Improved formula for electroplating wastewater treatment

Abstract

The invention relates to an improved formula for electroplating wastewater treatment. The formula includes, by weight percentage, 23-26 parts of calcium oxide, 3-8 parts of calcium hydroxide, 11-15 parts of activated alumina, 1-5 parts of polyacrylamide, 21-28 parts of persulfate, 0.1-0.6 part of isoascorbic acid, 6-15 parts of oxidizing agent, 0.1-0.6 part of fresh ginger extract acid, 5-8 partsof insoluble starch xanthate, 1.3-3.2 parts of sepiolite powder, 9-14 parts of active diatomaceous earth, 0.2-0.7 part of barium sulfate, 6-12 parts of basic catalyst, 0.7-1.8 parts of potassium ethoxide, 3-6 parts of polydimethylsiloxane di-quaternary ammonium salt, 1-4 parts of aluminum sulfate, and 2-4 parts of potassium borohydride. The improved formula for electroplating wastewater treatmenthas the advantages that a prepared electroplating wastewater treatment agent can effectively remove oil strains, rust, cyanide, free acid, heavy metals and the like in electroplating wastewater, is convenient to use, and can be used for auxiliary treatment of wastewater generated in various stages of electroplating.

Description

technical field [0001] The invention relates to the field of electroplating wastewater treatment, in particular to an improved formula for electroplating wastewater treatment. 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 com...

AI Technical Summary

Problems solved by technology

The chemical method has the disadvantages of low treatment efficiency, poor effluent quality, inability to recycle, and a large amount of sludge generated.

The physicochemical method has problems such as high processing cost and difficult recycling of the regeneration solution, and the application effect is not obvious

The biological method has disadvantages such as low reaction efficiency, large consumption of medium, high treatment cost, residual organisms in the effluent can continue to reproduce, and cannot be directly reused.

[0004] At the same time, the existing treatment agents for electroplating wastewater cannot effectively remove oil, rust, cyanide, free acid, heavy metals and other substances in electroplating wastewater at the same time, and the treatment effect is not good.
