高脱氮效能厌氧氨氧化反应器颗粒污泥特性及控制
Characteristics and Control of Granular Sludge in a High-rate ANAMMOX Reactor
摘要
Abstract
The causes of the granular sludge loss and the reinforcement of particle sludge settling property by different strategies were studied by introducing the anaerobic ammonium oxidation (ANAMMOX) sludge in the anaerobic reactor. The results show that, when the nitrogen removal reaches 3.2 kg×m-3×d-1, the granular sludge mass loss increases with gas production. The ideal improvement of granular sludge settling can not be gotten by using the way of crush, reflux and reform new granular sludge. For granular sludges having the same diameter, the MLVSS/MLSS (mixed liquor volatile susperded solids/ mixed liquor suspended solids) of the granular sludge in the reactor is less than that of washout granular sludge. The CaSO4 particles added could be used as the new granular nucleus by the granular sludge of washout. After culturing for 48 days, the granular sludge settling is improved, and the nitrogen removel rate increases from 5.23 kg×m-3×d-1 to 9.2 kg×m-3×d-1. In addition, it was found that, when the total nitrogen concentration is up to 1320 mg×L-1 in the influent, the activity of the ANAMMOX granular sludge doesn¢t be affected. It suggests that the ANAMMOX granular sludge has strong tolerance to total nitrogen.关键词
