Abstract
An up-flow botanical bioreactor was proposed as an economical and environmentally-friendly control process toremove the odorants, specifically ammonia and hydrogen sulfide, in exhaust gas. Liriope Platyphylla and HederaHelix were selected as the test plants, and were put into the lab-scale reactor filled with the ceramic media. During52 days of operation with ammonia loading of 1.16 g/m3·d, Liriope Platyphylla showed better performance inammonia removal. Liriope Platyphylla was further tested by the simultaneous loading of 6.96 g/m3·d for ammoniaand 1.00 g/m3·d for hydrogen sulfide. Microbial activity in the botanical reactor was greatly enhanced by mixedodorants rather than single odorants, and can contribute to removing odor in the exhaust gas. Biological uptakeby plants reached up to 20% of total nitrogen loading to the botanical reactor.
