<p>PROBLEM TO BE SOLVED: To provide a compost producing apparatus capable of constituting a treating tank of any size by constructing a compost treating tank by combining panels and capable of promoting compost fermentation by supplying a microorganism and air even from the wall part of the treating tank. SOLUTION: A compost treating tank 1 is constituted by combining panels 10 and the panels are composed of a porous concrete. Pores formed on the concrete are provided with microorganisms and a nutrient source for the microorganisms and the panels have air permeability. In the compost treating tank obtained by combining the panels, a great number of porous pipes are stood in the interior and a large amount of air is supplied from the inside and the outside of a compost material so that the proliferation of useful microorganisms are promoted and emission of an offensive smell can be prevented.</p> |
