题    目： A novel shortcut nitrogen removal process using an algal-bacterial

                consortium in a photo-sequencing batch reactor

时    间： 2016年4月6日（星期三）上午9:00-11:00

地    点： 科研楼312室

报告内容摘要： Treatment and discharge of high ammonia strength wastewater, such as industrial wastewater, centrate from anaerobic digestion of domestic, industrial and agricultural wastes and landfill leachate, result in serious environmental problems due to the toxicity of free ammonia to aquatic life. This study investigated a hybrid microalgal photosynthesis/shortcut nitrogen removal process in a photo-sequencing batch reactor (PSBR) with alternating light and dark periods. In this process, microalgal photosynthesis provides oxygen for nitritation during the light period. With addition of an organic carbon source during the dark period, the reactor removed over 90% total nitrogen (TN) without aeration other than mixing. The high concentrations of ammonia and nitrite and low dissolved oxygen concentration in the PSBR effectively inhibited nitrite oxidizing bacteria, resulting in stable nitritation. Additional experiments were carried out with anammox bacteria integrated into the system, which eliminated the need for organic carbon addition.
