摘要：

This　paper　studied　the　transformation　regularities　of　key　evaluation　indicators,　such　as　carbon,　nitrogen　and　humic　acid　during　ultra-high　temperature　aerobic　composting　process.　The　results　showed　that　SCOD　increased　from　23.18mg/g　to　47.　49mg/g　and　then　decreased　to　30.67mg/g.　TOC　and　TN　respectively　decreased　from　207.45mg/g　and　45.40mg/g　to　157.86mg/g　and　38.23mg/g　in　the　previous　seven　days　and　almost　remains　constant　after　35days.　In　addition,　the　content　of　NH　4　+　-N　incrased　from　9.89mg/g　to　14.04mg/g,　but　the　sum　of　NO　2　-　-N　and　NO　3　-　-N　(about　0.07mg/g)　was　less　than　2%　of　TN.　The　loss　of　TN　was　as　high　as　82.87%,　and　it　mainly　attributed　to　ammonia　volatilization.　Humic　acid　increased　from　115.12mg/g　to　214.　11mg/g　in　previous　seven　days　and　alomost　remains　154.47mg/g　after　21days.　Although　E4/E6value　ranged　between　3.49　and　4.23,　it　showed　an　increasing　trend　in　total.　Hence,　it　is　not　suitable　for　maturity　evaluation.　©　2018,　Editorial　Board　of　China　Environmental　Science.　All　right　reserved.
