Plant, Season, and Microbial Controls on Complete Denitrification in Treatment Wetlands

摘要提案标题：植物，季节和微生物控制完全反硝化处理湿地首席研究员：奥托R。Stein机构：蒙大拿州立大学提案编号：1034434本项目的目的是确定在不同有机碳负荷率下，湿地植物种类和季节对人工湿地微宇宙去除硝酸盐的影响，以及根际微生物群落动态与反硝化气体排放组成之间的关系。研究的总体目标是最大限度地减少处理后的废水流出物和气体排放中的NO3和N20，并最大限度地增加处理湿地中反硝化过程中产生的N2量。 预计这项研究将产生有用的数据，植物物种和操作条件的最佳组合，用于人工湿地的城市污水三级处理。该项目将支持蒙大拿州立大学的一名硕士研究生和几名本科生。研究结果将发表在同行评议的文章中，并在国家和国际会议上发表。PI有机会通过州和市政水处理办公室的联系在蒙大拿州当地传播结果。 布鲁斯K.汉密尔顿7/2/10

Abstract Proposal Title: Plant, Season, and Microbial Controls on Complete Denitrification in Treatment WetlandsPrincipal Investigator: Otto R. SteinInstitution: Montana State UniversityProposal No.: 1034434The objectives of this project are to determine the effects of wetland plant species and season on the removal of nitrate from constructed wetland microcosms at different organic carbon loading rates, and the relationship between rhizosphere microbial community dynamics and the composition of gaseous emissions from denitrification. The overall goals of the research are to minimize the NO3 and N20 in treated wastewater effluent and gaseous emissions and to maximize the amount of N2 produced during denitrification in treatment wetlands. It is anticipated that the research will yield useful data on the optimal combination of plant species and operating conditions for use in constructed wetlands for tertiary treatment of municipal waste water. The project will support one masters-level graduate student and several undergraduate students at Montana State University. The results will be published in peer-reviewed articles and presented at national and international conferences. The PI has the opportunity to disseminate the results locally in Montana thru contacts in the state and municipal water treatment offices. Bruce K. Hamilton7/2/10
