Nitrogen-retaining property of compost in an aerobic thermophilic composting reactor for the sanitary

Fan BAI, Xiaochang WANG,

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 2,   Pages 228-234 doi: 10.1007/s11783-010-0022-7

Abstract: fertilizer, it would be beneficial if the composting conditions could be more precisely controlled for the retentionof fecal nitrogen as long as possible in the compost.Attention was paid to the characteristics of nitrogen transformation.The nitrogen loss was found to occur mainly in the first 24 h with the rapid depletion of inorganic nitrogenbut with an almost unchanged organic nitrogen content.

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 3, doi: 10.1007/s11783-019-1115-6

Abstract:

Longer HRT can enhance degradation rate of sulfamethoxazole in granular reactor.

Longer HRT can reduce accumulated concentrations of TCs and QNs in sludge.

Longer HRT may have increased relative abundances of ARGs in aerobic granules.
