A great deal of saponification liquid, which is a kind of organic wastewater to be difficult in treatment because of mass hurt matter, is produced during the production of cyclohexanone by the oxidation of cycheloxane. Some petrochemical factory treats saponification liquid by the method of incineration on the basis of using for reference the technique of black liquor, which is used in the paper mill industry. A kind of byproduct (vapour) is gained and the sodium carbonate is reclaimed. The method has good social,environmental and economic benefits because it can achieve the innocent treatment and resource reuse of saponification liquid. The profit of 100～200 yuan is gained when a ton of saponification liquid is treated.
