Because it contains 90% water, its disposal is extremely difficult. That is, incinerating these requires a complicated mechanism and a large amount of fuel oil, including evaporation of 4 to 9 times as much water as combustible materials and secondary combustion to prevent generation of bad odors due to incomplete combustion. In addition, when making fertilizer by the fermentation method, excess moisture makes it impossible for air to circulate, resulting in extremely bad odors due to anaerobic fermentation and stagnation of fermentation. Methods are used to reduce the moisture content by addition and circulation of the dried product. However, all of these methods are extremely expensive and are not economically viable as waste disposal methods. Furthermore, landfill disposal is already at a standstill due to the generation of foul odors and the shortage of landfill sites.

用できたものである。(Means for Solving the Problems) The present invention solves the above-mentioned current situation by solving PJ? This method provides a means to effectively treat organic sludge containing a large amount of water using current methods. In other words, the inventor found that when a very small amount of cut waste paper is added to this sludge and air is allowed to flow through it, the organic water-containing sludge undergoes good aerobic fermentation even under excessive water content, and is almost odorless. Organic matter in sludge is decomposed. Furthermore, during aerobic fermentation, the sludge itself generates heat and reaches a high temperature, and self-drying occurs in an odorless environment, so the fermented organic water-containing sludge can be easily incinerated and can also be used as organic fertilizer. It is something.

Good aerobic fermentation can be carried out even if the amount added is much smaller than the amount required for this purpose. Example 9, moisture content 85%
In order to adjust the water content of sludge to 60%, which is suitable for aerobic fermentation, approximately 45% by weight of waste paper (assuming a water content of 5%) is required, and even though it is waste paper, the cost is excessive. Moreover, the amount of waste paper is about three times the amount of dried sludge, diluting the active ingredients as fertilizer and significantly reducing the value of the fertilizer. However, in implementing this, the inventor discovered that the purpose could be fully achieved with an amount of waste paper that was less than about 10% of the amount considered necessary. The moisture content at this time is about 82%, which is far from the appropriate moisture content of 60% for aerobic fermentation. Nevertheless, the reason why good aerobic fermentation occurs is that 4% of the weight of the sludge is made of waste paper (width: 3 m, length: 5-3 m).
Since the natural volume of 5rIn) is about four times the sludge volume, these mixtures have a form in which paper is interposed between the sludge, and the sludge can come into contact with air through the voids held by the paper's elasticity. Therefore, aerobic fermentation is easily maintained despite excessive water content.

A mixture of ikg was sent to 1 m' (520 kg J) four times (4 m' / 2100 kg) during 8 hours during the day, and during this period, ventilation was carried out from the bottom to 4 rT? The switching mechanism was moved backwards four times, and ventilation was continued for 1012 hours.

らかマある。As shown in the examples above, according to the method of the present invention, even organic sludge with a high moisture content, which is normally impossible to undergo aerobic fermentation, can be fermented in a good manner by adding a few percent of waste paper and aerating it. Aerial fermentation occurs, exothermic drying occurs without malodor, and the product is easily combustible and can be used as an organic fuel, but there are obvious limitations.

的な焼却及び肥料化が可能となる。Therefore, according to the method of the present invention, by simply mixing a few percent of used paper with dry organic sludge containing 4 to 9 times more water and aerating it, a lump of organic material that contains 172 to 1 times more water and can be easily combusted can be produced. If this sludge is accumulated for a certain period of time and allowed to mature, it can be turned into organic fertilizer. Therefore, it is possible to incinerate and turn this organic water-containing sludge into fertilizer very economically.

できる。Furthermore, among the various organic sludges mentioned above, sewage and deep-bed sludge contain various heavy metals and may not comply with legal regulations, and are not necessarily suitable for fertilizer production. By using the combustion heat of this food sludge, which is highly evaluated as a raw material for 8i-rich fertilizers, to dry food sludge, a highly valuable additive-free dry bacterial fertilizer can be produced at a low cost. You can also do that.
