Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a medical wastewater treatment device with a sewage discharge mechanism. Background Art

[0002] Medical wastewater refers to sewage discharged from hospitals (general hospitals, specialized hospitals and other types of hospitals) into the natural environment or urban pipelines. The water quality varies with the nature, scale and location of the hospital. The amount of sewage discharged per bed per day is about 200-1000L. The main pollutants contained in medical wastewater are: pathogens (parasite eggs, pathogenic bacteria, viruses, etc.), organic matter, floating and suspended matter, radioactive pollutants, etc.

[0003] In the process of medical wastewater treatment, it is necessary to add flocculants to the wastewater to flocculate the flocs inside it. After sedimentation, the flocs and wastewater are separated. The separated wastewater is sent to other processes for harmless treatment. The flocs will form sludge in the sedimentation tank and settle at the bottom of the sedimentation tank. The sludge at the bottom of the sedimentation tank will accumulate more and more as the medical wastewater treatment time goes by. The accumulated sludge will not only cause the volume of the sedimentation tank to decrease, affecting the efficiency of wastewater treatment, but also be time-consuming and labor-intensive to clean up.
