改性油页岩灰渣处理景观湖水中氨氮的研究
Study on ammonia nitrogen adsorption from landscape lake by modified oil shale ash
摘要
Abstract
For the prevention against eutrophication of Landscape lake, oil shale ash sorbent was prepared from oil shale ash modified by H2SO4 solution under different reaction time. It was used to adsorb Ammonia nitrogen which contents was 5.3mg/L in Landscape Lake. The results show that the modified oil shale ash sorbent prepared by Acid leaching 30min had better adsorption capability to Ammonia nitrogen, and the adsorption quantity was lmg·g1 with sorbent 5g·L-1, reacytion time 60min, temperature 20 ℃. The Ammonia nitrogen adsorption of modified oil shale ash sorbent obeys the Freundlich isothermal absorption equation. The absorption reaction was physical adsorption and followed the first-order kinetic equation. Ammonia nitrogen contents satisfied the landscape uses atter the treatment.关键词
