A treatment device of precipitation water is provided to form a jet nozzle for jetting water and compressed air into the lower inside of an outside container. An injection member(121) is formed at the upper side of an external box(160) supported by a supporter(161). The mixed sludge(201) mixed with sludge and waste water is injected into the injection member from the outside. One or more circular discharge holes(151) and discharge paths(152) are formed at the outer circumference of the external box so that the discharge waste water is discharged to the outside. A sludge discharge hole(162) is formed at the lower end of the external box and guides the precipitated sludge into a pressure tank(163). A lower projection hole(132) is formed at the inside of the injection member, projects water and compressed air into the lower inside wall of the external box and removes the solidified sludge. |
