改性稻壳去除低浓度氨氮的研究
Study on Removing the Low Concentration of Ammonia and Nitrogen by Modifying Rice Husk
摘要
Abstract
[Object]The aim was to study the modified rice husk adsorbed the low concentration of ammonia and nitrogen in wastewater. [ Method]The conditions of modified rice husk and treatment for adsorbing ammonia and nitrogen were determined by the single-factor test. [Result]The results showed that take the 10.0 ％ H2O2 as the modifier, the optimum modified conditions were temperature 100 ℃ ,time 30min and the optimum adsorption conditions were time 120 min ,temperature 23 ℃, pH 8.6 ,the rice husk and water quality volume 3.0 g/30 ml. Meanwhile,the structure and chemical bond of the rice husk haye changed after modifying. [ Conclusion] The modified rice husk can be used as a low-concentration ammonia and nitrogen wastewater treatment agent which had the utility value.关键词
