- Abstract:
- Health service station is a place in which close contacts with the COVID-19 and other key populations are centralized quarantined for medical observation. A newly built health service station is equipped with 4 700 beds and a supporting sewage treatment station with a designed treatment scale of 2 200 m3/d. The treatment process consists of enhanced biological treatment system, sewage virus disinfection and sterilization system, aerosol disinfection and sterilization system and sludge disinfection and sterilization system. After treatment, the effluent and waste gas can meet the limit specified in Discharge Standard of Water Pollutants for Medical Organization (GB 18466-2005). The average COD, NH3-N and SS in effluent are 14.53 mg/L, 1.26 mg/L and 9.11 mg/L, respectively, and the average concentrations of H2S, NH3 and odor at the outlet are 0.01 mg/L, 0.8 mg/L and 6.3, respectively. The sludge is disinfected regularly and then transported outside for disposal. This project can provide reference for sewage treatment design of emergency medical temporary isolation and observation facility and cabin hospital.
