- 摘要:
- 广州北部水厂总规模150×104 m3/d，一期设计规模60×104 m3/d，是目前国内建成的最大规模超滤水厂。大型自来水厂设计应充分考虑工艺技术先进可靠、应急安全供水的目标和经济合理的节能减排需要。经多角度研究论证，该厂设计采用常规工艺+臭氧-生物活性炭+超滤+消毒工艺。工艺流程中设置了多处超越管线，可灵活地组合调度运行，降低运行成本；此外，设置了原水监测预警及多种药剂投加系统，可应对原水突发性水污染事故，确保水厂的安全运行。工程总投资25亿元，其中超滤部分2.7亿元，超滤单元运行成本为0.18 元/m3。
- Abstract:
- The total scale of Beibu Waterworks in Guangzhou is 1.5 million m3/d, and the design scale of the first stage is 600 000 m3/d. It is the largest ultrafiltration water plant in China. The process route of large-scale water plant should take full account of the advanced and reliable technology, the goal of emergency safe water supply and the need for rational energy conservation and emission reduction. After multi-angle research and demonstration, conventional process, ozone-bioactivated carbon, ultrafiltration and disinfection process were used. A number of transcend pipelines were set during the process, which can combine scheduling operation flexibly, and reduce operating costs. Besides, raw water monitoring, early warning and a variety of pharmaceutical feeding systems were set up to deal with sudden water pollution accidents from raw water and ensure the safe operation of water plant. The total investment of the project was 2.5 billion yuan, of which 270 million yuan was ultrafiltration part, and the operating cost of the ultrafiltration unit was 0.18 yuan/m3.
