摘要
以天然磷矿粉制备的羟基磷灰石(HAP)作为吸附剂,处理模拟含Fe3+废水。实验结果表明,在HAP加入量为1.0 g/L、初始模拟废水pH为3.00、反应温度为室温的最佳条件下,处理初始Fe3+质量浓度为150 mg/L的模拟废水,反应90 min后Fe3+去除率为99.89%,处理后模拟废水中Fe3+质量浓度为0.15 mg/L,低于0.30 mg/L,达到GB5749—2006《生活饮用水卫生标准》的要求。
The simulated Fe3＋-containing wastewater was treated using hydroxyapatite（HAP） prepared from ground phosphate rock as adsorbent.Under the optimum conditions of HAP dosage 1.0 g/L,initial wastewater pH 3.00,room temperature,initial Fe3＋ mass concentration 150 mg/L and treatment time 90 min,the Fe3＋ removal rate is 99.89%,and the Fe3＋ mass concentration of the treated wastewater is 0.15 mg/L,which can meet the national discharge standard of GB5749-2006（0.30 mg/L）.
