The aerated wetland reactor outperformed the non-aerated one in the removal of organic matters, NH4-N and aromatic amines. The T-P removal efficiency for both wetland reactors was not much different throughout the study and the supplementary aeration showed no significant effect on T-P removal. As influent AO7 concentration increased from 50 to 100mg/L, the performance in biodegradation of organic matters and nitrification in the non-aerated wetland reactor, and denitrification and decolorization in the aerated wetland reactor were affected. As HRT increased from 3 to 6d, the removal of NH4-N and NO3-N in the aerated wetland reactor was not significantly different, but the NH4-N removal efficiency improved tremendously in the non-aerated wetland reactor. 2010-11-16T01:19:07Z 2010-11-16T01:19:07Z 2010-12 Article Bioresource Technology, vol. 101(23), December 2010, pages 9049-9057 0960-8524 http://www.sciencedirect.com/science?_ob=MImg&_imagekey=B6V24-50HYG3W-4-F&_cdi=5692&_user=1659113&_pii=S0960852410012241&_origin=search&_coverDate=12%2F31%2F2010&_sk=998989976&view=c&wchp=dGLzVlb-zSkzS&md5=88432364e8f081ecadf4e1d954c39248&ie=/sdarticle.pdf http://hdl.handle.net/123456789/10223 en Elsevier Ltd.
