Abstract

This study was carried out to investigate the removal of 2,4,6-trinitrotoluene, nutrients such as nitrogen, phosphorous compounds in the wetland microcosms. Microcosm study indicated that TNT nutrients were more lastly reduced in the anaerobic condition. The major reductive transformation products included 2,4diamino-6-nitrotoluene (2,4-DANT) 2,6diamino-4-nitrotoluene (2,6-DANT) 4diamino-2,6-nitrotoluene (4-ADNT) 2diamino-4,6-nitrotoluene (2-ADNT). The experimental results for nitrogen removal showed that denitrification kom NO$\sub$3//$\^$-/ to NH$_3$ was dominant process at the bottom of marsh, but nitrification from NH$_3$ to NO$\sub$3//$\^$-/ was dominant on the top of marsh.
