- 摘要:
- 在世园会、冬奥会落户以及京津冀协同发展、城乡供水一体化和农村饮水提质增效的背景下，北方某城市平原区兴建了地表水供水工程。该工程总规模9×104 m3/d，分为近、远两期。远期工程在近期工程的基础上实施，净水厂占地约2.78 hm2，设计规模5.5×104 m3/d。根据《生活饮用水卫生标准》（GB 5749—2022），并结合原水水质，净水厂采用预氧化+气浮+过滤+臭氧活性炭深度处理+紫外联合氯消毒的工艺流程，通水后出水各项指标均稳定达标。
- Abstract:
- A surface water supply project was launched in the plain area of a northern city against the backdrop of the World Horticultural Exhibition and the Winter Olympic Games being held in the city, along with the coordinated development of the Beijing-Tianjin-Hebei region, the integration of urban and rural water supply systems, and the enhancement of rural drinking water quality and efficiency. The total designed capacity of the project is 9×104 m3/d, and its implementation is divided into two phases: short-term and long-term. The long-term project will be implemented building upon the foundation of the short-term project. The water purification plant spans an area of approximately 2.78 hm2 and has a designed treatment capacity of 5.5×104 m3/d. In accordance with Standards for Drinking Water Quality (GB 5749-2022) and taking into consideration the quality of the raw water, the water purification plant employed a treatment process consisting of pre?oxidation, air flotation, filtration, ozone-activated carbon advanced treatment, and ultraviolet combined with chlorine disinfection. After the system was put into operation, all effluent parameters were stably in compliance with the limit specified in the standard.
