaction was also studied. The results indicated that the COD removal efficiency of 28.93 mg/L DDVP can reach to 99.65％ after 25 h,while additional volume of Na2S2O8 and H2O2 (4/1,v/v) is 5 mL,catalyst dosage is 2.4 × 10-3 g at pH =9. Reaction kinetics studies suggest the catalyzed oxidative treament of DDVP production wastewater is pseudo-first-order reaction and activation energy Ea=5.0524 kJ/mol.关键词
