<p>PURPOSE:To efficiently treat waste water, by providing an area where a suspensible org. substance can be stagnated for a long time before waste water containing the suspensible org. substance is introduced into an anerobic bioreactor. CONSTITUTION:Waste water is introduced into the lower part of a suspensible org. substance stagnation part 2 from a waste water introducing pipe 6 and the suspensible substance is separated by the action of a barrier plate 3 to be stagnated in the lower part of the stagnation part 2 and contacted with a liquid containing anaerobic bacteria recirculated through the passage 8 between a partition plate 4 and the wall of the stagnation part 2 and fluidized to be solubilized. An org. acid formed is dissolved in waste water to be introduced into an anaerobic reactor 1 from the upper part of the stagnation part 2 through a guide part 5 and undergoes methane fermentation to be decomposed mainly into methane gas and carbon dioxide. By this method, the treatment of waste water containing the suspensible org. sustance is enabled.</p> |
