摘　　要：水库原水作为水厂水源在夏季经常出现铁、锰离子超标情况。原水中的锰离子一般采用高锰酸钾氧化法进行去除。水厂通过安装锰在线分析仪掌握原水中二价锰离子变化情况,进而确定高锰酸钾投加量。文章分析了陶瓷膜预处理器在提高锰在线分析仪数据准确性方面的适用性及处理效果。结果表明,使用陶瓷膜预处理器进行预处理后,锰在线分析仪检测准确度和稳定性有了显著提高,检测结果误差率由15.4%降至3.3%,检测结果漂移率从7.8%降至1.7%。原水锰离子检测精度的提高,优化并降低了水厂高锰酸钾用量,提高了出厂水锰离子合格率。As the source of the water plant,the raw water of reservoir often has excessive iron and manganese ions in summer.Manganese ions in raw water are generally removed by potassium permanganate oxidation.The water plant mastered the change of divalent manganese ions in raw water by installing a manganese online analyzer,and then determined the dosage of the potassium permanganate.This paper analyzes the applicability and treatment effect of ceramic membrane preprocessor in improving the data accuracy of the manganese online analyzer.The results showed that the accuracy and stability of the manganese on-line analyzer were significantly improved after the pretreatment with the ceramic membrane preprocessor.The error rate of the test results was reduced from 15.4%to 3.3%,and the drift rate of the test results was reduced from 7.8%to 1.7%.The improvement of the detection accuracy of raw water manganese ions optimizes and reduces the amount of potassium permanganate in the water plant,and improves the qualified rate of manganese ions in the finished water.
