Abstract
PURPOSE: To remove impurities in sewage efficiently by adding an oxidizing agent and a metallic ion dissociating material to mixed slurries of treated water and excess sludge of a biological nitrifying and denitrifying process, causing these to react under acidic conditions then concentrating and dehydrating the same.
CONSTITUTION: An oxidizing agent 8 such as hydrogen peroxide and a metallic ion dissociating material 9 are added to mixed slurries 7 of the outflow slurry 6 from a biological nitrifying and denitrifying process 2 and separated water 5 from excess sludge, and these are stirred for a prescribed time in a reaction vessel 10 in acidic conditions of 3W4pH. This reaction liquid is neutralized in accordance with need, and is separated to concd. sludge 13 and concd. separated water 12 in a concentrating vessel 11, after which powder active carbon 18 is added to the water 12 and the powder active carbon is separated in a sedimentation basin 21. The sludge 13 is conducted to a dehydrating process 14, where it is separated to separated water 15 and dehydrated cake 16. This is mixed with the supernatant 22 in the basin 21 and is subjected to subsequent treatments.
