Section 1: Overview of Building Drainage Systems.
Second, the composition of the building drainage system
In the reinforced concrete forests of modern cities, building drainage systems play a vital role. It is not only about the daily life of every household, but also about the environmental health and sustainable development of the entire city. Next, let's step into the world of building drainage systems and explore its composition and subtleties.
1. We want to mention the sewage (waste) water collector. These humble appliances are the first line of defense in the drainage system, collecting wastewater from domestic and industrial areas and laying the foundation for subsequent treatment. Whether it's the sink in the kitchen or the shower in the bathroom, it's an important part of this process.
2. The drainage pipeline system is used as a transportation medium to transfer wastewater to the designated place safely and efficiently. This system is composed of horizontal branch pipes, risers, horizontal trunk pipes and other elements, and their design and layout are directly related to the smoothness of the entire drainage process.
3. The ventilation tube system is the "respiratory organ" that maintains the health of the pipeline. It ensures the long-term stable operation of the drainage system by removing harmful gases and keeping the air in the pipeline fresh, thereby preventing pipe wall corrosion and water seal damage.
4. The setting of the clearing equipment is also indispensable. Facilities such as inspection ports, cleaning ports, and inspection wells make the maintenance of drainage pipelines easier and faster, and provide convenience for daily cleaning and emergency repair.
5. For those low-lying areas, the pumping equipment is particularly important. Equipment such as sewage pumps and sumps can effectively lift sewage, ensure the normal operation of production and life, and also protect our environment.
6. Local treatment structures are the key links in the pretreatment of special sewage. For wastewater containing strong acids, alkalis or other harmful substances, these facilities can initially improve water quality and avoid pollution to the external environment.
Equally important is the outdoor drainage system, which consists of a drainage network and a sewage treatment system to ensure that urban rainwater and domestic wastewater are properly distributed and treated.
In conclusion, the building drainage system is a complex and sophisticated engineering system, which requires the attention and maintenance of each of us. By understanding these components, we can not only better enjoy the conveniences of modern life, but also contribute to the sustainable development of cities.
The next lecture is about the knowledge points, and the system of the building drainage system.
