Rough sieving and presedimentation of the waste water take place in a prim. treatment unit, and the water is then fed to a dam in which solid particles are removed through a filter arranged along the dam sides and/or bottom. The uncleaned waste water is fed to the dam in batches at an ambient temp. below 0 deg.C., so that it is frozen through. Cleaned water is fed away from the dam at an ambient temp. of over 0 deg.C.. - The cleaned water is fed to a distribution system which extends over a plant cultivation area where it serves as feed water, being made to pass through a diffusion deposit in which a final sedimentation can be carried out. The slurry sepd. in the prim. treatment unit, in the dam and possible in the diffusion deposit is fed to a processsing unit where it is broken down by composting, pref. with the aid of natural earth organisms, e.g. worms. The process unit is maintained damp by watering, and leak water from it is fed back to the diffusion deposit and/or dam. |
