Technical Field

The technical field relates to the field of industrial water treatment and wastewater treatment, in particular to a ferrate oxidant composite spray-melting filter element.

Background

Along with the development of social economy, the high-efficiency cyclic utilization of water and the high standard requirement of wastewater discharge in industrial production lead the water treatment technology to develop towards the recovery of high-efficiency water and wastewater, the process foundation is that the water is concentrated, fresh water is recovered, and concentrated water is discharged, so another problem is caused, namely, the concentration of organic pollutants in the discharged concentrated water is increased, biological treatment cannot be carried out due to the high salt content of the concentrated water, evaporative crystallization can effectively solve the problem, but the high investment and operation cost limit the common use of the technology, other physical and chemical methods are mostly selected for treatment at present, such as strong oxidant oxidation, fenton, electrochemical fenton, photocatalysis, wet oxidation and the like, which are methods frequently selected for high-difficulty organic wastewater, but for the wastewater with the excessive organic pollution concentration (discharge standard), the above methods are uneconomical and expensive to invest in and operate.
