Project Description:
The wastewater in this project comprises diverse and complex components, subject to stringent discharge standards.
Nitrogen-Phosphorus & Heavy Metal Wastewater: Treated through evaporation processes to achieve zero liquid discharge (ZLD).
Grinding Wastewater: Recycled via advanced treatment, with produced water meeting makeup water requirements for purified water production systems, effectively reducing wastewater discharge.
Integrated Wastewater: Post-treatment effluent complies with Level III discharge standards specified in Table 4 of the Integrated Wastewater Discharge Standard (GB 8978-1996).
