Evaluation of full-scale biofilter with rockwool mixture treating ammonia gas from livestock manure composting.

摘要: NH3 removal by a full-scale biofilter with rockwool packing materials was studied measuring the gases and potential nitrification denitrification activities of those in order to improve biofiltration technology used livestock farms. The durable effective system for removing NH3, which varied turning manure composts. Furthermore, could be treated absence an extra increase two greenhouse gases, N2O CH4. Potential were estimated 8.2-12.2 mg N, 1.42-4.69 N/100 g dry samples per day, respectively. results suggested that would within where substrates, or NO3(-), have accumulated as result its operation. However, since percolate water contained high concentrations NH4(+) further improvement is required reducing nitrogenous compounds both water.
