| 摘要 |
The invention relates to a water sanitising plant (100) that includes an intensive sanitising unit (102) and an extensive sanitising unit (104), consisting of a laid filtration zone. The intensive sanitising unit (102) is supplied with water to be sanitised and discharges the water thus pre-sanitised to the extensive sanitising unit (104). The sanitising installation (100) is characterised in that the laying zone (104) is a horizontal filtration zone consisting of a trench (122) having a slope descending from the area where the water from the intensive sanitising unit (102) is discharged, and in that it comprises an evacuation line (116) arranged at the end of the laying region (104) opposing the end just below the surface of the laid region (104), where the water from the sanitising unit (102) is discharged. |
