| titleOfInvention | A kind of processing method of metal plating waste water |
| abstract | The embodiment of the invention discloses the processing method of a kind of metal plating waste water, comprise the following steps: nickel-containing waste water pretreatment；Chromate waste water pretreatment；Use the mode identical with nickel-containing waste water preconditioned pattern to copper-containing wastewater pretreatment；Cyanide wastewater pretreatment；Composite waste of electrolytic plating processes: composite waste of electrolytic plating includes produced pre-treatment waste water in manufacture process, cleans waste water, electroplating wastewater etc., also include nickel-containing waste water after pretreatment, chromate waste water, copper-containing wastewater, cyanide wastewater simultaneously, this four classes waste water drains into comprehensive wastewater collecting pit in the lump with other pre-treatment waste water, cleaning waste water etc. after pretreatment, arranges stirring system in comprehensive collection pond；Finally carry out integrative electroplating waste process.The present invention carries out chemical reaction nonhazardous process for heavy metal and severe toxicity cyanide, it is achieved one-stop circulation electroplating wastewater processing, improves the treatment effeciency of metal plating waste water, decreases water and pollutes. |
