Project details: This project is a coking wastewater treatment project, which plans to adopt a 6-tower parallel treatment mode. The single tower has a treatment capacity of 20 cubic meters per hour, and a single tower discharges 1 cubic meter of carbon every 2 days. The COD is reduced from 130 mg/L to 80 mg/L, ensuring that the subsequent membrane process is not impacted and operates stably.
