摘要:
华南地区某水厂以水库水为水源，设计供水能力为6 000 m3/d。针对春秋季水源藻类含量高、浊度低，夏季暴雨后浊度高的情况，采用星伞絮凝+浮沉+自冲洗过滤一体化净水设备，利用星伞填料絮凝形成大量微涡旋提高絮凝效果；通过切换运行气浮或沉淀工艺，解决了滤池易堵塞、反冲洗周期缩短，以及气浮处理高浊度原水时效果差、水质不达标等问题。实际运行表明，在高藻期运行气浮工艺，当藻含量为8.32×107 个/L时，对藻类的去除率>98%；在高浊期运行沉淀工艺，当进水浊度为 772.8 NTU时，出水浊度最高为2.15 NTU。该项目总投资为380万元，制水成本为0.72元/m3，自投产以来，供水水质、水量均达到设计目标。
Abstract:
In the southern region of China, a waterworks utilizes a reservoir as its primary water source, boasting a designed water supply capacity of 6 000 m3/d. Due to the high algae concentration and low turbidity observed during spring and autumn, as well as the increased turbidity following summer rainstorms, an integrated water purification system featuring star-umbrella flocculation, flotation and sedimentation, and self-cleaning filtration has been implemented. The star-umbrella fillers are employed for flocculation purposes, generating numerous micro-vortices that can enhance the flocculation effect. By switching the operation of the air flotation or sedimentation processe, the system effectively addresses challenges such as filter blockage, shortened backwashing cycles, poor performance of air flotation in treating high turbidity raw water, and substandard water quality. Operational data indicates during the high-algae period, when the algae content is 8.32×107 cells/L, the removal rate of the air flotation process exceeds 98%. During the high turbidity period, when the turbidity reaching 772.8 NTU, the sedimentation process is operated, and the maximum turbidity of the effluent is 2.15 NTU. The total investment of this project is 3.8 million yuan, and the water production cost is 0.72 yuan/m3. Since its commissioning, both the quality and quantity of supplied water have consistently met design requirements.
