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。
There are many kinds of NH_3-N wastewater treatment techniques. Physical-chemical treatment techniques mainly include: air stripping process, break-point chlorination process, chemical precipitation process, ion exchange process, liquid membrane process, electrodialysis 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.
