Beschreibung
Zusammenfassung:The invention is applicable to the technical field of water body remediation, and provides a preparation method of a modified adsorption material for low-concentration ammonia nitrogen in water, the modified adsorption material comprises the following components: fly ash and sodium hydroxide particles, and the mass ratio of the fly ash to the sodium hydroxide particles is 5: 8. The modified adsorption material is used as an adsorbent for repairing low-concentration ammonia nitrogen in water in a farmland irrigation area. The method is easy to operate, low in cost and good in effect, and overcomes the defects that a conventional method is complex in operation, high in cost and poor in effect. 发明适用于水体修复技术领域,提供了一种水中低浓度氨氮改性吸附材料的制备方法,包括一种改性吸附材料,所述改性吸附材料以下组分:粉煤灰和氢氧化钠颗粒,所述粉煤灰与氢氧化钠颗粒的质量比为5:8。将所述改性吸附材料作为吸附剂进行农田灌溉区水中低浓度氨氮的修复料。其操作简单,成本低廉,效果良好,弥补了常规方法操作复杂、成本昂贵和效果不佳的缺陷。
