【正文】 12]。 OLAND工藝技術(shù)要點 溶解氧控制 在限氧亞硝化過程中，低溶解氧條件下氨氧化菌的增殖速率加快，補償了由于低氧所造成的代謝活動下降，使得整個硝化階段中氨氧化不受明顯影響。而Jetten[3]~，最佳pH值在8左右。在微氧條件下，亞硝酸菌將氨氮部分氧化成亞硝酸，消耗氧化創(chuàng)造ANAMMOX 過程所需的厭氧環(huán)境；產(chǎn)生的亞硝酸與部分剩余的氨氮發(fā)生 ANAMMOX 反應(yīng)生成氮氣。一方面AOB和AAOB都要求適宜的酸堿度，另一方面，pH 會對真正的反應(yīng)基質(zhì) NH3和HNO2在液相中的分配比例產(chǎn)生影響。低DO濃度也有利于抑制NOB，從而有利于維持短程硝化，將氨氮氧化控制在亞硝酸鹽階段。參考文獻[1] 馮玉成,王建龍,[J].微生物學(xué)通報,2001,28（4）:88~91[2] Hellinga C,Schellen AAJC,Mulder JW,van Loosdrecht MCM and Heijen Sharonprocess:an innovative method for nitrogen removal from ammonium rich waste Science and Technology,1998,37(9):135~142[3] Mike SM Jetten ,et principles in the microbial conversion of nitrogen Leeuwenhoek,1997,71:75~93[4] 鄭平,徐向陽,[M]，北京：科學(xué)出版社，2004[5] 左劍惡,—SHARONANAMMOX組合工藝[J],給水排水,2001,27(10):22~24[6] Keisuke Hanaki,et at low levels of dissolved oxygen with and without organic in a suspended—growth Res,1990,24(3)；297~302[7] Van Kempen R,Mulder JW,Uijterlinde CA and van loosdrecht :full scale experience of the SHARON process foe the treatment of rejection water of disgested sludge Science and Technology,2001,44(1):145~152[8] A Mulder,et ammonium oxidation discovered in a denitrifying fluidized bed Microbiology ,16:177~184[9] Van de Graff A A,et oxidation of ammonium is a biologically mediated Microbiol,1995,61(4):1246~1251[10]Mike S M Jetten,et anaerobic oxidation of ammonium, FEMS Microbiology Reviews,1999,22:421~437[11]Strous M,Heijnen JJ,Kuenen JG and Jetten sequencing batch reactor as powerful tool to study very slowly growing microorganisms,Applied and Environmental Microbiology,1998,50(5)；589~596[12]Marc Strous,et removal from concentrated waste streams with anaerobic ammonium oxidation(Anammox)process in different reator Res,
