摘　　要：为了探索高氨氮水产养殖废水处理新技术,采用短程电极生物膜工艺同时在硝化区、反硝化区各设1组电源控制反应。研究结果显示:亚硝化细菌利用好氧区阳极碳棒电解产生的氧使氨氮转化为亚硝酸盐氮;反硝化菌利用反硝化区阴极碳棒电解产生的氢实现脱氮。实验的主要影响因素是p H和温度,反硝化区的电流对实验有一定的促进作用,次要的影响因素为C/N、水力停留时间和氨氮浓度。In order to develop new technology for the treatment of aquaculture wastewater with high content of ammonia nitrogen,the short-range electrode bio-membrane process has been used and power control reaction are established,one group each for both of the nitrification zone and the denitrification zone at the same time. The experimental results show that nitrite bacteria transforms ammonia nitrogen into nitrite nitrogen by using the oxygen produced from the electrolysis of anodic kryptol in denitrification zone,while denitrifying bacteria uses the hydrogen produced from the electrolysis of cathodic kryptol in the denitrification zone,to accomplish denitrification. The main influencing factors of this test are H and temperature. The current intensity in the denitrification zone has a promotive effect on the experimental results. The secondary influencing factors are C/N,HRT and the ammonia nitrogen concentration.
