临江水厂扩建工程设计

Design of extension project of Linjiang Waterworks in Shanghai

上海市临江水厂原设计规模40万m3/d,规划供水量为60万m3/d。临江水厂扩建工程引进高效ACTIFLO澄清池,设计上升流速可达50m/h,并采用TGV双层滤料滤池,确保出厂水锰≤0.2mg/L。为达到《上海市供水专业规划》2010年水质目标,除采用臭氧活性炭处理工艺外,还采用了UV消毒工艺以去除隐孢子虫和贾第虫。另外为满足上海市环保要求,对60万m3/d规模水厂的排泥水进行了浓缩、脱水处置。

For the extension project of Linjiang Waterworks in Shanghai, the capacity of this waterworks will be upgraded from 400 to 600 thousand cubic meters per day. New processes such as high efficient clarifier ACTIFLO with designed sedimentation velocity of 50 m/h and TGV filter with double filtrating layer are adopted to cut down the Mn content in output water to less than 0. 2 mg/L. Beside the ozone- activated carbon also the ultraviolet process will be adopted to remove Cryptosporidium and Giardia as required by the Plan of water supply in Shanghai for 2010. The waterworks sludge of this waterworks will be disposed by thickening and dewatering processes.
