を肥料として利用することも試みられている。BACKGROUND OF THE INVENTION Organic sludge discharged from various places as industrial waste is generated when organic wastewater is purified by an activated sludge method in various factories, sewage treatment plants, or human waste treatment plants. The excess sludge produced as a by-product in the purification of wastewater was conventionally landfilled or incinerated.Since this organic sludge contains nitrogen and phosphoric acid that can be used as fertilizers, it has recently been tried to use it as fertilizer. ing.

固化させた後、成形、乾燥することにより、肥料として
利用されていた。The sludge produced from the activated sludge method generally takes the form of a slurry or cake containing about 60 to 80% of water after passing through a dehydrator, and such sludge is dried after molding or as a flocculant. It was used as a fertilizer by solidifying it using lime or a polymer flocculant, and then molding and drying it.

めに畑を荒らすという問題があった。However, the fertilizers produced as described above all retain the strong unpleasant odor generated by the sludge itself, and not only give a great deal of dislike to the person who handles it, but in some cases Residents near the area where they are handled suffered from unpleasant odors, and fertilizers made from lime-solidified sludge also had the problem of devastating fields due to their strong alkalinity.
そこで、有機汚泥から造られた肥料が耐え難い悪臭を発

するのに大きな障害となっていた。Therefore, in order to solve the problem that the fertilizer made from organic sludge gives off an unbearable foul odor, it was also proposed to mix Otaniishi powder with the sludge to make the sludge an odorless fertilizer. Even with fertilizers, the original bad odor of sludge still remains strong, and the bad odor has hitherto been a major obstacle to utilizing sludge as fertilizer.

On the other hand, when the ratio is less than 2.5: 25, the deodorizing effect of the modifier becomes insufficient, and a satisfactory odorless fertilizer cannot be obtained, while the content of sulfate group or activated carbon in the modifier is insufficient. However, if the amount exceeds 5% or 10%, respectively, based on the dry weight, or if the blending ratio of the modifier to organic pollution is greater than 10: 7, based on the dry weight, the amount of sulfate radicals increases. In the present invention, it is included in the modifier because it becomes too acidic and tends to be strongly acidic, or the proportion of the fertilizing component becomes relatively small, making it unsuitable as a fertilizer, or economically disadvantageous. The amount of sulfate and activated carbon are Together provided for in earthenware pots, modifier: a proportion that is based on the dry weight of the organic sludge 2.5: 2
