Urban rainwater treatment system
The invention discloses an urban rainwater treatment system. The urban rainwater treatment system comprises a grass planting ditch connected with an urban rainwater collection ditch and a water reservoir for storing rainwater, a drainage ditch is arranged beside the grass planting ditch, an isolation wall is arranged between the grass planting ditch and the drainage ditch, the grass planting ditchcomprises a gravel filter layer at the bottom, a water isolation layer in the middle and a planting layer at the upper part, the planting layer comprises a plurality of grass planting buckets with plants planted and arranged at intervals, gravel is filled between every two adjacent grass planting buckets, a plurality of water passing holes are formed in the isolation wall from top to bottom, thewater reservoir is arranged near the end of the grass planting ditch, a drainage pipe is arranged between the gravel filter layer at the lower part of the grass planting ditch and the water reservoir,a drainage port communicating with a municipal rainwater pipe is formed in the side wall of the drainage ditch, and the height of the drainage port is not lower than that of the isolation wall. According to the urban rainwater treatment system, the rainwater treatment efficiency can be effectively improved, the expansion of rainwater accumulation is facilitated, urban waterlogging caused by rainwater is avoided accordingly, and the reuse of rainwater accumulation is facilitated.
本发明公开了一种城市雨水处理系统，包括与城市雨水收集沟渠相连的植草沟、用于蓄积雨水的蓄水池，在植草沟的旁侧设有排水沟，在植草沟和排水沟之间设有隔离墙，所述植草沟包括底部的砾石过滤层、中部的隔水层和上部的种植层，所述种植层包括若干间隔设置并种有植物的植草桶，相邻的植草桶之间填充有砾石，隔离墙从上至下地设有若干过水孔，蓄水池设置在靠近植草沟端部处，在植草沟下部的砾石过滤层与蓄水池之间设有排水管道，在排水沟的侧壁设有与市政雨水管道相连通的排水口，所述排水口的高度不低于隔离墙的高度。本发明可有效地提升雨水处理效率，便于扩大雨水蓄积量，从而避免雨水造成城市内涝，并且方便蓄积雨水的再次利用。
