Aluminum magnesium zinc plating factory

The Aluminum magnesium zinc plating factory involves acid washing,galvanizing,passivation and other processes,and the wastewater generated is complex in composition,including high concentrations of zinc ions,iron salts,organic acids and suspended solids.Traditional processing methods suffer from high costs and low resource recovery rates,and require process optimization to achieve a balance between environmental and economic benefits.
1.Acid washing wastewater:containing hydrochloric acid,ferrous chloride,and a small amount of zinc ions,with a pH value usually below.
2.Galvanized rinse wastewater:The Aluminum magnesium zinc plating factory contains sodium hydroxide,sodium zincate,trace amounts of heavy metals such as chromium and copper.
The concentration of zinc ions can reach 500-2000mg/L,and the concentration of iron ions can reach 1000-3000mg/L.The Aluminum magnesium zinc plating factory is strongly acidic,and the galvanizing wastewater is strongly alkaline.
The treatment of wastewater from aluminum magnesium galvanized sheet factories requires a combination of pretreatment,chemical precipitation,membrane separation,and deep treatment technologies to achieve heavy metal removal and water reuse.In the future,with the development of resource utilization technology,effective recycling processes such as ion exchange and electrochemical methods will further reduce processing costs and promote the green transformation of the industry.Aluminum magnesium galvanized sheet factories should regularly monitor Aluminum magnesium zinc plating factory,optimize process parameters,and ensure long-term stable and compliant discharge.
