超声辅助改性粉煤灰对废水中氨氮去除率的影响
Influence of Ultrasound-assisted Modified Fly Ash on Removal of Ammonia Nitrogen in Wastewater
摘要
Abstract
The treatment of wastewater containing ammonia nitrogen using fly ash modified by ultrasound‐assisted was studied .The effects of modification type ,ultrasound power ,ultrasound time , modified temperature ,NaOH amount and concentration on removal of ammonia nitrogen were examined .The results show that the NaOH amount and concentration are no effect on the removal of ammonia nitrogen if keeps n(OH -) constant and modify 3 h under ultrasound power 240 W .When the modified temperature is 60 ℃ ,removal rate of ammonia nitrogen can reach 81 .9% and increases 34%than that of original fly ash .关键词
