Description

Technical Field

[0002] Medical sewage is mainly discharged from the hospital's treatment rooms, laboratories, wards, laundry rooms, X-ray studios and operating rooms, and its source and composition are very complex. Hospital sewage contains a large number of pathogenic bacteria, viruses and chemical agents, and has the characteristics of space pollution, acute infection and latent infection. Sedimentation tanks are divided into horizontal sedimentation tanks and vertical sedimentation tanks according to the direction of water flow. The sedimentation effect is determined by the flow rate of water in the sedimentation tank and the residence time of water in the tank. After the sewage treatment is completed, a mud discharge mechanism is required to discharge the mud in the sewage from the sedimentation tank.

[0003] The existing sedimentation tanks for medical wastewater treatment still have some drawbacks. After long-term use, most sedimentation tanks will have a lot of impurities at the bottom, which are difficult to remove. This will cause the sludge pump to be blocked, affecting the normal sludge pumping work and reducing the use effect. For this reason, we propose a sludge discharge mechanism for sedimentation tanks for medical wastewater treatment. Utility Model Content
