| 摘要 |
<p>The invention relates to a process for treating waste water (Ww) comprising organic material, wherein waste water (Ww) originates from a food industry plant, such as from a slaughterhouse or a dairy, the process comprising a step for feeding waste water (Ww) to a first purification phase, such as to a drum screen (2), for separating the coarsest solid debris from waste water (Ww), a step for feeding waste water (Ww) from the first purification phase to a second purification phase, a step for floating waste water (Ww) in a second purification phase, such as in a flotation unit (4), for removing solid debris and flocculated matter from waste water (Ww), a step for feeding waste water (Ww) from the second purification phase to a discharge outlet (56), and a step for discharging purified water through the discharge outlet (56). Waste water (Ww) is fed from the second purification phase to the discharge outlet (56) via an additional purification phase for filtering waste water (Ww) with a filter (53) comprising filter mass grains.</p> |
