| 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 have 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. |
