Abstract
PURPOSE: To considerably lower the COD and chromaticity components of concd. org. waste liquid by adding a metallic ion dissociating material and H2O and/or O3 to the outflow slurry produced after biological treatment of said waste liquid then chemically treating the separated water.
CONSTITUTION: Fresh night soil 1 is flowed without being diluted into an arbitrary biological treatment device 2 of a biological nitrification and dentrification method, an activated sludge method, etc., and the mixed slurries of an outflow slurry 6 and concd. separated water 5 are introduced into a chemical mixing tank 7, when a chemical 12 is added. The mixed slurries from the tank 7 are separated to dehydrate cake 9 and dehydrated separated water 10 by a mechanical dehydrator 8. After the dehydrated water 10 is agitated with an agitating tank 10', it is neutralized by an alkali 13 consisting of a magnesium base alkali agent and/or calcium carbonate. Thence, it is flowed into a sedimentation basin 11, is separated of the precipitate 15 consisting of the depositioned ferric hydroxide and the like and is released as treated water 14.
