Additive for removing ammonia nitrogen in electrolytic manganese residues and removal method thereof
The invention relates to an additive for removing ammonia nitrogen in electrolytic manganese residues and a removal method thereof. The additive comprises the following components in parts by weight:25-40 parts of an alkaline compound, 14-35 parts of fly ash, 25-46 parts of red mud, 85-100 parts of a solvent and 0.9-1.3 parts of a water reducing agent, wherein the alkaline compound comprises 15-35 parts of alkaline solid waste and 6-15 parts of a calcium-containing alkaline compound. Soluble ammonium salt in the electrolytic manganese residues with complex components can be converted into ammonia monohydrate which is easy to decompose, the ammonia monohydrate is converted into collected ammonia gas under the action of heat energy and mechanical energy, and a mixture obtained through a deamination treatment process can be directly mixed with materials such as slag and cement to prepare building materials meeting the national standard. According to the method, the purpose of efficientlyconverting the ammonia nitrogen unit in the electrolytic manganese slag is achieved, the electrolytic manganese slag product is prevented from emitting peculiar smell to harm the health of residents,and the purposes of comprehensively and cyclically utilizing resources and relieving the environmental pressure are achieved.
本发明涉及一种脱除电解锰渣中氨氮的添加剂及其脱除方法，所述添加剂的各个组分的重量份数为：碱性化合物25‑40份，粉煤灰14‑35份，赤泥25‑46份，溶剂85‑100份和减水剂0.9‑1.3份；其中，碱性化合物包括碱性固体废弃物15‑35份，含钙的碱性化合物6‑15份。本发明可将成分复杂的电解锰渣中的可溶性铵盐转化为易分解的一水合氨，在热能和机械能的作用下转化成已收集的氨气，经过脱氨处理工艺后得到的混合物可以直接与矿渣、水泥等材料混合制备符合国家标准的建筑材料。本发明实现了高效转变电解锰渣中的氨氮单位目的，防止电解锰渣制品散发异味危害居民身体健康，达成了综合、循环利用资源，减轻环境压力的目的。
