摘要
研究了用化学法去除废水中的氨 :用 Mg(OH) 2 +H3 PO4作沉淀剂 ,在 p H为 9~ 11范围内使废水中的氨形成复合肥 Mg NH4PO4,一定配比下 ,氨的去除率可达 95 % .探讨了该反应的反应机理及不同 Mg(OH) 2 :H3 PO4配比、不同 p
Ammonia in wastewater can be removed by using chemical precipitants Mg(OH) 2 and H 3PO 4 to form a composite fertilizer MgNH 4PO 4, with the removal ratio of ammonia above 95% under the optimal conditions. The effects of pH value, precipitant constitutions and the initial concentration of ammonia in the wastewater on ammonia removal efficiency are disscussed.
