A certain electronic enterprise generates a large amount of industrial wastewater containing PCB circuit board wastewater every day, which needs to be treated to meet discharge standards. The company collaborated with an environmental protection company to design and install a 500 ton/day PCB circuit board wastewater treatment equipment.

This device adopts a technology route that combines advanced physical and chemical methods with biological treatment methods, mainly including three stages: pretreatment, biological treatment, and deep treatment.
1. Preprocessing stage:
; 1. Grille: Remove large particles such as PCB board fragments, metal particles, etc.
2. Regulating pool: regulating the amount and quality of sewage to ensure that it can enter the subsequent treatment unit evenly.
3. Coagulation reaction tank: By adding coagulants, suspended solids and colloidal substances in wastewater are removed.
4. Slant sedimentation tank: Separate suspended solids and flocs in sewage to further clarify it.

2、 Biological processing stage:
1. Hypoxia pool: Under anaerobic conditions, anaerobic bacteria are used to decompose organic matter, preparing for subsequent aerobic treatment.
2. Aerobic tank: Under aerobic conditions, aerobic bacteria are used to decompose organic matter and carry out nitrification reactions to convert ammonia nitrogen into nitrate.
3. Sedimentation tank: Sediments the biologically treated wastewater to separate sludge and water.

3、 Deep processing stage:
1. Filter: Further remove suspended solids and impurities from wastewater.
2. Activated carbon adsorption: Using activated carbon adsorption to remove harmful substances such as organic matter and residual chlorine from wastewater.
3. Disinfector: Disinfect sewage to kill any bacteria and viruses that may exist.
4. Clear water tank: stores treated wastewater for reuse or discharge.
The device runs stably and can effectively treat PCB circuit board wastewater, meeting discharge standards. At the same time, the device also has the advantages of high automation, easy operation, and convenient maintenance.
