Abstract

The invention relates to an electroplating wastewater treatment agent and a preparation method thereof. The treatment agent comprises the following components in parts by mass: 3-8 parts of calcium hydroxide, 1-5 parts of polyacrylamide, 2-6 parts of sodium phosphate, 0.5-3.5 parts of triethanolamine oleate soap, 2-5 parts of sulfonated coal tar, 0.3-1 part of chlorine dioxide, 1-4 parts of aluminum sulfate, 0.7-1.8 parts of potassium ethoxide, 0.2-0.7 part of barium sulfate, 1.3-3.2 parts of sodium sulfide, 0.1-0.6 part of ethylene diamine tetra(methylene phosphonic acid), and 0.1-0.6 part of isoascorbic acid. The electroplating wastewater treatment agent provided by the invention can effectively remove oil stains, iron rust, cyanides, free acids, heavy metals and other substances in electroplating wastewater, is convenient to use, is used for assisting treatment of wastewater produced at different stages of electroplating, and can make the concentration of Zn<2+>, Cr<3+> and Fe<3+> in the wastewater drop to less than 4.5 mg/L from 200 mg/L.

Description

technical field [0001] The invention relates to the technical field of water 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 wastewate...
