摘　　要：本文研究了石灰优化利用技术处理磷肥工业酸性废水,实验证明,该工艺不仅减少约20%的石灰用量,还副产经济价值较高的P2O5约34.4%的含磷渣。工艺流程短、操作简便,经济效益明显,为磷肥工业酸性废水的处理利用提供了一条有效途径。This paper investigates the improving treatment process with acidic wastewater from phosphate fertilizer industry by lime optimal utilization. The experiment shows that the technology not only reduced about 20%of the dosage of lime, but also received high economic value of phosphorus slag with about 34.4% P 2O5. The process was characterized by short process flow, simple operation and obvious economic benefits. The process is an effective approach to the treatment of acidic wastewater from phosphate fertilizer industry.
