摘要
以景观水体为实验对象,阐述了沸石去除氨氮的吸附特性,实验结果表明:使用沸石处理高氨氮景观水,氨氮去除率超过90%;等温吸附试验研究结果显示所选用的沸石去除氨氮符合经典等温吸附模型朗格缪尔(Langmuir)等温模型,吸附极限值为4.642 3 mg/g;在25℃时,沸石对氨氮的去除率为93.4%。
Research in the landscape water for experimental objects to investigate the zeolite removing ammonia nitrogen adsorption characteristic. The experimental results show that: the use of zeolite deal with high ammonia nitrogen landscape water,ammonia nitrogen removal rate of 90% above,zeolite of ammonia nitrogen adsorption meet Langmuir isothermal model,the selection of zeolite experiment of ammonia nitrogen adsorption limit to 4. 642 3 mg / g,25 ℃ to the zeolite of ammonia nitrogen removal,the removal rate of 93. 4% .
