[0002] The vacuum drainage system of hospital buildings is an efficient, energy-saving and environmentally friendly sewage discharge system. Different from traditional gravity drainage, this system relies on the pressure difference between the atmosphere and the vacuum drainage system, and uses air to quickly enter the vacuum drainage system to produce a high-speed air-water mixture, and pushes the sewage into the drainage pipe under the action of forced suction, and then transports it efficiently; the main equipment of the vacuum drainage system is composed of vacuum pump stations, vacuum toilets, vacuum sewage buffers and vacuum pipes; hospital sewage has a complex composition and contains various pathogens and chemicals, which places extremely high demands on the drainage system. It not only requires efficient treatment, but also prevention of virus transmission and bacterial growth; therefore, the hospital vacuum drainage system has the advantages of water saving, emission reduction, odor isolation, and high space utilization, and is particularly suitable for buildings with compact structure, high sanitary requirements and complex spatial conditions.

[0003] In actual applications, there is a risk of frequent pipe blockage in the hospital vacuum drainage system, especially in outpatient and emergency buildings, infectious departments, biological laboratories and radiotherapy areas.
