Underground sewage treatment plants and green gardens on the ground have the advantages of less environmental pollution, high safety, constant underground temperature to avoid the instability of water quality caused by large temperature changes, making it easier for the water quality to reach the standards, and greatly utilizing land resources. For its small impact on the surrounding environment, the underground sewage treatment plants have become the first choice for new sewage treatment plants in China, where land resources are gradually scarce. However, considering the limitation of underground space and investment, the underground sewage treatment plant is compact in structure design and chooses a technology with relatively small area. Based on this, the previous underground sewage treatment plants mostly choose MBR process. While, the new generation MBR membrane technology PC-MBR has more advantages than MBR will replace the traditional MBR process, become the preferred underground sewage treatment plant.

With the acceleration of urbanization and the enhancement of residents' awareness of environmental protection, the aboveground sewage treatment plant not only purifies the sewage, but also pollutes the surrounding environment with the odor, noise and sludge produced by the sewage treatment plant, which makes the surrounding land depreciate and wastes the increasingly tense land resources. Underground sewage treatment plant has become a new favorite of sewage treatment plant construction because of its strong sealing, no secondary pollution, and the ground can be greening.

Underground sewage treatment plants are very popular in developed countries. The sewage treatment plants are hidden underground and the ground is like a garden.

The Henriksdal sewage treatment plant in Sweden, due to its special geological structure, can only be expanded on the basis of existing land. To this end, Stockholm chose the compact MBR technology as upgrading technology.

The Viikinmäki sewage treatment plant in Helsinki, Finland, was built in the 1990s. Due to the limited available space, the plant had to choose a compact biofilter when upgrading.

Oslo, Norway, is the fastest growing city in Europe. Bekkelaget underground sewage treatment plant.
