Title: Purification of filthy water such as night soil
Inventor: SUZUKI TAKAYUKI
IPC: C02F3/30
Filed: 1981-11-19
Abstract: PURPOSE:To improve the precipitability and flocculability of active sludge and to reduce NaOH during flocculation, by adding an alkaline calcium compound to filthy water derived from night soil, biologically treating the filthy water, adding an acidic inorganic flocculant to it and then flocculating it. CONSTITUTION:Filthy water 1 derived from nightsoil together with returned sludge 2 and a circulating nitrified liquid 3 flows into the first denitrifying step 4 held under an anaerobic condition, so that NOx in the circulating nitrified liquid 3 is denitrified by denitrifying bacteria using BOD components in the filthy water 1 as a reducing agent. NH3 and residual BOD parts in the filthy water 1 flows into the next nitrifying step 5 to nitrify NH3 into NOx and to oxidize and remove the residual BOD. In the nitrifying step 5, an alkaline Ca compound 9 is added, and Ca<+> bonded with CO<2->3 and PO<3->4 in water is changed  into CaCO3 and calcium phosphate and included in the flocks of activated sludge. Consequently, flocks having large strength and specific gravity are formed.
