AUR (ammonia-nitrogen utilization rate), NUR (nitrate-nitrogen utilization rate) and OUR (oxygen utilization rate) parameters obtained from the consumption curve slope of activated sludge test could evaluate effectively the bioactivity of SBR sludge.

• 由活性污泥实验消耗曲线斜率取得氨氮利用率(AUR)、硝态氮利用率(NUR)、氧气利用率(OUR)3个参数；可以有效评价SBR污泥生物活性.
