Tidal river ecological purification island and backflushing sludge discharge method thereof
The ecological purification island comprises a clear water section, a rectification section, an ecological purification section and a water outlet section which are sequentially communicated in the length direction of the ecological purification island, and the clear water section comprises a one-way flow inlet, a sand settling area and a settling area, and the sand settling area and the settling area are sequentially arranged from bottom to top; the rectification section comprises water distribution holes; the ecological purification section comprises a water inlet distribution wall, a water inlet end filler protection layer, a purification filler, a water outlet end filler protection layer and a water outlet lattice wall which are sequentially arranged in the length direction of the ecological purification island; the water outlet section comprises a one-way outlet; the invention further provides a backflushing and sludge discharging method of the ecological purification island. According to the invention, the problem of stably purifying a tidal river channel is solved, an unpowered sequencing batch operation mode during operation is formed, a small amount of water pump electricity is required to be provided only during sludge discharge and backflushing, and meanwhile, clean water stored in the clean water section can be used for realizing backflushing on the purification filler in the ecological purification section, so that the system is energy-saving and environment-friendly.
本发明提供了一种感潮河道生态净化岛，包括沿生态净化岛长度方向依次连通的清水段、整流段、生态净化段和出水段，清水段包括单向流入口以及由下向上依次设置的沉沙区和沉淀区；整流段包括布水洞；生态净化段包括沿生态净化岛长度方向依次设置的进水布水墙、进水端填料保护层、净化填料、出水端填料保护层和出水花墙；出水段包括单向流出口；本发明还提供了一种前述的生态净化岛的反冲和排泥方法。本发明解决了稳定净化感潮河道的问题，形成运行期间无动力序批式运行模式，其仅在排泥及反冲期间需要提供少量水泵用电，同时可以利用清水段内储存的清水对生态净化段内的净化填料实现反冲，节能环保。
