【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20 g.L-1废水,SO42-的浓度可以从8000 mg.L-1降到450 mg.L-1,去除率可达90%。更多还原

【Abstract】 Calcium oxide was used to neutralize the acidic glutamate wastewater and precipitate the high concentration of SO₄^2-.The result showed that the optimum adding amount of calcium oxide was 20 g/L wastewater,the concentration of SO₄^2- could be reduced from 8000 mg/L to 450 mg/L,and the removing rate was up to 90%.更多还原
