Painting Wastewater Treatment Equipment Furniture factory painting wastewater treatment includes the following steps:
Wastewater collection: Wastewater generated by painting wastewater and workshop cleaning water is collected in a centralized wastewater pool.
Removal of paint residue: The wastewater in the wastewater tank is pumped into the grit remover tank, and the paint slag after sedimentation in the grit tank is cleaned regularly.
Regulate water quality and quantity: The effluent from the grit tank enters the regulating tank, and the function of the regulating tank is to balance the flow and concentration of wastewater to achieve the stability and effectiveness of subsequent treatment.
Coagulant flocculation: The effluent from the regulating pool is pumped into the paint mist coagulant reaction pool, the paint mist coagulant AB agent is added, and the agitator is fully stirred to form alum flowers to realize the condensation of paint particles.
Hydraulic screen: The wastewater after the coagulant reaction enters the hydraulic screen, and the larger suspended solids and sediments are filtered out through the screen.
Sedimentation separation: The effluent of the hydraulic screen enters the sedimentation separation tank to further precipitate the suspended solids and sediments in the wastewater.
Sludge dewatering: The sludge produced by the grit separation tank is regularly pumped to the sludge dewatering machine for dewatering treatment, and the dewatered sludge can be recycled or safely disposed of.
Wastewater reuse: The treated wastewater can be reused in production links such as workshop cleaning and spray tower cleaning to realize the recycling of water resources.
The above are the main steps of painting wastewater treatment in furniture factories, but the paint booth wastewater is different from company to company, so the specific steps may vary from company to company.
