青泉直销优质锰砂滤料 天然环保锰砂

      锰砂滤料外观粗糙，呈黑褐色，近圆形，具有良好的除锰除铁功能，是给水排水行业最理想的产品。晶粒细密、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、单调、磁选、筛分、除尘等工艺成砂。再把加工好的锰砂按级配调合而成。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。首要成份是二氧化锰，含量在35%-45%之间。用它处理地下水操作方便，占地面积小，工程造价低，长效安稳，效力周期在5年以上，易于处理，不填加任何化学药剂即可抵达去除水中铁，锰砷等有害物质的目的，水质完全抵达国家饮用水标准，是非常好的地下水滤料。

      锰砂滤料的锰形态主要以二氧化锰为主，用户可根椐不同的处理目的。天然锰砂能将水中二价铁氧化成三价铁，同时在锰砂表面形成有催化作用的“活性滤膜”，为了保障活性滤膜能持续发挥作用，锰砂滤罐要适时进行反冲洗，保证锰砂表面不结垢。为了进一步增强除铁效果，在锰砂过滤罐之前加一道曝气处理工艺，使低价铁离子氧化成高价铁离子，是高价铁离子氧化成三价铁离子，形成沉淀，最终含铁水只经天然锰砂一次过滤，就能完成全部的除铁过程。

Manganese sand filter material appearance coarse, dark brown, suborbicular, has the good function of manganese iron removal, feed water and drainage industry is the ideal product. Grain fine, mechanical strength, strong chemical activity, invulnerability to breakage of natural manganese ores, insoluble in water. After the water washing grinding in removing impurity, drab, magnetic separation, screening, dust removal technology into sand, etc. Then processed manganese sand according to the grading blending. In unit volume specific surface area of the largest section carrying capacity of the strongest, the catalytic oxidation of the largest and the smallest backwash turnover. Principal component is manganese dioxide, content is between 35% and 45%. Deal with groundwater with its easy operation, cover an area of an area small, low engineering cost, long-term stability, validity period in more than 5 years, easy to handle, do not add any chemicals can be arrived in removing water iron, manganese, arsenic and other harmful substances, the purpose of water quality completely reach national drinking water standard, groundwater is a very good filter material.

Manganese manganese sand filter materials are mainly composed of manganese dioxide form, the user can root tree different treatment purposes. Natural manganese sand ferrous iron in water can be oxidized to ferric iron, manganese sand surface at the same time have a catalytic role of "active filter membrane", in order to ensure the active membrane filter can continue to play a role, manganese sand filter tank to reverse flushing timely, ensure the manganese sand surface fouling. In order to further enhance the effect of iron and manganese sand filtering tank before an additional layer of aeration process, make the low iron oxide into high iron ions, is, and the price is oxidized to ferric iron iron ions, formation of precipitation, finally hot metal containing only JingTianRan manganese sand filter, can finish all of the iron removal process.

锰砂滤料除铁原理

      对使用天然MnO2矿砂除铁，其原理有二种：一种是以所谓滤膜的作用，锰砂表面有一层较强的氧化作用。另一种是锰矿砂本身反铁催化作用，将水中的二价铁催化成三价铁，再把三价铁附着在锰矿砂颗粒表面从而起到除铁的目的。天然二氧化锰能氧化水中二价铁为三价铁使其沉淀除去，使水清净。二氧化锰被水中的溶解氧氧化成七价锰的氧化物。七价锰再将水中的二价铁氧化成三价铁。天然锰矿砂是一种很强的氧化剂，能对水中二价铁起氧化作用。

      在除铁锰滤池中运行时，水中低价铁锰离子先被覆合锰砂滤膜吸附，然后被氧化和水解，生成氢氧化物水合分子[Fe(OH)3XH2O]和[Mn(OH)nXH2O]形成的活性滤膜，并作为新的催化剂参与接触氧化反应，使活性滤膜有随着使用增厚的趋势，形成了覆合锰砂的自修复特性,使用一年的覆合锰砂，锰砂滤料中锰含量增加18.2%，铁含量增加4.8%；使用两年半的锰含量增加了27.3%，铁含量增加14.3%.锰砂容重较低(为1.55～1.60g/cm3)，锰砂滤料特别适用于大中型水厂的虹吸除铁锰滤池和各型除铁锰滤罐。

To use natural MnO2 in addition to iron ore, and its principle has two kinds: one is the so-called membrane filter, manganese sand surface with a layer of strong oxidation. The other is a manganese ores itself against iron catalyst, the ferrous iron catalyst in the water into ferric iron, then the ferric iron attached in manganese ores to the purpose of the iron particles surface. Natural manganese dioxide can ferrous iron in water as the ferric iron oxide precipitate removal, make the water clean. Manganese dioxide oxidation by the dissolved oxygen in the water into seven valence of manganese oxide. Ferrous iron water seven valence of manganese and then oxidized to ferric iron. Natural manganese ores is a strong oxidant, oxidation of ferrous iron in water.

In iron manganese filter is running, the water price iron manganese ion coating and manganese sand filter membrane adsorption, then by oxidation and hydrolysis, generate hydroxyl hydration molecule [Fe (OH) 3 xh2o] and [Mn (OH) nXH2O] formation of the active filter membrane, and participates in the contact oxidation reaction, as a new catalyst to make active membrane filter with the use of thickening trend, formed the draping self-healing properties of manganese sand, using a year combined with manganese sand, manganese content in manganese sand filter materials increased by 18.2%, iron content increased by 4.8%; Use two and a half years of manganese content increased by 27.3%, iron content increased by 14.3% for manganese ore with low bulk density (1.55 ~ 1.60 g/cm3), manganese sand filter material especially suitable for large and medium-sized waterworks siphon iron manganese filter and various iron and manganese removal filter tank.

      天然锰砂除铁是一种接触催化除铁工艺，适合于地下水含铁量小于20mg/L的除铁。含铁水经曝气后，只经天然锰砂一次过滤，就能完成全部除铁过程。

      锰砂滤料常用于生活饮用水的除铁、除锰过滤装置，滤水效果非常良好。主要用于降低水中的铁锰铁和锰总含量，根据我国生活饮用水卫生标准规其铁含量≤0.3㎎/L，锰含量≤0.1㎎/L，长时间饮用含铁含锰量过高的水会严重影响身体健康。

      对于纺织印染、食品等行业的产品会生成斑点；对生产设备腐蚀能力强；用于矿泉水、纯净水、离子水生产线的预处理除铁锰沉淀，以及地热工程和泳池工程的前期水处理除铁除锰等。
