摘要
实验研究了有机磷农药氧乐果在超临界水中的氧化降解．结果表明，超临界水氧化技术能有效地降解氧乐果废水．随着反应温度的升高、压力的增大、停留时间的延长，ＣＯＤ去除率也随之提高氧乐果在超临界水中氧化降解的动力学方程为：－ｄ［ＣＯＤ］／ｄτ＝１．６０ｅｘｐ（－２．２５×１０~４／ＲＴ）［ＣＯＤ］^(0.90)［Ｏ_2］_0^(-0.38)［Ｈ_2Ｏ］_0^(0.053).
The oxidative degradation of the omethoate(organic phosphate pesticide) in supercritical water(SCW) is studied in this paper. The results show that omethoate wastewater can be degradated effectively by supercritical water oxidation(SCWO). The COD removal rate increases with the increase of temperature, pressure and residence time of the reaction. The oxidative degradation dynamic equation of omethoate in SCW is: d[COD]/dτ=1.60exp(-2.25x10^4/RT [COD]^(0.90) [O_2]_0^(-0.38)[H_2O]_0^(0.053).
