The present invention discloses a
water treatment device and a water purification
system, which improves the
water treatment effect; the
water treatment device includes a water treatment shell; the interior of the water treatment shell is sequentially provided with a
magnetization treatment device and a
hydrogen generation device made of magnetic shielding material from the inside to the outside, and the
hydrogen generation device is arranged around the outside of the
magnetization treatment device; a water inlet and a water outlet are provided on the water treatment shell, the water inlet is connected to the
magnetization treatment device, the water outlet is connected to the
hydrogen generation device, and the magnetization treatment device is connected to the hydrogen generation device. By sleeve-arranging the hydrogen generation device between the magnetization treatment device and the water treatment shell, the effect of preventing the
magnetic field of the magnetization treatment device from leaking out is achieved, thereby enhancing the
magnetic field strength, thereby increasing the orderliness of water molecules, improving the
diffusion efficiency of water molecules, promoting the reaction of water molecules in the hydrogen generation device, so that the
hydrogen content and magnetization effect of the
treated water are effectively improved, and the
treatment effect of the water treatment device is improved.
