Engineering Design Discussion for Petrochemical Wastewater Reuse Project

The pollutants discharge can be reduced and mass industrial water can be saved if the petrochemical wastewater is reused as makeup water of recirculating cooling water, which has great economical benefit and environmental benefit. In engineering design, the common wastewater treatment processes and advanced treatment processes are compared according to the influent character and effluent requirement, and one reasonable process line is chosen. After appropriate first preliminary treatment, secondary biological treatment and advanced treatment, most of the pollutants in wastewater can be removed and the effluent can be reused as the makeup water of recirculating cooling water.
