摘要:
珠海桂山岛海水淡化工程设计规模为1 000 m3/d，采用微絮凝过滤+多介质过滤+两级精密过滤+反渗透（部分二级）的工艺流程。淡化产水主要进入桂山水库，与水库水混合经净水厂净化后外供。部分产水经二级脱盐、消毒后生产袋装水和桶装水。系统运行实践表明，一级反渗透平均回收率为43.37%，平均脱盐率为98.25%，电耗为3.30 kW·h/m3，回收率偏低，脱盐率和吨水电耗基本达到设计预期。该工程试产期间产水量为67 641.9 m3，占该岛当年水资源供应量的39.34%，有效替代了船运水，缓解了淡水资源短缺问题，节省了供水成本。
Abstract:
The Guishan Island seawater desalination project in Zhuhai, with a design capacity of 1 000 m3/d,employs a process flow that includes micro-coagulation filtration, multi-media filtration, two-stage precision filtration, and reverse osmosis(with partial secondary treatment). The desalinated water is primarily fed into the Guishan Reservoir, where it mixes with reservoir water before undergoing further treatment at a water treatment plant for external supply. A portion of the product water is subjected to secondary desalination,purification,and disinfection to produce bottled and barreled water. System operation indicates that the average recovery rate of the first-stage reverse osmosis is 43.37%, the average desalination rate is 98.25%,and the specific power consumption is 3.30 kW·h/m3. Although the recovery rate is relatively low,the desalination rate and specific power consumption meet the design expectations. During the trial production period, the project produced 67 641.9 m3 of water, accounting for 39.34% of the island’s annual water supply. This effectively replaced water transported by ship, alleviated the shortage of freshwater resources, and reduced water supply costs.
