title: [Start-up by inoculation and operation of a CANON reactor with haydite as the carrier].
abstract: A CANON reactor with haydite as the carrier was started by incubating sludge from another CANON reactor and using synthetic inorganic ammonia rich wastewater as the raw water. Both start-up and operation were studied. The result showed that haydite can be a suitable carrier for CANON reactor. With this carrier, start-up of CANON reactor can be completed in 60 days with total nitrogen removal load up to 0.79 kg x (m3 x d)(-1), when the reactor was equipped with a water jacket to maintain the water temperature at 30 degrees C +/- 1 degrees C, and pH at 7.00-8.08, hydraulic retention time of 9 hours. The critical range of dissolve oxygen for CANON reactor was 1.12-1.69 mg x L(-1), and both characteristics of short-cut nitrification and ANAMMOX were stable. However, the CANON reactor can be instable if dissolve oxygen concentration increased above this range. Although the ratio of nitrate variation to total nitrogen variation (deltaNO3(-) -N/deltaTN) was 0.150-0.204, which deviated a little from its theoretical value, 0.127. The performance of CANON reactor kept relatively stable. The total nitrogen removal efficiency was up to 75.56% while total nitrogen removal load was 0.97 kg x (m3 x d)(-1), which means the temperature for CANON reactor can be decreased to 25 degrees C at least.
