Embodiment Construction
[0027] In the present invention, the method of combining an upflow coarse filter bed, a vertical flow ecological filter bed and a sludge drying filter bed is used to treat and reuse eutrophic water bodies, such as figure 1 As shown, firstly, the eutrophic water body to be treated is sent into the upflow coarse filter bed by the pumping pipeline, and the eutrophic water body to be treated entering the upflow coarse filter bed is under pressure, and the upflow coarse filter bed from Suspended solids and algae substances are physically filtered and removed layer by layer from bottom to top, and the water treated by the upflow coarse filter bed is evenly distributed to the vertical flow ecological filter bed through the water distribution system, and the vertical flow ecological filter bed is used for secondary filtration. Biochemical treatment, effluent recycling; In addition, the deposited sludge in the upflow coarse filter bed is discharged into the sludge drying filter bed for ...
