Sewage treatment device

Abstract

The invention discloses a sewage treatment device which comprises a box, wherein a second baffle is arranged at the top on the left side of an inner chamber of the box; a second water pipe is arranged on the left side of the top of the box; the second water pipe is penetrated through the top of the box; a first impurity outlet is formed at the top on the left side of the box; a second impurity outlet is formed at the bottom of the first impurity outlet; an accommodating box is arranged on the left side of the box; a second filtering screen is arranged in the inner chamber of the accommodating box; a third water pipe is penetrated through the box and a water collecting tank; and a clean water tank is arranged at the bottom on the right side of the box. In the sewage treatment device, an external water pipe is connected with the second water pipe; water and impurities are separated under the filtering effect of a third filtering screen; the impurities are discharged from the box under the effect of motion of brush; and the sewage treatment device not only changes the mode of directly draining the sewage after only filtering for one time, realizes the twice impurities separation and realizes complete filtering but also wastes no time.
