Abstract

The invention belongs to the technical field of sewage treating agents and particularly relates to a treating agent for electroplating waste water. The treating agent for electroplating waste water comprises the following raw materials by weight: 20-30 parts of reducing agent, 5-8 parts of amino trimethylene phosphonic acid, 10-20 parts of sodium polyacrylate, 10-15 parts of heavy metal ion collector, 10-20 parts of starch xanthate, 2-5 parts of GNS (Graphene Nanosheet) / MnO2 composite, 20-30 parts of crosslinking rectorite, 6-8 parts of 1, 3, 5-triazine-2, 4, 6 trithiol trisodium salt, 10-20 parts of quaternary ammonium salt lignin flocculant and 30-40 parts of coal ash. The treating agent for electroplating waste water, which is compounded by the raw materials, performs a synergistic function and can capture various metal ions in water. The treatment method is simple. As long as the chemical agent is thrown in the electroplating waste water, heavy metal ions can be removed. No equipment or technologies are increased, so that the treatment cost of the electroplating waste water is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an electroplating wastewater treatment agent. Background technique [0002] The sources of electroplating wastewater are generally: (1) plating cleaning water; (2) waste electroplating solution; (3) other wastewater, including washing the floor of the workshop, scrubbing plate washing water, condensed water from ventilation equipment, and leakage from plating tanks. Or various tank liquids and drainages of "running, popping, dripping, and leaking" caused by improper operation and management; (4) Equipment cooling water, which has not been polluted except for the temperature rise during use. The water quality and quantity of electroplating wastewater are related to the process conditions of electroplating production, production load, operation management and water use methods and other factors. The water quality of electroplating wastewater is complex and its composition...
