Abstract
The present disclosure relates to the field of resource-oriented utilization technologies for wastewater salt muds and more particular to a resource-oriented utilization method for a high-salt salt mud containing sodium chloride and sodium sulfate. The method includes: performing two stages of oxidation, i.e. Fenton-like treatment and chlorine dioxide treatment, in sequence on a salt mud solution, and then replacing a sodium salt with an ammonium salt to prepare a pure alkali and a mixed ammonium salt. In the method, multi-stage oxidation process is performed to effectively use ingredients such as sodium chloride and sodium sulfate so as to thoroughly eliminate organic matters and heavy metals in the high-salt salt mud, and achieve resource-oriented utilization of the salt mud, thus saving burial treatment costs, and producing good economic benefits as well as good environmental benefits.
