The electroplating wastewater treatment process of Wuxi Leide Environmental Protection Equipment Co., Ltd. has been improved on the basis of traditional chemistry. According to the diversity of electroplating species and the complexity of wastewater components, combined with the actual operation status of electroplating plant, a series of new processes for the treatment of heavy metal wastewater in electroplating plant have been developed. It fundamentally solves the problem of substandard electroplating wastewater treatment, ensures the stable discharge of effluent up to the standard, creates economic benefits for customers with less and micro discharge, and reduces the payment of sewage charges (taxes), so as to win the recognition of users.
