Spraying wastewater treatment

    Spraying wastewater treatment: 

    Spraying wastewater mainly comes from pre-degreasing, degreasing, surface conditioning, phosphorization, passivation and other pretreatment processes of car body; and cathode electrophoresis, floating coating, and topcoating processes. The car spraying wastewater, especially the electropheric wastewater and painting wastewater, contains resin, surfactants, heavy metal ions, pigments and other pollutants which have complicated components, high concentration and poor biochemicalization. The spraying wastewater treatment mainly adopts divided treatment, coagulation precipitation, coagulation air floatation, sand filtration and other treatment methods. 

    The spraying wastewater mainly comes from process cleaning water and the main chemical components found in the process are: 

    Degreasing: suspended solids, oil dirt, surfactants, phosphate radical sodium salt, silicate radical sodium salt. 

    Pickling: hydrochloric acid, sulfuric acid 

    Surface conditioning: polyphosphates 

    Phosphorization: phosphate radical, zinc, and nickel, etc. 

     

    Project example: Hangzhou Xizi Forvorda's spraying wastewater treatment project 

    Designed duty of water: 72m³/D
