Abstract In view of the water quality characteristics of Corona Virus Disease 2019(COVID-19)medical wastewater, taking sewage treatment systems of Leishenshan hospital in Wuhan for example, the extermination of Corona Virus Disease 2019(COVID-19)is focused on. Secondary treatment process ″Pre-disinfection + MBBR biological membrane + coagulation sedimentation + baffle disinfection″ is adopted for Corona Virus Disease 2019(COVID-19)medical wastewater, wastewater treatment facilities in strict accordance with the <Water Pollution Discharge Standard of Medical Institution>(GB 18466—2005)and < Technical Specifications of Hospital Waste water Treatment Engineering >(HJ 2029—2013)is carried on the design,The effluent water quality meets the <Water Pollution Discharge Standard of Medical Institution>(GB 18466—2005). The treatment effect is stable, the virus inactivation rate is high, and the effluent water quality is good.This technology has the follo-wing advantages: the main part fully airtight and controlled by PLC is safe and reliable;All processing units are integrated equipment, fast construction speed, ready-to-use construction, flexible demolition, it convenient for remote reconstruction or large-scale capacity expansion transformation and suitable for all kinds of emergency engineering construction and construction of a short period of time project.
