1. Wastewater Types and Treatment Solutions
Metal surface treatment wastewater is mainly divided into heavy metal wastewater and non-heavy metal wastewater according to pollutant characteristics.
1.1 Heavy Metal Wastewater Treatment
Heavy metal wastewater is commonly generated from electroplating, metal finishing and surface treatment processes.
The main pollutants include:
To effectively remove heavy metal pollutants, the treatment process includes:
Physicochemical Reaction → Batch Precipitation → Filtration → Heavy Metal Capture → Membrane separation
Through multiple treatment stages, the system reduces heavy metal concentration and improves wastewater discharge stability.
1.2 Non-Heavy Metal Wastewater Treatment
Non-heavy metal wastewater mainly contains:
Acidic substances
Alkaline substances
COD pollutants
The treatment process includes:
Acid-Base Regulation → Batch Precipitation → Filtration → Hydroxyl Radical Oxidation
The advanced oxidation process helps degrade organic pollutants and improves overall wastewater purification performance.
