The invention discloses a water backwashing water system building model, including drainage, clear water and clean water infiltration floor set directly in the rivers, the infiltration ditch and water pool connected by the through hole at the bottom of the clear water tank and water floor bottom are communicated through a pipeline; the permeability of both sides at the bottom of canal seepage channel with symmetric bell bell base, base is arranged on the bell, bell from the outside in a downward inclined seepage channel; pipe comprises a water inlet pipe, a backwashing pipe and a water outlet pipe, the outlet pipe is installed in the water and the bottom floor upstairs, water purification installation of horizontal centrifugal pumps, horizontal centrifugal pump is installed on the water inlet pipe; the water inlet pipe at one end and the other end is communicated with the clean water tank, and the outlet pipe; pipe is also provided with a backwashing water inlet pipe; one end of the pipe and backwashing with another clean water tank connected. The invention has the advantages of large flushing flow and strong water pressure, and can ensure the quality of the project and the backwash effect, and can save materials, reduce engineering cost and not clog easily.
【技术实现步骤摘要】
本专利技术涉及一种净水楼新型反冲洗的取水系统。
技术介绍
目前的净水楼普遍利用江河中砂卵石和砂卵石上层的滤膜作为天然过滤器,原水 经大自然中生物、物理和化学作用,水质达到清澈透明,无杂质。达到或优于生活饮用水标 准。取代了现有自来水净水工艺中凝集、絮凝、混合、沉淀、过滤、排污及污泥处置等多个步 骤,其原理是设计的净水楼、清水池、渗渠等取、净水构筑物均沿江河岸边平行布置。当净 水楼中的泵机组抽水时,使清水池、渗渠中水位下降,由于压力传导作用,这时河床水位与 清水池、渗渠等构筑物内的动水位产生压力差,诱使江河面原水下渗,水中的悬浮物等杂质 被过滤膜截住、吸附;然后被过滤膜所截住、吸附的悬浮物等杂质经江河明流水自然冲刷更 新,周而复始,保持过滤膜良性循环,从而使河床中的渗渠喇叭口生产出可持续、稳定地获 取优质自来水,经渗渠集中到清水池,通过净水楼泵机组一级输送给用户使用。由于先前采用的净水楼技术,包括在先专利CN100489202C公告的《一种净水楼滤 层中配用反冲洗的构筑方法》是要解决的是1、在净水楼下游附近建有拦河坝,人为改变河 道流向、影响流速,造成河床水位压力传导作用减弱,水流自然冲刷的速度、砂卵石层过滤 效果人为改变;2、枯水季节在净水楼上游附近大量淘沙,使河底沉积的淤泥、存渣等泛起水 面而沉积在滤膜上,造成河流中天然冲刷与沉积良性循环被人为改变,形成过滤膜上悬浮 物等杂质仅由江河明流水无力冲刷更新,明显影响净水楼产水量的情况下,在净水楼内配 备有反冲洗泵,和在净水楼外铺设有许多根独立的反冲洗管道,依次沿清水池以及渗渠等 构筑物上层砂卵石过滤层中浅 ...
