Electroplating wastewater treating agent and preparation method thereof

Abstract

The invention discloses an electroplating wastewater treatment agent and a preparation method thereof. The electroplating wastewater treatment agent is prepared from, by mass, 3-5 parts of reducing agent, 6-10 parts of bentonite, 6-8 parts of graphene nanolayer, 3-5 parts of amino trimethylene phosphonic acid, 1-2 parts of heavy metal ion trapping agent, 4-6 parts of poly-ferric sulfate, 6-8 parts of modified sulfonated lignin, 6-10 parts of sodium polyacrylate, 1-3 parts of compound coagulant, 4-6 parts of benzotriazole, 6-8 parts of starch xanthate, 5-7 parts of trithione triazine trisodium salt and 4-6 parts of crosslinked rectorite. The preparation method is simple, heavy metal ions can be removed only by putting the agent, no device nor process is added, and the cost for treating electroplating wastewater is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an electroplating wastewater treatment agent and a preparation method thereof. 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 wastewat...

AI Technical Summary

Problems solved by technology

The water quality of electroplating wastewater is complex, and its composition is difficult to control. It contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, silver, and cyanide, and some are highly toxic substances that are carcinogenic, teratogenic, and mutagenic.
