摘要： 为了提高酸性矿山废水中和处理时的熟石灰利用率，减少药剂消耗，降低运营成本，针对马鞍山市某高锰酸性矿山废水处理过程中加药量大、污泥产生量大的问题，基于传统中和处理法，进行了分级中和处理的试验研究，确定了分级中和处理的目标 pH控制值。结果表明：采用熟石灰进行分级中和处理高锰酸性矿山废水，当一级中和控制废水的 pH 值为 5~6，二级中和控制废水的 pH 值为 9.8 时，分级中和处理的熟石灰总添加量为 2.23 g/L，相对于传统中和法石灰使用量可减少 40% 以上；分级中和处理产生的污泥量为 3.37 g/L，相对于传统中和法污泥的产生量可降低 65% 以上；二级中和处理时产生的污泥锰含量为 38.66%。采用分级中和处理可有效降低熟石灰使用量，减少污泥产生量。

Abstract: In order to improve the utilization rate of slaked lime in neutralization treatment of acid mine wastewater，reduce reagent consumption and reduce operating costs，aiming at the problems of large dosage and large sludge production in the treatment process of a high manganese acid mine wastewater in Maanshan City，based on the traditional neutralization treatment method，the experimental study of grading neutraliza⁃ tion treatment was carried out，and the target pH control value of grading neutralization treatment was deter⁃ mined. The results show that when the pH value of the first stage neutralization control wastewater is 5~6， and the pH value of the second stage neutralization control wastewater is 9.8，the total amount of hydrated lime added in the grading neutralization treatment is 2.23 g/L. The amount of hydrated lime was reduced by more than 40% compared with the traditional neutralization method. The amount of sludge produced by the grading neutralization treatment is 3.37 g/L，which can be reduced by more than 65% compared with the tra⁃ ditional neutralization method. The manganese content of the sludge produced during the secondary neutral⁃ ization treatment was 38.66%. The use of graded neutralization treatment can effectively reduce the amount of lime dosage and reduce the amount of sludge.
