Expansion of anode electrolysis cyanide breaking wastewater treatment equipment

Abstract

The invention relates to an extended anode electrolysis cyanide-breaking wastewater treatment equipment, which consists of: a shell, a cathode plate, an anode plate, a particle electrode filled between the cathode and anode plates, a DC power supply connected to the cathode and anode plates, and a water inlet tank, an inlet Water holes, water outlet holes, water outlet tanks, drain pipes, aeration pipes, and mud discharge outlets are improved in that: the cathode plate and the anode plate are vertically and parallelly fixed in the housing, and the surface of the cathode plate is attached with an insulating In the isolation layer, the material of the particle electrode is the same as that of the anode plate, and together with the anode plate, an extended anode is formed. The internal plate of the equipment isolates several independent reaction chambers. After the waste water is evenly distributed through the water inlet tank, it flows upward through the reactor from the lower water inlet hole of each reaction chamber, flows out from the upper water outlet hole, and collects into the water outlet tank. Since each reaction chamber is filled with particles consistent with the anode material, the area of ​​the anode is expanded, the mass transfer effect and reaction efficiency are improved, and the cyanide in the wastewater can be efficiently degraded and treated.

Description

Technical field

[0001] The invention relates to a device for treating high-concentration cyanide-containing wastewater by an electrochemical electrolysis catalytic method, and belongs to the technical field of electrochemical wastewater treatment. Background technique

[0002] Cyanide is a highly toxic and hazardous chemical. Its effects on humans and warm-blooded animals are: high toxicity and fast response, especially when the mass concentration of hydrogen cyanide gas reaches 0.005mg / L , It will cause 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. A large amount of toxic cyanide-containing wastewater is easily generated during use, especially in the production processes of pesticides, pharmaceuticals, fine chemicals, gold extraction, surface treatment and other industries.
