Abstract

The invention discloses a ditch anti-blocking recharge filtering device, and belongs to the technical field of aquifer recharge, namely groundwater artificial recharge. The ditch anti-blocking recharge filtering device comprises a ditch, a labyrinth weir structure, a sloping plate filter structure and a dredging well, and the labyrinth weir structure is laid on a ditch slope, and comprises a plurality of labyrinth weir monomers; each labyrinth weir monomer comprises filter plates I and filter plates II, and the filter plates I and the filter plates II are each provided with a plurality of water inlets; the filter plates I, the filter plates II and the ditch slope enclose and form a water storage cavity, and the water storage cavity is vertically formed along the ditch slope; and one end ofthe sloping plate filter structure communicates with the labyrinth weir structure, and the end, far away from the labyrinth weir structure, of the sloping plate filter structure communicates with thedredging well through a collector pipe which is provided with a plurality of drain holes. According to the ditch anti-blocking recharge filtering device, the area of a river channel is not occupied,and water flow is not affected; and the filtering device is prevented from being blocked by sediments, and the filtering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of groundwater artificial recharge, in particular to a ditch anti-clogging recharge filter device. Background technique [0002] Managed Aquifer Recharge——Managed Aquifer Recharge, referred to as MAR, is a technical method for purposefully storing water in suitable aquifers, and adopts a series of management measures to ensure that human health and environmental safety are not damaged. Due to the improvement of the ecological environment, the problem of water resource shortage, especially seasonal water resource shortage, can be solved through mining to obtain considerable economic benefits. [0003] In solving the problem of artificial recharge, Chinese patent application CN201210003853 discloses a method for groundwater recharge and seepage enhancement, in which a recharge tank is artificially excavated on a high permeability soil layer, and the coarse filter material is filled in the recharge tank as reve...
