Environment-friendly treatment system and treatment method for electroplating wastewater

Abstract

The invention relates to the technical field of electroplating wastewater treatment, and in particular, relates to an environment-friendly treatment system and treatment method for electroplating wastewater. The environment-friendly treatment system for the electroplating wastewater comprises a bottom rack, a supporting frame, a standing box, a pretreatment mechanism, a retreatment mechanism and a collection frame. The environment-friendly treatment system for the electroplating wastewater provided by the invention can solve the problems that floating impurities exist in electroplating wastewater, blockage is easy to occur in the filtering process and the like; cleaning claws designed to be in a hook shape can collect and pretreat floating impurities in the electroplating wastewater, and it is ensured that the floating impurities cannot affect follow-up impurity removal and disinfection treatment of the electroplating wastewater; in cleaning branch chains disclosed by the invention, scraping plates can scrape the impurities on a metal filter screen through mutual cooperation of connecting spring rods and scraping frames, it is ensured that the impurities cannot block meshes in the metal filter screen, and the electroplating wastewater filtering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electroplating wastewater treatment, in particular to an electroplating wastewater environmental protection treatment system and treatment method. Background technique [0002] Electroplating wastewater is a kind of industrial wastewater, which usually includes plating cleaning water, waste electroplating solution, plate cleaning water, equipment condensation water and aqueduct leakage, etc. The water quality and quantity of electroplating wastewater are related to the process conditions of electroplating production, production load, Operation management is related to factors such as water use methods. Due to the complex water quality of electroplating wastewater, the composition is not easy to control. It contains chromium, cadmium, nickel, copper, zinc, gold, silver and other heavy metal ions and cyanide, some of which are carcinogenic, teratogenic, and carcinogenic. Mutated and highly toxic substances,...

AI Technical Summary

Problems solved by technology

[0003] At present, the following problems exist in the process of environmental protection treatment of electroplating wastewater: a. Due to the fact that there may be floating debris such as plastics and leaves in the electroplating wastewater during the production process, if the floating debris such as plastics and leaves are not removed in time, it may cause serious problems. Causes blockage of the filtration equipment, affects the smoothness of the subsequent filtration and disinfection of electroplating wastewater, and leads to poor environmental protection treatment of electroplating wastewater. b. During the filtration process of electroplating wastewater, impurities with large diameters inside may cause blockage inside the filter mechanism , causing the filtration flow rate of electroplating wastewater to slow down, affecting the filtration efficiency of electroplating wastewater, and indirectly causing the subsequent slowdown in the treatment efficiency of heavy metal and cyanide waste
