The invention discloses an electrochemical
water treatment device with an
electrode spacing regulation and
control function. The device comprises a
pool body with opening on the upper and lower surfaces, wherein the
pool body is made of an insulating material, a water inlet
pipe is arranged on one side of the
pool body, a water outlet
pipe is arranged on the other side of the pool body, a fixed
electrode is arranged in the pool body, a first
electrode of an annular structure is arranged in the pool body, a first telescopic rod made of an insulating material is arranged above the pool body, thefirst telescopic rod penetrates through the first electrode, and a plurality of second telescopic rods connected with the first telescopic rod are arranged on the periphery of the first telescopic rod. According to the invention, different numbers of electrodes can be selected for participation according to different
water treatment capacities while the water inlet rate is adaptively adjusted, and the
rate difference between the water inlet
pipe and the water outlet pipe is offset through the rotating conical rod, so that the
water storage capacity in the pool body is improved, and the adsorption capacity of
calcium,
magnesium and
sodium ions in unit time is improved; and when a small amount of water needs to be treated, the electrode area participating in
water treatment can be reduced,so that the participation amount of the first electrode and the second electrode is reduced, and the service life is prolonged.
