Alternate replacement type recharge system
The invention discloses an alternate replacement type recharge system. The alternate replacement type recharge system comprises a ditch, a plurality of recharge wells and an extraction device, whereinthe ditch is used as a flow path of a replenishment water source; the multiple recharge wells are independently arranged, the recharge wells are communicated with the ditch, and filter layers are arranged in the recharge wells; and the extraction device is communicated with the recharge wells. The alternate replacement type recharge system is suitable for the conditions that an aquitard is distributed on the ground surface and a continuous sand layer is distributed on the lower portion, water is introduced into the sand layer through the recharge system, the infiltration efficiency is guaranteed, meanwhile, the problems that a traditional out-of-wall filtering device is difficult to clean after being blocked and the recharge efficiency is influenced are solved through alternate replacement type recharge and regular backwashing, and efficient and long-term operation of the recharge wells is guaranteed while the available quantity of underground water resources is increased. Infiltration efficiency is effectively guaranteed, blockage is relieved, practicability is high, uninterrupted recharge can be achieved, recharge efficiency is guaranteed, the construction cost is low, and the system is suitable for wide popularization.
本发明公开了一种轮休更替式回灌系统包括沟渠、回灌井和抽取装置，其中沟渠用于作为补给水源的流动路径；回灌井设有若干个、且各回灌井相互独立设置，回灌井与沟渠连通，回灌井内设有过滤层；抽取装置与回灌井连通。本发明提供的一种轮休更替式回灌系统适用于地表有弱透水层分布，下部有连续砂层分布时的情况，通过回灌系统将水引入砂层，保证入渗效率，同时轮休更替回灌以及定期的反冲洗克服了传统壁外过滤装置淤塞后清洗困难、影响回灌效率的问题，在增加地下水资源可利用量的同时也确保了回灌井高效且长期地运行。本发明有效保障入渗效率，减缓堵塞发生，实用性强，可以实现不间断回灌，保证回灌效率且工程造价低，适于广泛推广。
