A bench-scale study on swine manure stabilization for odour control was conducted using
\nbatch aeration reactors. In trial 1, two aeration lengths, i.e., 0.5 and 4.0 day, were used
\nunder uncontrolled ambient temperature that increased gradually over the experimental
\nperiod. While in trial 2, a 16.0-day aeration scheme was employed under constant 17 1C. An
\nairflow rate of 1.2 L\/s\/m3 was used for both trials to aerate batch reactors containing
\nfinishing pig manure with initial total solids (TS) levels ranging from 0.5 to 4.0%. Manure
\nstabilization during the 90-day post-treatment storage was evaluated by the changes in
\norganic materials, nitrogen and volatile fatty acids (VFA). The odour generation potential in
\nthe treated manure was determined by the changes in VFA. Up to 827mL of liquid was lost
\ndue to aeration related foaming. The reductions in total volatile solids (TVS), 5-day
\nbiochemical oxygen demand (BOD5), total Kjeldahl nitrogen (TKN) and VFA during storage
\nwere improved when aeration length increased. Low solids levels offered a more
\nadvantageous circumstance for manure stabilization and odour control. Biodegradation
\nof organic matter, removal of nitrogen, and breakdown of VFA would increase with
\nincreasing ambient temperature. VFA removals in manure under 16.0-day aeration were
\nhigher than those under 0.5- and 4.0-day aeration; however, VFA regeneration started to
\nexceed its consumption on day 20 (4 days after the aeration treatment). BOD5 was the best
\nestimate of VFA concentration in the aerated manure during storage. The 4.0-day aeration
\nscheme was sufficient to stabilize manure to effectively assuage odour generation potential
\nduring the 90-day storage under increasing ambient temperature conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"
