The reaction mechanics , operation conditions and influence factors of anaerobic ammonium oxidation ( anammox ) for biological nitrogen removal are summarized , and feasibility of anammox with sharon and potential of anammox are also reviewed 摘要综述厌氧氨氧化微生物脱氨的反应机理、运行条件及影响因素，介绍厌氧氮氧化辅以中温亚硝化生物脱氮的可行性，以及厌氧氨氧化的发展前景。
The population distribution of physiological groups of bacteria ， including ammonifying bacteria , denitrifying bacteria , nitrobacteria and nitroso bacteria , organic phosphate dissolving bacteria and inorganic phosphate dissolving bacteria in water body and sediment of suzhou creek are studied with mpn and flat account method from jan . 2002 to mar . 2003 . the role of these physiological groups of bacteria in suzhou creek aquatic ecosystem is discussed 用最大可能数( mpn )法和平板计数法，于2002年1月2003年3月对苏州河水体和底泥中的主要微生物功能菌群? ?包括有机磷分解菌、无机磷分解菌、氨化菌、亚硝化菌、硝化菌和反硝化菌等进行了生态调查，并分析探讨了它们在苏州河水生态系统中的作用。
In varous determination systems , the potassium bromate - organicdye system and the system based on nitrosation reaction arc the main systems for determination of nitrite by fluorophotometry in the present time , and using the surface active agent to enhance determination sensitivity is the research content and one of directions 在各种测定体系中，溴酸钾有机染料体系和基于亚硝化反应体系是目前荧光光度法测定亚硝酸根的主要体系，利用表面活性剂提高测定的灵敏度是研究内容和方向之一。
1 . ecological effects of long - term organophasphate pesticides contamination on soil microflora the long - term effects of organophosphate pesticides contamination on soil microflora were investigated in the present study . little difference in total counts of bacteria , actinomycetes and fungi was observed between the contaminated and the non - contaminated soil . compared with the control there were a slight decrease in total counts of free - living nitrogen - fixer and denitrifying bacteria and a significant increase in those of ammonifying and ammonia - oxidizing and nitrifying _ bacteria in the methylparathion contaminated soil 一、甲基对硫磷长期污染对土壤微生物的生态学效应研究了有机磷农药甲基对硫磷长期污染对土壤微生物的影响，实验表明：土壤细菌、放线菌、真菌总的数量影响不大；自生固氮菌和反硝化细菌数量减少；氨化细菌、亚硝化细菌、硝化细菌的数量在污染土壤中却有所增加；与对照土壤相比，污染土壤呼吸作用下降了29 . 93 ；氨化作用和硝化作用强度得到增强。
