摘要
应用改性沸石对河道水体进行深度处理,能够十分有效地将其中所含中低浓度氨氮降至到1mg/L以下,达到GB3838—2002《地表水环境质量标准》中III类水氨氮水平。论文研究了在处理水体中氨氮时,停留时间、上升流速等对吸附的影响,同时考察了次氯酸钠氧化法与电化学氧化法对沸石脱附液再生的效果。
The application of modified zeolite in advanced treatment of river water can effectively reduce the concentration of ammonia nitrogen to less than 1 mg/L, which can achieve the Level of ammonia nitrogen of class III water of GB 3838—2002 "Surface Water Environmental Quality Standard". The paper studies the effects of residence time and upwelling velocity on the adsorption of ammonia nitrogen in water, and investigates the regeneration of zeolite desorption solution by sodium hypochlorite oxidation and electrochemical oxidation.
