- Abstract:
- Due to the change of hazardous waste materials and the adjustment of production process in a hazardous waste disposal plant, the wastewater from workshop is different from the designed wastewater. Consequently, the original process of the wastewater treatment station cannot meet the actual needs. According to the practical wastewater quality and the effluent requirement, the wastewater treatment station was transformed. The frontend physico-chemical pretreatment was transformed into Fenton pretreatment for high concentration wastewater, the secondary clarifier after biochemical tank was transformed into aerobic tank and MBR tank, and the disinfection tank was transformed into deep oxidation tank. It was showed that the process had stable effluent quality which could meet the discharge standard.
