20100276349 | Integrated Orbal Oxidation Ditch - The integrated Orbal oxidation ditch, pertaining to water treatment technical field, comprises several ellipse oxidation ditches whose central island position is arranged with two or more round areas. Wherein, two round areas are tangential to or share the wall with the inner wall of the neighbouring oxidation ditch. The process water of various areas is connected with each other. Taking full advantage of the central island position of the traditional Orbal oxidation ditch, present practical and new invention introduces deposition area or deposition area and anaerobic area as well as inner/outer re-circulation zone, making the overall equipment layout of the oxidation ditch be more harmonious and reasonable, space use rate be high, area occupied be less and civil work expenses be lower. In particular, more than two deposition areas are arranged, increasing the flexibility of equipment use, meeting the variation requirements for water flow and water quality, strengthening technical suitability, integrating aesthetics and practicality as well as being convenient for use. | 11-04-2010 |
