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Ｈ２Ｏ２ＣＯＤ（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．
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,H 2O 2∶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 H 2SO 4+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.
