The parts having the same functions as those shown in FIG. 1 are designated by the same reference numerals. In FIG. 1, a raw sludge 1, human waste, and a concentrated sludge 13 obtained by concentrating an organic sludge 10 generated from a septic tank sludge treatment system are supplied to a self-heating stirring tank 18 and mechanically stirred with an oxygen-containing gas 3. Aerate for 3 to 4 days. When the temperature of the feedstock is 20 ° C., the internal temperature of the stirring tank 18 is 60 to 70 due to the heat of biooxidation generated when the organic matter is mineralized without external heating using fuel such as petroleum. ℃
, So that a temperature rise of 40 to 50 ° C will occur 1
The conditions for supplying the organic sludge 10 and the stirring time are set.

Since the exhaust gas 19 containing ammonia is discharged from the stirring tank 18, this is blown into the biological nitrification and denitrification treatment device 9 of the human waste and the septic tank sludge 10 to dissolve the ammonia in water to biologically nitrify and denitrify. To process.

工事を施工しておくことが好ましい。The self-heating stirring tank 18 is preferably a multi-stage series tank of 3 to 4 tanks instead of one tank in order to prevent a short pass. Air is sufficient as the oxygen-containing gas 3 to be used for aeration, but oxygen-enriched air or pure oxygen that can reduce the amount of exhaust gas and exhaust heat may be used. In order to reduce the heat radiation from the self-heating stirring tank 18 as much as possible, it is preferable to carry out heat insulation work.

ましい。These sludges are supplied to the self-heating stirring tank 18 described above. The supplied sludge is concentrated to increase the sludge concentration. That is, the excess activated sludge 17 is not directly supplied to the self-heated stirring tank 18, but the polymer coagulant 11 is added as in the case of FIG. 2 and concentrated by the screen 12 or the multi-disk dehydrator, After concentrating by a mechanical means such as a centrifugal concentrator or flotation, concentrated sludge 13 having a solid content concentration of preferably increased to 3% or more is supplied to a self-heating stirring tank 18. Excess activated sludge 17, septic tank sludge 1
Since it is difficult to concentrate 0 into a high concentration by the weight precipitation concentration method, it is preferable to apply the mechanical concentration means as described above.

Dewatering is performed by the mechanical dehydrator 6 to obtain a low-moisture dehydrated cake 7 having a water content of 60% or less.

てしまい、植物のリン利用率が悪い。In the process of the high temperature bio-oxidative stirring process of the present invention, the pathogenic bacteria in the sludge are completely killed, and the organic matter which is easily decomposed is completely decomposed in the process of high temperature oxidation. It is a compost product that can be applied as it is to farmland, has no bad odor, has a earthy odor, and is safe in terms of hygiene. In addition, when dewatering sludge, when an iron-based coagulant or a magnesium compound is added, phosphorus becomes iron phosphate or magnesium ammonium phosphate (MAP).
As a result, a fixed compost can be manufactured. When compost is applied to compost containing immobilized phosphorus, phosphorus does not elute due to rainfall, so that the phosphorus absorption effect on plants is improved. Since phosphorus contained in ordinary compost is not fixed, phosphorus is eluted by rainfall and the phosphorus utilization rate of plants is poor.

Nitrogen) and COD are removed. The water obtained by the membrane separation unit 22 in the biological nitrification / denitrification treatment device 9 is usually sterilized and discharged after the COD is highly removed by the advanced treatment device 15 using activated carbon or the like. Excess activated sludge 17 is generated from the biological nitrification and denitrification process of human waste, septic tank sludge 10 and dehydrated separated water 8. Therefore, the activated sludge 17 is concentrated by the screen concentrator 12 and then supplied to the self-heating stirring tank 18. And biodegrade.

The amount of compost production can be reduced without reducing the amount of raw garbage and sludge received. That is, in FIG. 1, the temperature at which bio-oxidation in the self-heating stirring tank 18 is high (6
The sludge is extracted at a high temperature by ozone oxidization, ultrasonic irradiation, oxidation with hypochlorous acid, oxidation with hydrogen peroxide, alkali treatment, mechanical grinding, etc. After the solubilization treatment, it is returned to the self-heating stirring tank 18. As a result, the solubilized sludge whose biodegradability is remarkably improved is subjected to biooxidation, mineralized, and disappears. The sludge solubilization effect of the physicochemical solubilization treatment improves as the temperature rises, but in the present invention, since the temperature can be raised without artificial heating, the physicochemical solubilization treatment under high temperature conditions is applied. There are important effects that can be achieved.
