Abstract
PURPOSE: To use the plant even at a location where the quantity of water employed is limited by a method wherein sewage, such as night soil, etc. is aerated, the sewage is circulated and filtered twice or more while the water disposed is oxidized, dechlorinated and deodorized and returned to a raw tank and reutilized.
CONSTITUTION: Sewage from a raw tank 2 is forwarded to a septic tank 1 through a pipe 4, and solid matter is separated at a sedimentation chamber while a supernatant liquid is transmitted to the first filtration tank 31 through a sterilizing chamber 11. The large solid matter of the supernatant liquid is removed through a porous plate 32 at the tank 31, the liquid is sent to an aeration tank 39 through a pipe 36, and deposits among bodies disposed at the tank 39 are returned to the first filtration tank 31 by means of a pipe 38 and let pass through a filter medium 35. Meanwhile, the water disposed is forwarded to the second filtration tank 45 through a pipe 43, an oxidant 52 is added here, and a nitrogen component is removed. The water disposed is transmitted to the third filtration tank 53 through a pipe 51 and contacts with a dechlorinating agent at that time and is disposed while the water is deodorized and decolored through an adsorbing layer 55 of activated carbon, pH is adjusted, and the water is returned to the raw tank 2.
