沙头角水厂运行已近二十年,工艺及设备等问题导致其应对多水源水质变化能力不足,水质生物安全风险性较大。为此,水厂通过升级改造,建立了以活性炭—超滤为核心的净水工艺流程。运行一年多的结果表明,新工艺运行稳定,出水浊度<0.1NTU,耗氧量去除率超过50%,出厂水细菌和浮游生物数量为0。水厂应对原水水质突变能力明显提升。
Shatoujiao Water Works has been in operation for nearly 20 years. Problems such as technology and equipment have led to its lack of capacity to respond to changes in water quality of multiple water sources and greater risks to biological safety in water quality. To this end, the water through the upgrading, the establishment of activated carbon - ultrafiltration as the core of the water purification process. The result of more than a year of operation shows that the new process is stable, the effluent turbidity is less than 0.1 NTU, the oxygen consumption removal rate is over 50%, and the quantity of bacteria and plankton in the exiting water is zero. Water plant to respond to abrupt changes in water quality improved significantly.
