湿氧化(Wet Oxidation)是湿一种热液处理。用氧气作为氧化剂，对水中溶解或悬浮的成分进行的氧化。如果还使用空气，则被称为“湿式催化氧化法”（WAO）。氧化反应发生在过热水中，温度高于水正常的沸点（100 ° C），但低于临界点（374℃）。

该系统必须被控制在一定压力下，以避免水分过多蒸发。这样做是为了控制蒸发潜热(latent heat of vaporization)造成的能源消耗。这样做也是因为液态水是该氧化反应发生所需要的。根据湿氧化条件下的氧化不会发生在同样温度和压力条件的干氧化过程。

Wet oxidation is a form of hydrothermal treatment. It is the oxidation of dissolved or suspended components in water using oxygen as the oxidizer. It is referred to as "Wet Air Oxidation" (WAO) when air is used. The oxidation reactions occur in superheated water at a temperature above the normal boiling point of water (100° C), but below the critical point (374° C).

The system must be maintained under pressure to avoid excessive evaporation of water. This is done to control energy consumption due to the latent heat of vaporization. It is also done because liquid water is necessary for most of the oxidation reactions to occur. Compounds oxidize under wet oxidation conditions that would not oxidize under dry conditions at the same temperature and pressure.
