Abstract

The invention discloses an electroplating wastewater treatment agent, consisting of a reducing agent, a composite flocculant, a heavy metal ion collector DTCR, starch xanthate, cross-linked rectorite, quaternary ammonium salt lignin, sodium silicate, an alkaline substance and an adsorption filler. According to the treatment agent, the materials realize a synergistic effect, multiple heavy metal ions can be effectively removed, heavy metal ions with multiple ions coexisting also can be effectively removed, the treatment effect on electroplating wastewater is excellent, the performance is stable, the sedimentation effect is good, and the sedimentation speed is high; besides, the electroplating wastewater treatment agent is reasonable in ratio, non-poisonous and free of environment pollution.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an electroplating wastewater treatment agent. Background technique [0002] The sources of electroplating wastewater include cleaning water for plating parts, waste electroplating solution and other wastewater. The quality and quantity of electroplating wastewater are related to the process conditions, production load, operation management and water use methods of electroplating production. The water quality of electroplating wastewater is complex, and its composition is not easy to control. It contains heavy metal ions such as chromium, nickel, copper, zinc, gold, silver and cyanide, etc., and the composition of wastewater is complex. [0003] At present, there are many comprehensive wastewater treatment methods used in electroplating wastewater, such as chemical method, ion exchange method, electrodialysis method, electrolysis method, etc. Among them, chemical method i...
