摘要： PROBLEM TO BE SOLVED: To make easy a maintenance and administration for preventing a leakage from a gas tank, etc., and to reduce a generating amount of a surplus sludge by converting a high concn. solid matter-containing waste water into an org. acid by an acid fermentation, returning a sludge to the acid fermentation stage after a solid-liq. separation and treating a filtrate at a denitrification- denitration or a denitration-denitrification stage. SOLUTION: A raw water is supplied to an acid fermentation tank 1 from an inflow line 5 and converted into the org. acid by subjecting the raw water to hydrolysis/acid fermentation. Then the acid is subjected to the solid-liq. separation at a solid-liq. separator, and a digested sludge is returned to the acid fermentation tank 1 with an acid fermentation sludge return line 6. A separated liq. is treated at a denitrificating tank 3 and a nitrating tank 4 to remove a nitrogen compd. A denitrificated/nitrated sludge is separated with the solid-liq. separator and returned to the denitirificating tank 3 by interposing a nitrated/denitrificated sludge return line 7. A treated water removed the nitrogen compd. is discharged from a treated liq. discharge line 8.

摘要： PURPOSE:To promote the self weight increasing of sludge not only in an aerobic state but in an anaerobic state and effectively execute treatment of waste water by adding a sulfur component to the waste water in the waste water treating device for self-granulation of the sludge. CONSTITUTION:The waste water 6 is supplied to the top of an oxygen dissolving vessel 4 and is brought into contact with oxygen or air 8 supplied from the bottom thereof. The waste water in which the oxygen or air is dissolved and which is obtd. in this vessel is supplied by a charging pump 5 into the bottom of a reaction vessel 1 where a biological treatment is executed. The growth of Beggiatoa which is the top priority species among the microorganisms to cause the self-granulation of the sludge is activated to promote the self- granulation of the sludge by adding a sulfide (Na2S, etc.) 9 to the bottom of the reaction vessel 1 under an upward current condition. The water treated in this reaction vessel 1 is discharged outside the system as treated water 10 from the part in the upper part of the reaction vessel 1 through a buffer tank 2 and is partly returned as a circulating liquid 7 to the oxygen dissolving vessel 4 by a pump 3.
