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

提案标题：湿地处理中植物、季节和微生物控制对完全反硝化的影响主要调查者：奥托·R·斯泰因研究所：蒙大拿州立大学提案编号：1034434本项目的目标是确定不同有机碳负荷率下湿地植物种类和季节对人工湿地微生态中硝酸盐去除的影响，以及根际微生物群落动态和反硝化气体排放组成之间的关系。这项研究的总体目标是最大限度地减少处理后废水和气体排放中的N03和N20，并最大限度地增加处理湿地反硝化过程中产生的氮气量。预计这项研究将产生有用的数据，说明用于城市污水深度处理的人工湿地中植物种类和运行条件的最佳组合。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。研究结果将以同行评议文章的形式发表，并在国内和国际会议上公布。PI有机会通过州和市政水处理办公室的联系人在蒙大拿州当地传播结果。布鲁斯·K·汉密尔顿2010年7月2日
