<p>PROBLEM TO BE SOLVED: To execute decomposition, reduction of a volume, and extinction treatments in a short time at a high bio-treating efficiency without using a large treating tank by a method wherein thermophilic ray fungi are used as a raw sludge-treating microorganism, and that together with a raw sludge is treated under an atmosphere at a specific temperature. SOLUTION: A raw sludge is charged into a crusher 23 from a hopper 34 to be crushed into small pieces, which are supplied into a bio-treating tank 12 in which an organic material decomposing microorganism as a raw sludge treating microorganism together with a culture material is charged. As the organic material decomposing material, a fungus group wherein a thermophilic actinomycete, a thermophilic fiber decomposing fungus, and a photosynthetic fungus are mixed, is used. Then, the mixture is treated by rotation of a stirring blade 42, sprinkling water from a water spray pipe 51, and heating with a heater 54 to keep the inside of the bio-treating tank 12 under a temperature atmosphere at 70 to 90 deg.C. Thereby, a large treating tank is not required, and the bio-treatment can be executed at a high efficiency in a short time.</p> |
