Abstract
PURPOSE: To enable to carry out washing sufficiently, in a process for washing off the screenings recovered from a sewage treatment plant, by washing the screenings again when the washing is insufficient by one washing.
CONSTITUTION: Said screenings is supplied in a washing tank 1 by a charging conveyor 2 or the like as well as washing water is supplied therein and stirred and washed by a stirring and washing machine 3. The washed screenings is scraped up by a dust removing machine 4 and conveyed out from the tank by a discharge conveyor machine 5. When the washing of the screenings is insufficient, after said screenings is dehydrated by a dehydrator, the discharge conveyor machine 5 is reversely operated to supply and transfer said screenings in a conveyor trough 9 and again thrown in the washing tank 1. After the screenings is again washed, it is scraped up by the dust removing machine. As described above, a washing time can be selected corresponding to a contamination degree of the screenings and repeating washing is carried out for a definite time.
