The utility model relates to rainwater purification. In view of the problem that sludge accumulation at the bottom of the sedimentation tank leads to poor sedimentation effect, a sponge urban rainwater purification system is provided. The technical scheme is as follows: a sequentially connected sedimentation tank, a rainwater filter tank and a water storage tank are arranged in the sedimentation tank, in which a partition board dividing the sedimentation tank into an inlet part and a water filter part is arranged, and a channel is arranged at the bottom of the partition plate, and a water filter is arranged. There is a filter which rises and falls in the vertical direction, a sewage outlet on the water filter, and a push plate moving from the water inlet to the water filter at the bottom of the sedimentation tank. The height of the baffle is the same as the height of the channel. The sludge at the bottom of the sedimentation tank is pushed to the sewage outlet by push plate to collect and treat, so as to reduce the sludge and large particle impurities accumulated at the bottom of the sedimentation tank and facilitate the workers to treat the sludge at the bottom of the sedimentation tank, so as to ensure the sedimentation effect of the sedimentation tank and improve the sedimentation efficiency of the sedimentation tank.

一种海绵城市雨水净化系统
本技术涉及雨水净化,更具体地说,它涉及一种海绵城市雨水净化系统。
技术介绍
海绵城市,是新一代城市雨洪管理概念,是指城市在适应环境变化和应对雨水带来的自然灾害等方面具有良好的“弹性”,也可称之为“水弹性城市”。现有的海绵城市雨水净化是通过将雨水收集后排放至沉降池中以进行雨水中污泥以及大颗粒杂质的沉降,是对雨水的初级过滤,但是经过一段时间后,沉降池底部会聚集大量的污泥,会导致沉降池的沉降效果降低,则需要工人对沉降池进行清理,清理过程需要工人进入到沉降池中,操作不便,因此具有改进的空间。
技术实现思路
针对现有技术存在的不足,本技术的目的在于提供一种海绵城市雨水净化系统,具有方便清理沉降池底部污泥的优点。为实现上述目的,本技术提供了如下技术方案:一种海绵城市雨水净化系统,包括沉降池、雨水过滤池以及蓄水池,所述沉降池中设有隔板,所述隔板将沉降池划分为进水部以及滤水部,所述滤水部与雨水过滤池连通,所述隔板底部设有连通进水部以及滤水部的通槽,所述滤水部中设有沿高度方向升降的滤网,所述滤水部远离进水部的侧面上设有排污口,所述沉降池的底部设有从进水部朝滤水部并 ...
