生产各种规格 锰砂 30%含量（图）
锰砂简介：
锰砂滤料是采用优质天然锰矿石加工而成，外观呈褐色，对于地下水除铁、除锰过滤有独特的效果。
锰砂滤料是采用国内优质锰砂矿、晶粒致密、机械强度大、化学活性强、不易破碎、不溶于水的天然锰矿砂。经水洗打磨除杂、破碎、干燥、磁选、筛分、除尘等工艺加工成砂。再把加工好的锰砂按一定的级配调合而成。它具有水处理滤料最理想的级配比例，使它在单位体积内有最大的比表面积、最强的截污能力、最大的氧化催化作用和最小的反冲洗流失率。
锰砂滤料外观黑褐色，近圆形，主要成份是二氧化锰，含量在35%-45%之间。
采用锰砂滤料处理地下水，工艺简单，操作方便，工程造价低，长效稳定，服务周期在5年以上，易于管理，不填加任何化学药剂即可达到去除水中铁、锰、砷等有害物质的目的，水质完全达到国家饮用水标准，是非常好的地下水处理滤料。
锰砂的理化指标：
分析项目 测试数据 分析项目 测试数据
密度 2．66g/cm3 破碎率 ≤1.0%
堆密度 1.85 g/cm3 磨损率 ≤1.0%
含泥量 ≤ 2.5% MnO2 30-40%
锰砂的应用：
天然锰砂是一种很强的氧化剂，能对水中二价铁起氧化作用，常用于饮用水除铁、除锰过滤装置，地下水除铁除锰净化水质使用。
使用锰砂的注意事项：
锰砂的使用的年限，对含铁浓度高的地下水一般为3~5年，对含铁浓度低的地下水，使用年限更长，有的已逾十年。在有的天然锰砂滤池中，滤层上部的锰砂会逐渐形成球状的“锈砂”，“锈砂”表面有一层“活性滤膜”，仍具有接触催化除铁能力，所以，形成“铁砂”，不是天然锰砂失效的标志。当”锈砂“长大致使滤料粒径过粗而影响除铁效果时，才有必要更换部分滤料。所以，在我们的施工过程中要注意是否有“锈砂”的存在，如果有的话一定要辨别清楚“锈砂”的大小，如果是小的规格，可以继续使用，可以减少我们的工业成本，如果是大的规格，就要换掉，以免影响过滤水质。
Manganese sand:
Manganese sand filter is made of high quality natural manganese ore processing, the appearance of a brown, for groundwater in addition to iron, and manganese filter has a unique effect.
Manganese sand filter is used domestic high-quality manganese placer, grain density, high mechanical strength, strong chemical activity, not easily broken, insoluble
In water natural manganese ore. After washing, drying, crushing grinding impurity, magnetic separation, screening, dust and other processing into sand. The processing of manganese sand according to certain gradation are mixed into. It has a water treatment filter ideal gradation proportion, make it in unit volume has the largest surface area, most of the sewage interception capacity, maximal oxidative catalysis and minimal backwash erosion rate. Manganese sand filter looks dark brown, nearly circular, main component is manganese dioxide content of between 35%-45%. The manganese sand filter for groundwater treatment, has the advantages of simple process, convenient operation, low cost, long term stability, service period in more than 5 years, easy to manage, do not add any chemical medicament to remove water iron, manganese, arsenic and other harmful substances, quality fully meet the national drinking water standards, is a very good groundwater filter material.
Manganese sand physicochemical index:
Analysis project test data analysis project test data
The density of 2.66g/cm3 broken rate≤1%
Bunch density 1.85 g/cm3 abrasion rate≤1%
Mud content≤2.5% MnO2 30-40%
Application of manganese sand:
Natural manganese sand is a strong oxidizing agent, water price to two from the oxidation of iron, commonly used in drinking water in addition to iron and manganese removal filtration device, removing iron and manganese from groundwater purification of water use.
Matters needing attention in using manganese sand:
Manganese sand \'s use of the term, of iron containing high concentrations of groundwater is generally 3~5 years, of iron containing low concentration groundwater, longer service life, some more than ten years. In some natural manganese sand filter, manganese sand filter layer is gradually forming globose " rust sand ", " rust sand " surface has a layer of " active membrane ", still have a catalytic iron removal ability, therefore, forms the " iron ", is not the natural manganese sand failure sign. When the " rust " grow up in sand filter media size too rough and effects of iron removal effect, it is necessary to replace part of filter material. So, in our construction process should pay attention to whether there is a " rust sand " exist, if some words must discern " rust sand ", if it is small size, can continue to use, we can reduce the industrial cost, if it is a large size, will be replaced, so as not to affect the filtering water quality.
