Cyaniding wastewater treatment system based on ozone oxidation technology

The invention discloses a cyaniding wastewater treatment system based on ozonation technology, which belongs to the technical field of wastewater treatment, and comprises an acid-base adjusting tank, a reaction tank and an ozone generator, the acid-base adjusting tank is communicated with a first pipeline for conveying initial wastewater, and the acid-base adjusting tank is communicated with the reaction tank through a second pipeline; the second pipeline is used for conveying wastewater subjected to acid-base adjustment, the reaction tank is communicated with the ozone generator through a third pipeline, the third pipeline is used for conveying ozone, and the bottom of the reaction tank is communicated with a first liquid discharge pipe and a sediment discharge pipe. According to the invention, multiple treatments are obtained in the wastewater adding stage, the wastewater liquid level rising stage and the wastewater flowing stage in the through holes of the mixing cover, so that cyanide in the wastewater ca
