<p>PURPOSE:To increase the multiplication of bacteria in oxidizing beds and in deodorizing chamber so as to accelerate the oxidation of human waste and to decrease the accumulation of ppt., by spreading sewage, which has been deodorized by passing through plane oxidizing beds, to the sewage-reserving chamber. CONSTITUTION:Sewage enters through an inlet 1 to a semispheric sewage reservoir 4, then passes charcoal 8 goes, through a path under the bottom of a weir 7, and overflows an oxidizing bed 9, then enters in a deodorizing chamber 6. These processes are repeated many times, finally the sewage enters a pump chamber 11. Then the sewage is returned by a manual pump 12 for returning sewage through a returning pipe line 13, and is spread through a spreading pipe 14 installed over the inlet 1, hereby oxidized sewage in mixed with the human waste in the semispheric sewage reservoir 14. Because about 90% to returned sewage has been oxidized, the sewage contained in the reservoir 4 is quickly oxidized. In addition, the sewage flows smoothly through the disposig tank without accumulation of ppt. because of the returned sewage.</p> |
