Abstract

PURPOSE: To enhance the removal rate of pollutants and purification efficiency by avoiding blockade by burying an upper-opened impermeable tank in the ground, leaking out sewage in the unsaturated state from the bottom of the impermeable tank, and treating.
CONSTITUTION: An upper-opened box-type impermeable tank 1 made of concrete, rubber, etc. is buried in the ground. The sewage introduced into ceramic tubes 5, leaks out through gaps and holes into gravels 6 and is spread out on all side. Part of the sewage is vaporized above the surface GL by a capillary action, the remaining part permeates into the gravel layer 6, but is stored temporarily in the impermeable tank 1 positioned under the gravel layer 6. The sewage leaks out through a small hole 1a into the soil, or by a capillary evaporation A or capillary siphon B action. Thus, the blockade due to anaerobic microorganism and accumulation of floating matters in a sand layer can be avoided and the purification efficiency can be enhanced.
