上虞二水厂的处理规模为5万m~3/d,以地面水为水源;采用混合器混合、机械和折板相组合的长流程反应、折式平流沉淀、虹吸三阀滤池过滤工艺;并将各净水构筑物作密集型布置,用地指标每m~3水仅0.284m~2。该工程建成运行以来,出水浊度始终保持在1度以下。 The treatment capacity of Shangyu No. 2 Water Plant is 50,000 m 3 /d, with surface water as the source of water; the long process reaction, folded advection, and siphoning three-valve filter filtration process using mixer mixing, mechanical and folding plates And the water purification structures are arranged intensively, and the land use index is only 0.284m~2 per m~3 water. Since the project was completed and operating, the effluent turbidity has remained below 1 degree.
