[0002] The wastewater discharged by the hospital mainly comes from the examination room, laboratory, operating room, X-ray room, ward, laundry room, canteen, etc. In addition to organic matter, foreign matter and suspended solids, the wastewater also contains a variety of bacteria, viruses and parasite eggs.

[0003] Current hospital wastewater treatment devices involve pouring hospital wastewater and wastewater treatment agents into the tank together. Then, a mixing device is used to stir and mix the hospital wastewater with wastewater treatment agents such as aluminum salts, iron salts, and flocculants. The wastewater treatment agents separate floating matter, sediment, and other substances dissolved in the water from the hospital wastewater. However, foreign matter needs to be filtered first, otherwise it will affect the contact between the wastewater treatment agents and the wastewater. Therefore, a harmless wastewater treatment tank for hospital wastewater treatment is proposed. Utility Model Content
