Guangxi is the manganese sand out of the origin of the three because of its high content of manganese sand rich and famous - manganese dioxide manganese Guangxi area probably between 30% -45%, the highest content can sometimes reach 50%. Because manganese dioxide sand filter higher manganese content, the quality is better, therefore, Guangxi has been considered the origin of high-quality manganese sand have been widely praised. It is not to say that as long as the production of manganese sand filter Guangxi certainly good quality? The answer is no. Guangxi really can produce high levels of manganese sand filter, which is less than the other major mining area, but it does not mean that as long as the production of Guangxi manganese sand filter quality is certainly good. Guangxi is a province southwest of manganese sand, its large size, the production of manganese mining sand lot, but can produce high levels of manganese placer where mining is limited to Mashan County, Guangxi, rather than all of mine are able to produce high levels of manganese, so consumers do not just hear the manganese sand Guangxi region feel good quality, to ask that the mine in Guangxi produced. In fact, for manganese manganese sand filter standards are generally content to other areas, such as Liaoning and Hebei and the like produced manganese sand filter is also good. Therefore Guangxi was able to produce high levels of manganese sand filter, but does not mean that as long as the production of Guangxi manganese sand filter quality is necessarily good, Mashan County, Guangxi only can produce high levels of manganese sand filter, Guangxi Other region produces manganese sand filter is not good Mashan mine produced ore quality, so consumers buy manganese sand filter, I heard Guangxi produced so the quality is good, be sure to ask with the increasingly serious groundwater pollution, groundwater pollution at the source - the "iron waste water" more stringent treatment. The steel wastewater treatment because many pollutants in sewage, and our current processing technology is not perfect manganese sand filter works, used in the iron and steel waste water treatment or chemical treatment, chemicals likely to cause secondary pollution, which is a major problem plagued China's steel wastewater treatment. Since manganese sand filter to remove excessive iron in groundwater, so it can not be the source of the iron and steel wastewater it? Natural manganese sand iron content of iron in addition to groundwater is a contact catalytic iron removal process, suitable for less than 20mg / L of iron. High manganese natural manganese sand containing a can of water oxidation of ferrous iron to ferric iron, while the catalytic surface "active membrane" form manganese sand filter specifications to further enhance the effect of removing iron. After iron water aeration, only once by the natural manganese sand filter, you can complete the entire process in addition to iron. But the content of iron in the steel plant wastewater, far more than the content of iron in groundwater, the current manganese sand iron capacity has not yet reached the purpose of removal, that is, the steel mill wastewater using manganese sand filter is there will not be completely clear effect. Technological breakthrough can only look forward and hope for an early settlement of the steel wastewater pollution of groundwater.
