Abstract
PURPOSE: To remove impurities in sewage efficiency by adding a focculant and an adsorbent to mixed slurries of the treated water and excess sludge of a biological nitrifying and denitrifying process, and separaing these to concd. sludge and separaed water in a concentrating process.
CONSTITUTION: Mixed slurries 7 of the outflow slurry 6 from a bilogical nitrifying and denitrifying process 2 and separated water 5 from excess sludge are conducted to a catalytic vessel 10, where powder active carbon 8 is added thereto and the slurries are agitated catalytically, after which it is added with a flocculant 9 contg. an inorg. flocculant, whereby flocculation reaction is caused. The outflow liquid from the vessel 10 is separated to concd. sludge and concd. separated water 12 in a concentrating vessel 11. The water 12 goes through a sand filter tower 1 and is treated in a granular active carbon tower 21, from which it is discharged as high concn. treaed water 22. The sludge 13 is conducted to a mechanical dehydrating process 14, where it is separated to dehydrated and separated water 15 and dehydrated cake 16. If necessary, the water 15 is mixed with the water 12, and is subjected to subsequent treatments.
