摘要:The anti-filtration recharge well is the most important part of the groundwater recharge project. It is generally composed of a recharge well and a recharge pool. The main problems of the existing anti-filtration recharge well are low recharge capacity and blockage. In this paper, the structure of recharge pool is improved and optimized, and a new square dual anti-filtration recharge well is designed, the laboratory steady flow recharge tests were performed. The conclusions are as follows: (1) Under the same test conditions, the recharge volume of ordinary recharge well, existing anti-filtration recharge well, new square dual anti-filtration recharge well were 7.75, 1.05, 4.64 L/min, respectively. The recharge volume of square dual anti-filtration recharge well is about 60% that of the ordinary recharge well. (2) Compare to the existing anti-filtration recharge well, the recharge volume of square dual anti-filtration recharge well is increased by about 440%. (3) During the repeated laboratory recharge tests of the square dual anti-filtration recharge well, the largest single well recharge volume was appeared in the first time. With the increase of recharge test times, the single-well recharge volume gradually decreased and tended to be stable.
