摘　　要：采用石灰乳中和并沉淀味精废水中的硫酸盐。试验结果表明:CaO的最佳添加量约为20g/L废水,SO42-的浓度可以从8000mg/L降到450mg/L,去除率可达90%。Calcium oxide was used to neutralize the acidic glutamate wastewater and precipitate the high concentration of SO4^2-.The result shows that the optimized amount of calcium oxide added was about 20 grams per liter wastewater and the concentration of SO4^2- could be reduced from 8000 milligrams per liter to about 450 milligrams per liter, with removing rate higher than 90%.
