Abstract

Oxidation of organic phosphorus pesticides wastewater (OPPs-MW) was studied in a batch-reactor under the supercritical oxidizing water condition. The temperature, pressure and coefficient of oxidation were investigated as influence factor for COD removal efficiency by response surface methodology. Temperature is the most significant factor in treatment OPPs-MW and a good fitting polynomial equation obtained. Organic acid would generate under incomplete decomposition condition and NH3-N could hardly decompose effectively when temperature below 600°C.
