Study of Wastewater Advanced Treatment and Reclaimed Water Reuse for a Large General Hospital

摘要

A combined process of biological aerated filter, fiber ball filter and chlorine dioxide disinfection was used to treat effluent of primary hospital wastewater in Jinan. Its treatment capacity was designed as 400 m3/d based on the reclaimed water demand of the large general hospital. The quality of the effluent can meet the requirements of the Reuse of Urban Recycling Water------ Water Quality Standard for Urban Miscellaneous Water Consumption (GB/T18920-2002). The project has less site area, low investment and operation cost and high automatic control level, so it can provide scientific references for design and operation of similar projects.
