- 摘要:
- 为应对城市快速发展带来的饮用水供需矛盾问题，提升水厂保障水质安全的能力，深圳市长流陂水厂于2018年8月进行了4期网格絮凝池提升工程改造，主要是应用水力旋流絮凝器进行技术提升和池体改造，在不同絮凝段增加水力旋流网格絮凝器，改造后运行效果显著，实际产水量由8×104 m3/d增至10×104 m3/d，沉后水浊度保持在0.41 NTU左右，增加水量的投资为55元/m3，PAC制水成本下降了0.005元/m3。此项工程改造内容少，无新增建设用地，投资成本低，产能提升明显，水质保障效果好，可为类似用地紧张的自来水厂产能提升改造提供参考。
- Abstract:
- In order to cope with the contradiction between drinking water supply and demand brought by rapid urban development and improve the waterworks’ ability to guarantee water quality and safety, the fourth phase upgrading project of grid flocculation tank was carried out in Shenzhen Changliupi waterworks in August 2018. The hydrocyclone grid flocculator was added in different flocculation sections for technical upgrading and the tank functional transformation. The operation effect after transformation is remarkable, the actual production capacity of the waterworks is increased from 8×104 m3/d to 10×104 m3/d, and the water turbidity after sinking is kept at about 0.41 NTU. The unit investment for incremental water volume is 55 yuan/m3, and the unit water production cost of PAC has dropped by 0.005 yuan/m3. This project has few reconstruction contents, no additional construction land, low investment cost, obvious capacity improvement, and good water quality guarantee effect, which provides a reference for the improvement of similar waterworks with limited land use.
