基于供水安全保障的南宁市多水源系统规划与设计
Planning and Design of Nanning's Multi-Water Sources System Based on Water Supply Security
摘要
Abstract
[Objective]With the rapid development of the water supply industry in Nanning City in recent years,problems such as the safety of water source system,water environmental protection and growth of water demand faced by the city have become increasingly obvious.To improve the relatively single situation of the original water sources in Nanning City and solve the problems that affect the water supply security of large cities,such as the difficulty in environmental protection of the water intake points of the main water treatment plants(WTPs),the limited scale of raw water intake,and the weak emergency water intake guarantee capacity.[Methods]By studying from and drawing on experience of water source planning and construction in large cities at home,a systematic study was conducted on the hydrological characteristics of water sources in Nanning City and the planning and development features of the urban water supply system.The engineering planning and design were based on the requirements of water supply security guarantee and water supply volume development for raw water and emergency water supply systems.The system was characterized by"two rivers working together and serving as backups for each other",and it had complete functions such as the connection and dispatching operation of multiple water sources,long-distance energy-saving storage and regulation of raw water,and the pressure distribution of raw water by multiple WTPs.[Results]The project was divided into two phases.The first phase first addressed the conflicts in the water source protection areas of five WTPs in the central urban area.The second phase addressed various requirements such as urban water volume development and emergency support for multiple water sources.[Conclusion]The first phase of the project ingeniously utilize the favorable hydrological conditions of the existing Laokou Reservoir and the 17-kilometer large-section gravity flow tunnel water conveyance system,reducing the impact of the project construction on the underground space of the central urban area.At the same time,it also achieves the functions of short-term,low investment and low energy consumption water conveyance.The second phase of the project is based on a safety guarantee design plan of"equal scale and equal distance joint operation of dual water sources",which not only enhances the water intake capacity but also further avoids the threat of algae growth and the risk of sudden water source accidents at the tail end of the reservoir.It improves the water quality of urban raw water from the source and resolves the contradiction between the protection of urban water sources and urban construction and development.关键词
