Energy-saving sewage centralized purification device for hospitals

The utility model discloses an energy-saving sewage centralized purification device for hospitals. A chlorine dioxide generator is installed at one end of the virus and bacteria purification box, and a medicine supply pipe fitting is installed between the virus and bacteria purification box and the chlorine dioxide generator. By installing the corrosion-resistant metering pump and the like, when the device is used, wastewater subjected to pretreatment at all levels is installed on the device and can be intensively integrated into the storage tank in the purification chamber, the wastewater in the storage tank can be pumped into the virus and bacteria purification box, and the virus and bacteria can be purified by utilizing a liquid level sensor installed in the virus and bacteria purification box. The amount of wastewater to be treated introduced each time can be controlled, then the corrosion-resistant metering pump installed on the chemical supply pipe fitting is utilized, the automatic quantitative chemica
