Problems solved by technology

The cyanide-copper-containing wastewater after copper electroplating mainly adopts the two-stage cyanide breaking method of the alkaline chlorination method, but this method directly uses the two-stage cyanide breaking method of the alkaline chlorination method, and the consumption of sodium hypochlorite or calcium hypochlorite is relatively large. High operating costs for cyanide-containing wastewater treatment
Not suitable for large-scale industrialization

Abstract

The invention discloses a recycling treatment device for wastewater containing copper cyanide. The recycling treatment device comprises a pretreatment system for wastewater containing copper cyanide , a first-stage membrane separation treatment system, a second-stage membrane separation treatment system and a conveying system which communicate with one another sequentially through a pipeline; and the pretreatment system for wastewater containing copper cyanide comprises a collection tank for wastewater containing copper cyanide, a raw water pump, a filter, a carbon filter, a pretreatment fine filter, an ultrafilter, a backwashing pump and a pretreatment water tank which communicate with one another sequentially through a pipeline, the first-stage membrane separation treatment system comprises a first-stage boosting pump, a first-stage fine filter, a first-stage high-pressure pump, a first-stage membrane separation device and a first-stage intermediate water tank which communicate with one another sequentially through a pipeline, the second-stage membrane separation treatment system comprises a second-stage boosting pump, a second-stage high-pressure pump and a second-stage membrane separation device which communicate with one another sequentially through a pipeline, and the conveying system comprises a recycling water tank and a conveying pump which communicate with each other sequentially through a pipeline. The recycling treatment device has the advantages that the cost is reduced, and the arrangement is reasonable.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a recycling treatment device for cyanide-copper-containing wastewater. Background technique [0002] Cyanide is widely used as the best complexing agent in electroplating. Cyanide has a very high complexing ability, and can form complexes with zinc, cadmium, copper, silver, gold, etc. The cyanide electroplating solution composed of cyanide complexes has excellent performance. However, cyanide is highly toxic, and cyanide-containing wastewater mainly comes from industries such as electroplating or wet gold extraction. The cyanide-copper-containing wastewater after copper electroplating mainly adopts the two-stage cyanide breaking method of the alkaline chlorination method, but this method of directly using the alkaline chlorination method for two-stage cyanide breaking method requires a relatively large amount of sodium hypochlorite or calcium hypochlorite. The operating cost...
