<p>PURPOSE:To increase the amt. of night soil to be treated and to execute a fermentation compositing treatment in a good state by recovering the sprayed night soil in a slurry state in a dehydration water storage tank in the bottom of fermentation tanks, evenly permeating air from the bottoms of the fermentation tanks and accelerating fermentation of the treated mixture by anaerobic fermentation. CONSTITUTION:Pipes 19 with blast holes 19a capable of permeating the air to the fermentation deposits, dehydrating channels 20 with through hole caps 20a in the lower parts of these pipes 19 with the blast holes 19 and the dehydration water storage tanks 14 communicating with the outside of the dehydrating channels 20 with through hole caps 20a rectangular and the parallelepiped fermentation tanks A, A' are installed to the bottoms of the rectangular parallelepiped fermentation tanks A, A'. The flowing down night soil in the slurry state is recovered from the dehydrating channels 20 with the through hole caps 20a into the dehydrated water storage tanks 14 and are sprayed again onto the compost raw materials to facilitate the fermentation.</p> |
