Problems solved by technology

The performance of the three-dimensional particle electrode determines the processing efficiency of the three-dimensional electrolysis. At present, there is a short-flow phenomenon in the application (because the particle electrodes are too close and the entire electrode is in a static state, the particle electrode filled between the anode and the cathode The overall resistance is too small, resulting in ver

Embodiment Construction

[0052] 1. Cyanide removal particle electrode

[0053] The invention provides a new cyanide-removing particle electrode capable of effectively removing cyanide ions in industrial wastewater with a cyanide ion concentration of 2000-3000 mg / L (high-concentration cyanide-containing wastewater in the industry).

[0054] The particle electrode for removing cyanide is composed of foam metal, metal salt and binder.

[0055] The foamed metal is used as the substrate of the particle electrode for removing cyanide, and there are many three-dimensional network holes evenly distributed thereon. The metal salt is used as a catalyst, and the binder uniformly consolidates the metal salt on the surface of the foam metal and the inner surface of the three-dimensional network holes.

[0056] The metal foam can be nickel foam, copper foam or titanium foam. These metal foams not only have numerous three-dimensional network holes, but also can be produced according to the size of the three-dimensiona

Abstract

The invention relates to a cyanide particle removal electrode suitable for treating high-concentration cyanide-containing wastewater and removing cyanide completely and a preparation method and a method and apparatus for treating high-concentration cyanide-containing wastewater. The cyanide particle removal electrode consists of a foam metal, a metal salt and a binder. The method for treating high-concentration cyanide-containing wastewater can perform cyanide breaking treatment on cyanide-containing wastewater with a cyanide ion concentration of 2000-3000 mg/L. The treatment apparatus comprises an ozone-three-dimensional electrolysis main reactor. The main reactor can treat the high-concentration cyanide-containing wastewater to reach the standard in a short period of time. The cyanide particle removal electrode has excellent electrochemical performance, the preparation method is simple and can be mass-produced, a space utilization rate is high, the cyanide particle removal electrodeis filled between cathode and anode plates of conventional two-dimensional electrolysis to form a third electrode, and thereby the cyanide ion removal apparatus with light weight, small land occupation area, high efficiency and low energy consumption is constructed.
