What is the composition of the internal drainage system of the building?

Building drainage system usually includes external drainage system and internal drainage system, both of which have different functions and are also indispensable infrastructure for buildings. Next, we will introduce the components of the internal drainage system of the building.

1. Sanitary utensils or production equipment water receivers: mainly used to collect and remove sewage, the equipment includes accessories: toilet utensils, toilet utensils, bathing utensils, washing utensils and floor drains.

2. Drainage pipe system: According to the installation location, installation conditions, and the nature and composition of sewage, the drainage pipes used in this drainage system mainly include plastic pipes, cast iron pipes, glazed clay pipes, etc. If the discharge is industrial wastewater, Glass tubes, ceramic tubes, etc. can also be used.

3. Pumping and lifting equipment: If underground structures such as basements and civil air defense buildings in civil buildings cannot be discharged into the outdoor inspection wells, pumping and lifting equipment should be installed. Important matters such as the selection of sewage pump and the design of sewage pump house should be considered when constructing this equipment, so as to maintain a good indoor sanitation environment.

4. Clearing equipment: It is mainly used to dredge the drainage pipes inside the building to keep the drainage smooth. Usually includes inspection ports, cleaning ports, inspection wells and other equipment.

5. Structures for local and local treatment of sewage: generally include septic tanks, cooling tanks, oil traps and other equipment, which are used to treat sewage that cannot directly enter the urban sewers without treatment. Among them, the cooling pool mainly uses methods such as secondary evaporation, water surface heat dissipation, and cooling by adding cold water to remove the high-temperature sewage discharged from the heating equipment.

The main components of the building's internal drainage system have been introduced, and each component plays an irreplaceable role in the building's internal drainage system. I hope that through the above content, you can have some understanding of the internal drainage system of the building.
