重庆市人民供水公司北碚水厂以嘉陵江为水源,厂内二座三档转折式平流沉淀池于1965年技术改造时,设计能力为8000米~3/日,每档长29.53米,三档共长88.59米,池宽2.7米,有效水深2.4米。1970年,在平流沉淀池第一档的水流横断面上用条石修建一实心阻流墙图1,位置在沉淀池进口14.53米处,墙顶上水深0.38米。阻流墙迫使水流在配水花墙后逐渐缩小水流断面,并越过(溢
Chongqing People’s Water Supply Company Beibei Water Plant takes Jialing River as the water source, and the factory has two three-speed transitional advection sedimentation tanks. In 1965, the technical capacity was designed to be 8,000 meters to 3 days per day, with a total length of 29.53 meters. 88.59 meters long, 2.7 meters wide pool, effective depth of 2.4 meters. In 1970, a solid blockage wall was built on the cross-section of the first flow sedimentation tank in the first section of the sedimentation basin. The position was 14.53 meters above the entrance of the sedimentation tank. The water depth at the top of the wall was 0.38 meters. The obstructing wall forces the flow of water to gradually narrow the flow cross section after crossing the water wall, and over the overflow
