厌氧氨氧化反应器的稳定性及其模糊评价

采用统计学和模糊数学方法对厌氧氨氧化（ANAMMOX）反应器的运行稳定性进行了定量的对比研究．结果表明：同一构型的反应器对不同类型的冲击负荷具有不同的效应，基质浓度冲击下反应器的稳定性参数值是水力负荷冲击下的1．68～5．44（平均为2．9）倍；ANAMMOX反应器的抗水力负荷冲击能力明显强于抗基质浓度冲击能力；不同构型的反应器对同一类型的负荷冲击也有不同的响应；颗粒污泥床的抗基质浓度；中击能力最强，生物膜反应器次之，厌氧序批式反应器（SBR）最弱；SBR的抗水力负荷冲击能力最强．颗粒污泥床次之，生物膜反应器最弱．模糊综合评价表明，颗粒污泥床的抗冲击负荷能力最强，生物膜反应器次之，SBR最弱．

Stability and Its Fuzzy Assessment of ANAMMOX Reactor

The performance stabilities of different ANAMMOX(Anaerobic Ammonium Oxidation) reactors were quantitatively compared and investigated by means of statistic and fuzzy mathematical methods.The results show that,for the reactors with the same configuration,the tolerance to the shock load is greatly affected by the load type,that the stability parameters of the reactor under the substrate shock load are 1.68 to 5.44(2.9 in average) times those of the reactor under the hydraulic shock load,that the ANAMMOX reactors are more tolerant to the(hydraulic) shock load than to the substrate shock load,that the reactors with different configurations display different performance stabilities under the same load,and that the granular sludge bed stands the first in the stability under the substrate shock load,followed by the biofilm reactor and the SBR(Sequencing Batch Reactor).However,SBR takes the first place under the hydraulic shock load,followed by the granular sludge bed and the biofilm reactor.Moreover,the results of fuzzy assessment indicate that the granular sludge bed is most stable to the shock load,while SBR is the most unstable of the three reactors.
