Abstract

A hospital sewage treatment system, which belongs to the field of environmental protection, is characterized in that: hospital sewage is treated by septic tanks, sewage regulating tanks, hydrolytic acidification tanks, and biological aeration tanks, and then treated by MBR biofilm technology to separate mud and water. The clear water that comes out enters the disinfection tank, and enters the reclaimed water tank after ozone disinfection; the separated sludge is sent back to the hydrolysis acidification tank through the sludge return pump, and is degraded again. After the above-mentioned multi-level, multi-layer and comprehensive treatment, the harmful pathogenic microorganisms in the sewage are basically completely killed, and the water entering the reclaimed pool not only has no secondary pollution, exceeds the discharge standard stipulated by the state, but also can be used for secondary use; During the sludge treatment process, the organic matter in it is completely degraded, and no special treatment is required for the sludge; the system operates in a closed environment, and the harmful gases generated during the treatment process are sterilized by the ozone and ultraviolet disinfection devices in the exhaust pipe. After discharge, it will not pollute the air.
