    Although the wet oxidation technology has high treatment efficiency, few secondary pollution, fast oxidation rate, and can recover energy and useful materials, it still has certain limitations in practical application
    .

    ①Wet oxidation is generally required to be carried out under high temperature and high pressure conditions, and the intermediate product is often organic acid, so the requirements for equipment materials are high, high temperature, high pressure, and corrosion resistance are required, so the equipment cost is large, and the system is one-time investment high

    ②As the wet oxidation reaction needs to be carried out under high temperature and high pressure conditions, it is only suitable for small flow and high concentration wastewater treatment
    .


    For low-concentration and large-volume wastewater, it is very uneconomical


    ③Even at very high temperatures, the removal effect of certain organic substances such as polychlorinated biphenyls and small molecular carboxylic acids is not ideal and it is difficult to achieve complete oxidation


    ④ During the wet oxidation process, more toxic intermediate products may be produced


    Although catalytic wet oxidation and supercritical water oxidation can overcome the above shortcomings to a certain extent, it is necessary to further study the mechanism, influencing factors, reaction kinetics and reactor system of wet oxidation technology in order to develop low cost and energy consumption.


    Table 3-3 lists the comparison results of supercritical water oxidation and wet air oxidation (WAO) and traditional incineration.
