TREATMENT OF NIGHT SOIL FOR PURPOSE OF INCREASING MARINE PRODUCT AND ATTACHMENT THEREFOR

摘要

PURPOSE:To subject night soil to decomposition with microbes, to separate it into solid matter and liquid, to change the solid matter into compost useful as an agricultural fertilizer, to clarify the liquid by further decomposition with microbes and to change the clarified liquid into a fertilizer for increasing marine products. CONSTITUTION:Dipped-up collected night soil is landed and reserved in a reservoir 1 at a decomposing base moored on the sea, affected by decomposition with microbes from a microbe tank 12 in a decomposing vessel 4, and then separated into solid matter and liquid in a precipitating vessel 5. After being dehydrated with a dehydrator 6, the solid matter is fermented in a fermenting vat 8 and turned into compost or feed. The liquid part separated by the vessel 5 is temporarily reserved in a decomposed liquid reservoir 10, transferred to the decomposing vessel 16 of an ocean-disposal ship A, matured by decomposition with microbes on the way while the ship is travelling toward a sea area for disposal, and then disposed to the ocean when it comes to the optimum matured state for increasing marine products.
