Abstract

The invention relates to sewage treatment equipment using expanded anode for electrolytically decomposing cyanide, which comprises a shell, a cathode plate, an anode plate, a particle electrode filled between the cathode plate and the anode plate, a direct current power supply connected with the cathode plate and the anode plate, a water inlet groove, a water inlet, a water outlet, a water outlet groove, a drain pipe, an aerator pipe and a mud hole. The sewage treatment equipment is improved in the following aspects: the cathode plate and the anode plate are vertically and oppositely fixed in the shell in parallel; an insulating layer is adhered to the surface of the cathode plate; and the particle electrode is made of the same material as the anode plate and together with the anode plate forms an expanded anode. The equipment is divided into a plurality of independent reaction chambers by polar plates in the equipment; the waste water is uniformly distributed by the water inlet groove, flows upwards from the lower water inlets of the reaction chambers to pass through the reactors and flows out from the upper water outlets to converge into the water outlet groove. Each reaction chamber is filled with the particles of a material the same as the anode material, so the anode area is expanded and the mass transfer effect and the reaction efficiency are improved. Thus, the cyanide in the waste water is degraded efficiently.

Description

technical field [0001] The invention relates to a device for treating high-concentration cyanide-containing wastewater by means of electrochemical electrolysis and catalysis, and belongs to the technical field of electrochemical wastewater treatment. Background technique [0002] Cyanide is a highly toxic and harmful chemical. Its effects on humans and warm-blooded animals are: high toxicity and fast reaction, especially when the mass concentration of hydrogen cyanide gas reaches 0.005mg / L , it will cause symptoms such as headache and arrhythmia in a short period of time. When it reaches a moderate concentration, in most cases, it will die within 1 hour, and a few will die within 24 hours. [0003] Cyanide is widely used in various fields of the national economy, and it is easy to produce a large amount of toxic cyanide-containing wastewater during use, especially in the production processes of pesticides, pharmaceuticals, fine chemicals, gold refining, surface treatment and...
