Abstract

PURPOSE: To purify organic waste water with high efficiency, by adding hydrogen peroxide and ferrous ferric substances to outflow slurry from a biological treatment process, and post-treating the slurry as such or after mixed with an alkali.
CONSTITUTION: Untreated night soil 1, without being diluted, is subjected to a thorough treatment in a nitrifying liquid-circulating biological nitrification/denitrification device 2. Separated water 10 is mixed with outflow slurry 11 and introduced into a reservoir 12. The slurry in the reservoir 12 is agitated in an agitation vessel 13, where hydrogen peroxide 14 and a ferrous sulfate solution 15 are added, and then further agitated in another agitation vessel 16, where a ferric sulfate solution 17 is added. Thereafter, the slurry is neutralized in a neutralization vessel 18 by addition of an alkali 19 such as magnesium hydroxide, and separated into a dewatering effluent 21 and dewatered cake 22 by a filter press 20. The effluent 21 may be drained as such or after coagulation precipitation, filtration through sand or the like.
