Underground water artificial recharge blocking control method
The invention is applicable to the technical field of underground water treatment, and provides an underground water artificial recharge blockage control method, an outer well casing and an inner well casing of an annular recharge well are both higher than the ground, and an infiltration medium layer with water quality filtering and blockage control functions is filled between the inner well casing and the outer well casing. The recharge water reaches the water-containing layer through the filtering medium layer, the blocking position is controlled by controlling the particle size structure of the filtering medium layer, the blocking treatment time is shortened, the economic cost is reduced, and therefore the purposes of continuous and efficient recharge and water quality filtering of the recharge water can be achieved. In addition, the problems of filter medium particulate matters and gas blockage between the outer well casing and the inner well casing are solved by utilizing the inner well to carry out back-raising backwashing and exhausting; long-term operation is achieved by replacing media, the service life of a recharge system is prolonged, and recharge is effectively promoted.
本发明适用于地下水治理技术领域，提供了一种地下水人工回灌堵塞控制方法，本发明中环状回灌井的外井井管和内井井管均高出地面，且内井井管和外井井管间填充有水质过滤和堵塞控制功能的入渗介质层，回灌水经过滤介质层到达含水层，通过控制过滤介质层的粒径结构来控制堵塞发生位置，降低堵塞处理时间和经济成本，从而达到持续高效回灌并且还能过滤回灌水水质的目的；并且针对发生在外井井管和内井井管之间过滤介质颗粒物和气体堵塞的情况，利用内井进行回扬反冲洗和排气解决；通过对介质的更换实现长期运行，延长回灌系统的寿命，有效促进回灌。
