<p>PURPOSE:To prevent odor from generation by allowing waste water to be circulated for accelerating cleaning using a structure wherein an aeration tube is installed above protruded members which are provided on the bottom of the separation chamber in the cleaner unit for waste water aeration treatment. CONSTITUTION:Waste water cleaning tank consists of the separation chamber 1, aeration chamber 2, and sedimentation tank 6. The aeration chamber 2 and sedimentation tank 6 are connected through the partition plate 10 whose bottom is open to both of two. The separation chamber 1 has protruded members 8 at the bottom. The aeration chamber 2 has the aeration tube 4. The separation chamber 1 has the aeration tube 9 above the protruded members 8. The chamber 1 allows solid material in waste water to be settled for separation and stacked sludge to be held by the members 8, stopping its movement or vibration by circulatting water. Stacked sludge is decomposed by anaerobic microbes. The circulating waste water is decomposed by oxidation using aerobic microbes and, after aeration, is discharged from the pipe 5.</p> |
