Advances in Resources and Environmental Science

Electroplating is widely used in industrial production, but the wastewater it generates contains high concentrations of heavy metal ions, organic pollutants, and complex compounds, posing serious threats to the environment and human health. Traditional single-treatment methods cannot meet stringent discharge standards, necessitating the adoption of efficient and stable combined treatment processes. The electrocoagulation-biochemical synergistic process integrates multiple mechanisms, including electrochemical oxidation, metal hydroxide adsorption, and biodegradation, to collaboratively remove various pollutants from electroplating wastewater. By combining electrochemical oxidation, metal hydroxide coprecipitation and adsorption, and biodegradation, this process effectively eliminates heavy metals, organic pollutants, and complex compounds from wastewater. It offers advantages such as high treatment efficiency, stable operation, and strong adaptability, demonstrating promising application potential in practical engineering projects.
