<p>PURPOSE:To provide a method for treatment of org. sewage which efficiently treats the org. sewage with a simple treatment. CONSTITUTION:The high-concn. org. sewage subjected to sepn. of solid from liquid is introduced into a solubilizing vessel 1 where the org. sewage is made into lower molecule matter by org. nutrient bacteria and is inoculated with photosynthesis bacterium seed bacterial 3. The BOD materials made into the lower molecule matter are thus metabolized and removed. The sewage is then transferred into a photosynthesis bacterium vessel 4 where fine wooden pieces 5 are settled at about 15cm thickness on the front surface and are ventilated from the lower part of the vessel. The photosynthesis bacteria are propagated by the fine wooden pieces 5 while the low-molecular org. materials are subjected to a metaborization treatment. The treated water is thereafter transferred into a contact oxidation vessel 6 while the outflow of the photosynthesis bacteria is prevented by the fine wooden pieces 5. The activity of microorganisms, etc., by food chain is promoted by the contact materials stuck with the bacteria and the water is purified while the generation of the sludge is prevented.</p> |
