中文摘要:
      氨氮去除方法有多种, 物理化学法有空气吹脱法、折点氯化法、化学沉淀法、液膜法、电渗析除氨氮法、催化湿式氧化法、土壤灌溉法、循环冷却水系统脱氨法;生物脱氮法可去除多种含氮化合物, 总氮去除率可达70%———95%, 主要有传统硝化反硝化、短程硝化反硝化、同时硝化反硝化、厌氧氨氧化。有时要采取多种技术的联合处理, 才能取长补短达到较好的处理效果。
英文摘要:
      There are many kinds of NH3-N wastewater treatment techniques. Physical-chemical treatment techniques mainly include :air stripping process ,break-point chlorina-tion process ,chemical precipitation process , ion exchange process , liquid membrane process , electrodialy sis process , catalytic - wet oxidation process , land irrigation process , cool recycle water system removing ammonia process ,etc. . Biological techniques can remove many kinds of nitrogen containing compounds , total nitrogen clearance is 70%———95%, mainly including traditional , short- distance , SND and ANAMMOX technique.Sometimes in order to overcome one technique's weakness by acquiring other's strong points and get good effect ,several techniques should be joined together.
