The article reviews the advanced research on screening sheepbreeds with high resistance against fasciolosis. Screening sheep breeds with high resistance against fasciolosis has been tested by measuring parameter of plasma such as packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin concen tration, glutamate dehydrogenase, gamma glutamyl transferase and aspartate trans ferase and percent take of metacercariae. High resistance of Indonesian thin tail sheep against Fasciola gigantica has been confirmed. The mechanism of high res istance and the time of killing Fasciola gigantica has also been described.

But the effluent ammonium in the anoxic reactor, where enough NO2 were present, was equal to the blank system, and no ammonium was converted to such nitrogen compounds as NO2- and N2 by Nitrosomonas eutropha using NO2 as electron acceptor, which maybe caused by lack of the function bacteria. There were two ANAMMOX reaction pathways in the one-stage autotrophic nitrogen removal system. One way was that after part of NH4+ was oxidized to NH2OH under aerobic conditions, NH2OH and NO2- were converted to N2O under anaerobic conditions, at last N2O was further converted to N2 which realized the nitrogen removal; Another way was that at first NO2- was reduced to NH2OH, NH2OH reacted with NH4+ to form N2H4, which was further converted to N2 subsequently, realizing the nitrogen removal.

结果表明：单级自养脱氮系统内6.72%的氨氮是通过吹脱等物化作用去除的，不超过6.02%的氨氮是通过传统硝化反硝化途径去除的，87.26%左右的氨氮是由自养脱氮途径去除的，自养脱氮反应起主要脱氮作用；在足够NO2存在且缺氧的条件下，单级自养脱氮系统内的出水氨氮浓度与空白反应器相当，NH4+并没有被亚硝化单胞菌以NO2为电子受体氧化为NO2-和N2等化合物而得以去除，可能是因为系统内不存在该代谢功能的亚硝化功能菌；单级自养脱氮系统内存在两条ANAMMOX反应途径：其中一条途径即NH4+在好氧条件下被氧化为NH2OH后，生成的NH2OH与系统内的NO2-在缺氧条件下被转化为N2O，N2O则进一步被转化为N2而实现氮的去除；另外一条途径即NO2-首先被还原为NH2OH，生成的NH2OH则与系统内的NH4+反应生成N2H4，N2H4继续被转化为N2而实现氮的去除。
