It integrates all kinds of data and information to achieve comprehensive monitoring and management of the wastewater treatment process. Through the smart water system, managers can grasp the operation status of sewage treatment plants in real time, and identify and solve potential problems in a timely manner. In addition, the smart water system can also provide data analysis, alarm prompts and other functions to help managers make more informed decisions.
Application of BIM technology
BIM technology plays an important role in the design, construction, and operation and maintenance phases of wastewater treatment plants. Through BIM technology, designers can better understand the process flow and building structure of the wastewater treatment plant, and achieve accurate design and optimized layout. In the O&M phase, BIM technology can help O&M personnel better understand equipment performance and operating status, and improve O&M efficiency and quality. In addition, BIM technology can also realize the digitalization, informatization and intelligent management of all aspects of sewage treatment plant design, construction, operation and maintenance.
Construction of digital management platform
The sewage treatment plant is actively building a digital management platform to realize the automatic monitoring and management of the sewage treatment process. These platforms can monitor the operating status and effluent quality of wastewater treatment equipment in real time, and automatically adjust the treatment process and equipment parameters according to the actual situation. At the same time, the digital management platform can also provide data analysis, alarm prompts and other functions to help managers find and solve problems in a timely manner.
The practice and application of BIM technology in sewage treatment plants
BIM technology is one of the important tools in the digital transformation of wastewater treatment plants. It integrates the design, construction, operation and maintenance of sewage treatment plants through digital means to achieve information management throughout the life cycle.
1. Design stage
1) Collaborative design to reduce pipeline collisions:
BIM technology can coordinate and solve collision problems of various disciplines in the design stage in a timely manner. The design of sewage treatment plants covers process, structure, construction, water supply and drainage, HVAC, electrical and other disciplines, and in the traditional two-dimensional design process, there are often collisions between various disciplines due to the lack of communication between various disciplines, such as the collision between pipes and beams and columns. With BIM technology, conflicts between disciplines can be reconciled at the design stage, reducing changes and rework in subsequent construction.
2) Accurate calculation to reduce cost waste:
There are many monomers in the sewage treatment plant, the process is complex, and the pipeline fittings and equipment required for the project are diverse. Traditional two-dimensional design requires technical and economic professionals to calculate the engineering quantity, which is cumbersome and cannot guarantee the accuracy of calculation. When the scheme changes, the quantity in the material table will be automatically updated with the change of the model, providing more intuitive data display for material procurement, prefabrication and cutting, making the material supply more convenient, and can also effectively assist manual control, save materials and reduce costs.
3) Simulation analysis and optimization of the design scheme
BIM technology can simulate the operation of different design schemes and help decision-makers formulate more reasonable design schemes. For example, in the design of V-shaped filters, the phenomenon of uneven water distribution in V-shaped tanks often occurs, and CFD simulation can be used to compare the hydraulic simulation performance of various water inlet and distribution facilities, and the optimal design scheme can be selected.
2. Construction phase
1) Visual disclosure to ensure the quality of construction
Through BIM and virtual reality (VR) technology, line-type drawings can be transformed into three-dimensional three-dimensional models and displayed in front of people, solving the problem of disconnection between two-dimensional drawings and three-dimensional reality. For complex nodes, with the help of construction process simulation, equipment installation simulation animation and BIM model, the construction personnel are visualized and disclosed, and the construction difficulties and key points are communicated with the construction personnel in a timely manner, which improves the interaction and feedback, ensures the construction according to the drawings, standardizes the construction, and ensures the construction quality.
2) Precise construction, saving materials
The use of BIM technology for electromechanical modeling can detect pipeline problems in time and carry out accurate construction through correct elevation and coordinates. This not only saves material, but also reduces rework and increases construction efficiency.
3) Collision detection to avoid secondary construction
Relying on BIM software for collision detection, the collision problems between electromechanical and electromechanical, electromechanical and structure, and structure and structure can be found, so as to avoid secondary construction and save construction period.
3. O&M phase
1) Digital monitoring and management
BIM technology can realize the digital monitoring and management of buildings and equipment, timely feedback of operating data and prediction of possible failures. This helps the wastewater treatment plant to achieve stable operation and reduce O&M costs.
2) Optimize maintenance schedules and workflows
With BIM technology, equipment health can be monitored in real time to optimize maintenance schedules and workflows. By predicting equipment life and failure modes, maintenance plans can be made in advance, extending equipment life and reducing O&M costs.
3) Data sharing, which is conducive to construction management
The informatization and intelligent management of BIM technology can achieve information sharing in the construction process and help engineers understand the progress of the project more effectively and in real time. At the same time, in the process of factory prefabrication and on-site installation, the centralized civilized construction and safety management of the prefabricated processing plant through the application of BIM technology make the installation process more procedural and standardized, and truly achieve visual and intelligent management of engineering construction.
In practice, the application of BIM technology has achieved remarkable results in many sewage treatment plants. For example, through the introduction of BIM technology, the Beihu Wastewater Treatment Plant has successfully built a smart construction site management system, realized information sharing and collaborative operation during the construction of the project, and greatly improved the construction efficiency and project management level. At the same time, BIM technology also provides strong support for the O&M phase, enabling the O&M team to grasp the equipment status in real time, optimize O&M strategies, and further improve O&M efficiency.
