| 摘 要： | 烧杯搅拌试验结果表明,高铁酸盐预氧化能够显著提高硫酸铝混凝、沉淀去除地表水中锰的效果,剩余锰浓度随高铁酸盐投量的增加而下降. 经过短时间的高铁酸盐预氧化即能使处理后总锰浓度大幅下降. pH是影响高铁酸盐除锰效能的重要因素,在天然地表水条件下,高铁酸盐都有良好的除锰效果.

| Abstract: | Jar tests of ferrate pre-oxidation upon manganese removal from surface water were conducted. Results showed that ferrate pre-oxidation enhanced the manganese removal by alum coagulation-sedimentation processes significantly, the concentration of residual manganese decreased with the increase of ferrate dosage. An obvious decrease of residual manganese was observed even at a short pre-oxidation time. pH was believed to be an important factor affecting manganese removal by ferrate pre-oxidation, and the pre-oxidation with ferrate was efficient for manganese removal under neutral condition of natural surface water. |
