TREATMENT DEVICE AND TREATMENT METHOD FOR ORGANIC PHOSPHOROUS BASED PESTICIDE-CONTAINING WATER

PROBLEM TO BE SOLVED: To provide a treatment device and a treatment method for organic phosphorous based pesticide-containing water where, first, OH radicals are efficiently produced, thus an organic phosphorous based pesticide can be securely oxidized and decomposed, and secondary, the above operations can be achieved under excellent running cost, posttreatment cost, easiness of control, stability of treatment, initial cost or the like. SOLUTION: In the treatment device 2 and the treatment method, an organic phosphorous based pesticide 1 comprised in treatment water 3 is oxidized and decomposed based on a Fenton process. Then, the treatment device 2 is provided with: a treatment tank 4; and a treatment water feeding means 5, a hydrogen peroxide adding means 6, an iron ion adding means 7 and a pH regulating means 8 attached to the treatment tank 4. Regarding the hydrogen peroxide adding means 6, hydrogen peroxide is added to the treatment water 3 in the treatment tank 4, regarding the iron ion adding means 7, bivalent ion ions are added to the treatment water 3, and, regarding the pH regulating means 8, a pH regulator is added to the treatment water 3, and the treatment water 3 is retained to prescribed weak acidity.
