From the perspective of building ventilation system construction, some materials need to be used and installed after air duct treatment. In the process of building acceptance, it also has a great advantage. The characteristics of ventilation effect are updated, and it is noted that at present, the construction technology advantage of the building is more and more obvious, which can be grasped in a new way. Therefore, for this kind of processing technology, it can reach the most perfect standard. Pay attention to the approval of pipeline technology.

　　在通风系统中输送气体的管道被称为风管，它将系统中的各种设备或部件连接成一个整体。为了提高系统的经济性，山东地区风道内的气流速度应合理选择，管道应短而直。风管通常由表面光滑的材料制成，如:薄钢板、PVC板，有时也用混凝土、砖等材料制成。

　　The pipe conveying gas in the ventilation system is called the air pipe, which connects various equipment or components in the system into a whole. In order to improve the economy of the system, the air velocity in the air duct of Shandong area should be reasonably selected, and the pipeline should be short and straight. Air ducts are usually made of smooth surface materials, such as steel sheet, PVC plate, and sometimes concrete, brick and other materials.

　　作为业内知名的环境治理综合解决方案提供商，在流域治理方面拥有国内外的技术和丰富的运营经验。根据周围环境和生态湖泊水质特点，山东通风管道及业主的发展规划，制定了完整的生态系统建设规划，对湖泊水质进行控制和修复。施工团队凭借丰富的操作经验和严格的施工规范，仅用一个月时间完成了生态系统主体的施工，并顺利通过了初步验收。目前，湖内及周边排水区域水质得到有效改善，山东通风管道服务得到业主及当地居民的一致认可。

　　As a well-known comprehensive solution provider of environmental governance in the industry, it has leading professional technology and rich operation experience at home and abroad in Watershed Governance. According to the characteristics of surrounding environment and ecological lake water quality, the development plan of Shandong ventilation pipeline and the owner, a complete ecological system construction plan has been formulated to control and repair the lake water quality. With rich operation experience and strict construction specifications, the construction team completed the construction of the main body of the ecosystem in only one month and successfully passed the preliminary acceptance. At present, the water quality in the lake and surrounding drainage areas has been effectively improved, and the ventilation pipeline service in Shandong Province has been unanimously recognized by the owners and local residents.

　　供气管道和回气管道的质量要求存在较大差异。一般来说，供气管道一般密封良好，山东通风管道材料也很好(一般使用专用铁管)，与回气管道不同。干墙、实木、中空塑料板等常用在回风管道中。一般情况下，回风管道存在一定的漏风现象。在管道清洗中，管道泄漏自然会导致吸力显著降低，这将极大地影响管道清洗的质量。因此，对供气、回风管道的混合清洗不仅会导致对回风管道的清洗不干净，还会导致对供气、回风管道的清洗不干净。

　　The quality requirements of gas supply pipeline and return pipeline are quite different. Generally speaking, the gas supply pipeline is generally well sealed, and the material of Shandong ventilation pipeline is also very good (special iron pipe is generally used), which is different from the return pipeline. Dry wall, solid wood, hollow plastic board, etc. are often used in return air duct. In general, there is a certain air leakage in the return air pipe. In pipeline cleaning, pipeline leakage will naturally lead to a significant reduction in suction, which will greatly affect the quality of pipeline cleaning. Therefore, the mixed cleaning of air supply and return pipes will not only lead to unclean cleaning of return pipes, but also lead to unclean cleaning of air supply and return pipes.
