If it is discharged directly without effective treatment, it will not only pollute the receiving water body and the surrounding environment, but even endanger human health.

目前医疗废水的处理方法有很多种，如公开号为CN205773964U的中国发明专利公开了一种医疗废水一体化处理系统，该系统包括污泥池、二氧化氯发生器以及依次连通的调节池、水解酸化池、缺氧池、接触氧化池、沉淀池和消毒池，调节池设有进水管和过滤医疗废水的格栅，水解酸化池，缺氧池和接触氧化池内均设有生物填料，沉淀池内安装有使废水沉淀的蜂窝斜管，消毒池连接有排水管；污泥池与沉淀池底部通过带有水泵的管道连通，二氧化氯发生器与消毒池通过管道连通。该设备将好氧、厌氧和缺氧单独设池，占地面积较大，缺氧好氧环境控制不便，同时后续仅采用二氧化氯消毒，对于医疗废水，对成分复杂的废水中的细菌病毒起到很好的杀灭作用，效果并不理想。At present, there are many kinds of treatment methods for medical wastewater. For example, the Chinese invention patent with the publication number CN205773964U discloses an integrated treatment system for medical wastewater. Acidification tank, anoxic tank, contact oxidation tank, sedimentation tank and disinfection tank, the adjustment tank is equipped with water inlet pipes and grids for filtering medical wastewater, hydrolytic acidification tank, anoxic tank and contact oxidation tank are all equipped with biological fillers, sedimentation tank A honeycomb inclined pipe for sedimentation of waste water is installed, and the disinfection tank is connected with a drainage pipe; the sludge tank is connected with the bottom of the sedimentation tank through a pipeline with a water pump, and the chlorine dioxide generator is connected with the disinfection tank through a pipeline. The equipment has separate pools for aerobic, anaerobic and anoxic, which occupy a large area, and it is inconvenient to control the anoxic and aerobic environment. At the same time, only chlorine dioxide is used for disinfection in the follow-up. The virus plays a very good role in killing, but the effect is not ideal.

此外，也有一些医疗废水处理装置内设有曝气装置，但是都是固定在底部曝气装置，拆卸、更换均不方便，且成本较高。In addition, some medical wastewater treatment devices are equipped with aeration devices, but they are all fixed at the bottom of the aeration device, which is inconvenient to disassemble and replace, and the cost is relatively high.
