The theory of vacuum drainage still needs further research so that this technology can be applied in more projects. The development prospects of five vacuum sewage systems At present, China's sewage is generally discharged by gravity drainage system. It collects the sewage from various buildings and transports it to the sewage treatment plant through pipelines. After treatment, it is discharged to rivers and lakes. Where there is no sewage treatment plant, the sewage is discharged into the water bodies after being treated in the septic tank. In areas where sewage networks are not widely used, such as rural areas, dry toilets are mostly used. Due to the poor sealing of the sewage pipe network, serious leaks may occur and it is easy to cause pollution to the surrounding environment. At the same time, with the extension of the pipeline, the pipeline is covered with more and more soil, not only the excavation volume is large, but also need to be set up in some places. The cost of pipe network and equipment is high. The research and development of vacuum sewerage system can overcome the shortage of gravity pipe network, and the effect of water saving can also be greatly improved. When the application of the vacuum sewage system reaches a certain scale, it can also develop a biological fertilizer system. China is a water-scarce country with low penetration rate of the drainage pipe network. The vacuum drainage system has a good development prospect in China. Six Problems Existing A new type of environmental protection technology, applied to civil construction, involves thousands of households and is closely related to people's lives. The transport mechanism of vacuum sewage needs further research. The serialization and standardization of vacuum toilets, valve parts, and vacuum stations, and the standardization of vacuum pipe network design and installation work also need to continue. The extension of the results of laboratory theoretical research to the application of practical engineering also needs to be raised by people’s awareness of environmental protection and government support.
