Abstract
The utility model relates to an enhanced type ecological marsh treating facility for treating sewage. Floats and settling suspensions in the sewage can be removed through a settling pool. The water body treated by the settling pool is uniformly distributed to a vertical flow filtering bed of a vertical flow and horizontal flow combined filtering bed through a water transporting and distributing system. The discharged water enters a horizontal flow filtering bed of the vertical flow and horizontal flow combined filtering bed through a water collecting pipeline. After the polluted water body is biochemically treated by the vertical flow filtering bed and the horizontal flow filtering bed, the water body enters a second-stage ecological marsh through the water collecting pipeline, and is purified and discharged into the natural water body. The sludge deposited in the settling pool is discharged into a sludge drying bed to be stabilized, and the percolate flows back to the settling pool to be treated again. By combining the settling pool, the vertical flow filtering bed, the horizontal flow filtering bed and the sludge drying bed, the polluted water body is treated, the polluted water body is effectively treated, and the sludge disposition problem is solved at low cost; the utility model is suitable for treating the rural living sewage, urban landscape water, river polluted water body and the like.
Description
Technical field
