Description
Technical Field
[0001] This utility model relates to the field of drainage purification technology, and in particular to a purification device for building water supply and drainage. Background Technology
[0002] A building water supply system is a cold water supply system that introduces water from the municipal water supply network or a self-supplied water source network into the building, distributes it through water distribution pipes to domestic, industrial, and fire-fighting water equipment, and meets the water quantity, pressure, and quality requirements of each water point. A building water supply and drainage system actually includes two aspects: the building water supply system and the building drainage system. The building drainage system is responsible for removing sewage from residential, public, and industrial buildings. An internal building drainage system generally consists of water receivers for sanitary fixtures or industrial equipment, drainage pipes, cleaning facilities, venting pipes, wastewater lifting equipment, and local treatment structures. Internal building drainage systems are classified into single-riser drainage systems, double-riser drainage systems, and triple-riser drainage systems based on the configuration of drainage risers and venting pipes. The sewage discharged by the building drainage system must meet the sewage discharge conditions stipulated in relevant national regulations and standards.
[0003] During the process of building roof drainage, a lot of debris often accumulates on the roof due to wind and rain. If the debris is not treated during the drainage process, it will cause the drainage pipe to become blocked. Therefore, a purification device for building water supply and drainage is proposed.
