  • 摘要: 赤泥与石灰粉（CaO和Ca（OH）2）按不同比例混合制成复合赤泥，通过投加实验考察了复合赤泥的除磷效果。结果证明，对于磷酸盐浓度为45 000 mg/L左右（以P计）的酸性工业废水，复合赤泥（赤泥与Ca（OH）2按质量比1：1混合）投加量为240 g/L，去除率为99.97%；对于10 mg/L左右的含磷废水，赤泥的最佳投加浓度为15 g/L，上清液磷浓度可降至0.30 mg/L，出水低于0.5 mg/L的排放标准。根据以上研究结果，提出了对高浓度酸性磷酸盐废水的处理宜采用复合赤泥再加原状赤泥的二级处理方法。
    Abstract: Composite red mud was got by the way that red mud and CaO or Ca(OH)2 were mixed in different proportions. Phosphate removal from industrial wastewater by composite red mud was studied. The results show that the removal rate is 99.97% when the initial phosphate concentration is approximately 45 000 mg/L and composite red mud (red mud and Ca (OH) 2, mass ratio 1:1) dosage is 240 g/L. For the initial phosphate concentration of approximately 10 mg/L, the phosphate concentration is reduced to 0.30 mg/L using raw red mud with the concentration of 15 g/L. The effluent concentration of phosphate (P) is less than 0.5 mg/L. Based on the results, a secondary treatment method including composite red mud and raw red mud could be used for high-phosphate acidic industrial wastewater.

摘要: 赤泥与石灰粉（CaO和Ca（OH）2）按不同比例混合制成复合赤泥，通过投加实验考察了复合赤泥的除磷效果。结果证明，对于磷酸盐浓度为45 000 mg/L左右（以P计）的酸性工业废水，复合赤泥（赤泥与Ca（OH）2按质量比1：1混合）投加量为240 g/L，去除率为99.97%；对于10 mg/L左右的含磷废水，赤泥的最佳投加浓度为15 g/L，上清液磷浓度可降至0.30 mg/L，出水低于0.5 mg/L的排放标准。根据以上研究结果，提出了对高浓度酸性磷酸盐废水的处理宜采用复合赤泥再加原状赤泥的二级处理方法。
