Organophosphorous pesticides are widely used for crop production, but their disposal causes serious environmental problems. Three commercial organophosphorous pesticides (phosalone, azinphos-methyl and methidathion) were treated by an electrolysis system using Ti/Pt as the anode and stainless steel 304 as the cathode. A number of experiments were run on a laboratory scale and the results are reported here. With the use of the above method, the achieved COD reduction was over 65%. The main energy consumption was about 5 KWhg sup(-1) COD reduction and the COD/BOD5 ratio was improved considerably after electrolysis. In conclusion, electrochemical oxidation could be used as a pretreatment method of the pesticides' detoxification.
