摘　　要：采用L9(34)的正交设计法,以可溶性正磷酸盐下降率及pH值上升率为评定指标,对赤泥及粉煤灰处理磷石膏堆场废水的优化方案进行筛选。实验结果表明,降低可溶性磷酸盐含量的最佳方案为赤泥1.60g,粉煤灰0.80g,水样100ml,时间4d。提高pH的最佳方案为赤泥1.60g,粉煤灰0.40g,水样100ml,时间3d。L9 （34） orthogonal design was applied to storage yard by red mud and fly ash. The decreasing value were regarded as the evaluation indices to find reducing the resoluble orthophosphate is 1.60g of red ever, 1.60g of red mud, 0. 40g of fly ash, 100ml of select optimization scheme of phosphorus wastewater from the rate of resoluble orthophosphate and the increasing rate of pH the best scheme. The results indicated that the best plan for mud, 0. 80g of fly ash, 100 ml water sample in 4 days. Howwater sample and 3 days was the optimum condition of improving pH value.
