生产 25 30 35 40 45各种含量锰砂滤料锰砂催化剂

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。它具有水处理滤料的级配比例，使它在单位体积内有的比表面积、的截污能力、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*达到饮用水标准，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 profile:

Manganese sａnd filter material is made of high quality natural manganese ore and brown on the appearance, for groundwater iron and manganese removal filter has a unique effect.

Manganese sａnd filter materials are using high quality domestic manganese sand, grain density, mechanical strength, strong chemical activity, not easily broken, natural MengKuangSha does not dissolve in water. After the water washing grinding in removing impurity, crushing, drying, magnetic separation, screening, dust removal process into sand, etc. Then processed manganese sａnd according to certain gradation blending. It has the ideal water treatment filter, grading scale, making it in unit volume, specific surface area of the largest, the most powerful section carrying capacity, the catalytic oxidation of the largest and the smallest backwash turnover. Manganese sａnd filter material appearance of dark brown, suborbicular, ingredient is manganese dioxide, content is between 35% and 45%. Using manganese sａnd filter material processing of groundwater, the craft is simple, convenient operation, low engineering cost, long-term stability, the service period in 5 years, easy management, do not add any chemicals to remove the harmful material such as fe, mn, arsenic water, the purpose of the water quality fully meet the national drinking water standard, groundwater is a very good filter material processing.

Manganese ore of the physical and chemical indicators:

Analysis of test data analysis projects test data

Dense degree of 2.66 g/cm3 broken broken rate of 1.0% or less

Heap of dense degree of 1.85 g/cm3 ground loss rate of 1.0% or less

Clay content of 2.5% or less MnO2 30-2.5%

The application of manganese sand:

Natural manganese sａnd is a kind of strong oxidant, oxidation of ferrous iron in water, iron and manganese removal filter device used in drinking water, groundwater used to purify the water quality in addition to iron and manganese.

Use the matters needing attention of manganese sand:

Use fixed number of year, of manganese ore containing high concentration of iron is commonly 3 ~ 5 years of groundwater, the groundwater iron concentration is low, service life is longer, some of which have been more than ten years. In some natural manganese sａnd filter, filter layer of the upper manganese sａnd will gradually form spherical sａnd "rust", "sand" rust surface with a layer of "active filter membrane", still have contact with catalytic iron ability, therefore, form the "iron ore", is not a sign of natural manganese sａnd failure. Sａnd when "rust" grew up the particle size of the filter material is too thick and influence iron removal effect, it is necessary to replace part of the filter material. So, in our construction process should pay attention to whether there is the existence of the rust sａnd ", if any, must distinguish clearly the size of the sａnd "rust", if it is a small specifications, can continue to use, can reduce the cost of our industry, if it is a large specification, is about to change, so as not to affect filtered water quality.
