摘要：

The　start-up　of　CANON　process　was　studied　to　reveal　adaptability　and　how　to　condense　time　of　start-up　with　a　lab-scale　experiment.　During　start-up　stage,　temperature　was　controlled　at　35°C　plusmn;1deg;C　H　was　7.39-8.01　and　free　ammonium　was　2.89-12.37　mg·L-1　Partial　nitritation　was　first　built　up　in　60th　day　and　kept　steady,　nitrite　accumulation　rate　(NO2--N/NOx--N)　was　up　to　98%.　In　the　160　day,　the　reactor　started　to　show　effects　of　anaerobic　ammonium　oxidation,　and　in　the　210　day,　CANON　process　was　started-up　under　aerobic　conditions　successfully,　and　total　nitrogen　removal　load　was　1.22　kg/(m3middot;　and　70%　removal　rate　on　average　was　attained.　When　using　ammonium　wastewater　without　organic　carbon　sources　as　influent,　there　are　two　signs　to　indicate　the　CANON　start-up:　first,　nitrogen　gas　was　produced　in　carriers;　the　other　one　was　the　ratio　of　total　nitrogen　loss　and　increased　nitrate　keep　steady,　and　in　this　study　average　ratio　was　8.61　compared　to　theoretical　value　8.
