| 中文摘要 |
| 在湿式空气氧化法和Fenton试剂的基础上,研究了一种新的低压湿式催化氧化法。该法与湿式空气氧化法相比,压力为0.1-0.6MPa,而后者压力为3.5-10MPa;温度小于180℃;与Fenton法相比,当H2O2·COD(重量比)小于1.2时,对COD大于14000mg/L的含酚废水,COD去除率提高20%以上,试验证实硫酸在加温、加压(0.1-0.6MPa,104-165℃)条件下对Fenton试剂除COD具有协同作用。用该法还进行了部分染料和农药废水处理研究。 |
| 英文摘要 |
| Based on catalytic wet air oxidation and Fenton reagent,a new wet catalytic oxidation(LPWCO)method,which requires low pressure for the treatment of high concentration and refractory organic wastewater was studied. The method compared with general catalytic wet air oxidation,the pressure of the treatment is 0.1-0.6MPa,and the latter is 3 5-10MPa. In addition,its temperature is no more than 180℃. The removal of COD by the treatment is over twenty percents more than Fenton's,while,H2O2:COD(weight ratio)less than one point two at the condition of phenol influent content more than 14000mg/L of COD. The existence of synergistic effect for COD removal in H2SO4+Fenton system under the condition of added pressure and heating(0.1-0.6MPa,104-165℃)was verified.It was carried out that five kinds of dye and pesticide wastewater was treated using the method. |
