2) The water taking system is applied to a multi-element riverbed structure, has stronger adaptability and more obvious improvement on water quality. The multi-element riverbed structure is the stratum which forms the riverbed, and has the conditions of a water-bearing layer (one or more layers) and a soil layer (one or more layers).
