Summary: | The utility model discloses a concentration and impurity removal device for salt lake adsorption and desorption qualified liquid. Comprising an analysis qualified liquid storage tank, a first-stage reverse osmosis membrane system, a first-stage nanofiltration membrane system, a high-pressure reverse osmosis membrane system, a second-stage nanofiltration membrane system, a third-stage nanofiltration membrane system, a third-stage nanofiltration water production tank, a fourth-stage dialysis nanofiltration system, a second-stage reverse osmosis membrane system, a concentrated water tank and a desalted water storage tank. According to the utility model, the reverse osmosis membrane and the nanofiltration membrane are combined in a crossed manner by utilizing different performances of the membranes, so that the qualified salt lake analysis liquid can be concentrated, and calcium and magnesium can be removed. By means of the cross combination mode, lithium ions can be concentrated to the required concentration, th |
