2021-12-17
The practical new type belongs to the field of cyanide wastewater process device technology, and specifically refers to a set of device for cyanide wastewater electrolysis in filling bed. In it, the pH adjustment raw water buffing tank has in-built agitator, which is equipped with raw water inlet, raw water outlet, pH adjustment reagent feeding end and front pH detector; the pH modifier container is connected to pH modifier feeding end via pH modifier metering pump, the raw water outlet of pH adjustment raw water buffing tank is connected to electrolysis water inlet of the filling bed electrolysis reactor via liquid inlet pump, the electrolysis water outlet of the filling bed electrolysis reactor is connected to the flocculant water inlet in the precipitation pool via pipeline mixer, and the precipitation pool has clear water overflow exit at the side walls and precipitate discharge at the bottom, the flocculant allocation tank is connected to pipeline mixer via flocculant metering pump; the pH of cyanide wastewater is adjusted prior to breaking cyanide under certain intensity of current, then the gold, silver and copper on the cathode plate are recovered, at the same time the purified wastewater is recycled to the process.
