A EQUIPMENT FOR NONPOINT POLLUTION SOURCE

摘要

A gap-adjustable screen is provided to construct the screen freely considering regional characteristics although the screen is fabricated in a plant by adjusting easily a gap of the screen, and an equipment for treating a nonpoint pollution source is provided to remove particles such as fine particles and dissolved particles as well as suspended particles at one time by one equipment through corresponding steps according to specific gravities, sizes and properties of the particles. An equipment for treating a nonpoint pollution source comprises: a settling tank(10) having an inflow pipe(11) formed on a side face thereof; a screen tank(20) which is formed to be connected to the settling tank, which has a first overflow hole(21) formed in its face contacted with the settling tank and a particle discharge hole(22) formed in its face opposite to the face that is contacted with the settling tank, and which has a screen(100) formed below the first overflow hole and the particle discharge hole; and a particle storage tank(30) which is connected to the screen tank, and in which particles discharged from the particle discharge hole is stored. The equipment further comprises: a pumping tank(40) communicated with the screen tank through an induction hole(23) formed in one face of the screen tank under the screen; and a detention tank(50) formed to be connected to the pumping tank, wherein the detention tank has a storage part(51) formed in a lower part thereof and communicated with the pumping tank, an adsorption layer(53) charged into an upper part of the storage tank, second overflow holes(52) formed in an upper portion of its face contacted with the pumping tank, and a treated water discharge pipe(55) that is in communication with the adsorption layer.
