The present invention relates to a water purification system with multistage waterfall plates comprising: a tank; a raw water inlet pipe composed vertically in the middle of the lower end of the tank to supply raw water upward; a water purification device including a raw water dispersing cap, which has a cap structure with an inner diameter greater than the raw water inlet pipe to envelop the upper part of the raw water inlet pipe, and is opened along the edge of a lower part while separated from the enveloped upper part of the raw water inlet pipe to spray the raw water downward, and multistage waterfall plates, which are arranged in layers around the raw water dispersing cap, have a conic structure getting wider downward and are composed at the lower part of the raw water dispersing cap to drop the raw water in multiple stages; and a purified water outlet pipe connected to the middle of the lower end of the tank to supply purified water to a user and penetrated in the middle inside by the raw water inlet pipe. Therefore, the present invention purifies raw water by dropping the raw water in multiple stages as a contact area between the raw water and air is increased and thus the amount of dissolved oxygen is increased while harmful materials included in the raw water are separated. In addition, the purified water stored in the tank is discharged to the middle of the tank when the purified water is supplied to a user, thus the purified water is not congested but evenly discharged, and the present invention has a simple composition, thus is easy to maintain and manage. |
