摘要
本文以30.00mg/L的氨氮模拟废水为对象,分别研究了氨氮废水的两种处理方法:吸附法和折点加氯法。附法选用人造沸石作为吸附材料,研究结果表明:当人造沸石投加量为4g/30m L、p H值为7、吸附时间为90min去除氨氮的效果最佳;折点加氯法选用次氯酸钠作为脱除氨氮的试剂,研究结果表明:当氯与氨氮的摩尔量比为2.0、p H值为8脱除氨氮的效果最佳。
In this paper, based on the 30.00mg/L ammonia nitrogen wastewater as the object, the two methods for the treatment of ammonia nitrogen wastewater were studied.Artifcial zeolite was selected as adsorbent material, the results showed that： when the dosage of artifcial zeolite was4g/30mL, pH was 7, and the adsorption time was 90min, the removal of ammonia nitrogen was the best; Sodium hypochlorite was used as reagents for the removal of ammonia nitrogen, the results showed that： when the molar ratio of chlorine to ammonia nitrogen was 2.0, and the pH value was 8, the effect of ammonia nitrogen removal was the best.
