What are the advantages of micro-electrolysis packing in treating high concentration industrial wastewater? What is better than the traditional iron-carbon filler? The density is 1 m3. how much is it?

Iron-carbon filler is a good product for pretreatment of high-concentration industrial wastewater and an essential material for micro-electrolysis process. It has a strong adsorption-flocculation effect, so that the residual suspended solids, toxic organic substances, heavy metal ion hydrates and organic macromolecules in wastewater are adsorbed-flocculated, precipitated and separated, and COD and heavy metals can be well removed to realize sewage purification.

Micro-electrolysis technology is an ideal process for treating organic wastewater with high concentration, high chroma, high salt content and difficult biodegradation, also known as internal electrolysis. Its technical principle is that the filler can generate electrolytic voltage in wastewater, pure iron is used as anode, iron carbide and impurities are used as cathode, and electrode reaction occurs, which opens and breaks the chain of cyclic and long-chain macromolecular organic compounds, cracks toxic functional groups of toxic and harmful organic pollutants, and effectively removes chromaticity and heavy metal ions in wastewater. The Fe ~ (2+) generated after tapping further releases electrons and oxidizes to Fe ~ (3+), and forms flocculant Fe (OH) _ 3 under the condition of adjusting pH to 8~9.

The traditional iron-carbon filler is easy to harden. Iron-carbon filler with large particle size and rough surface is in contact with wastewater for a long time, and it is easy to form an oxide film on the surface to wrap iron-carbon. If it takes a long time, it will lead to hardening and passivation, greatly reducing the efficiency of wastewater treatment, and it needs regular pickling and activation. In severe cases, the system will crash and need to be replaced, and the cost is very high.

The packing density of FCM iron-carbon microelectrolysis filler is1.1-1.4t/m? The size is 12- 18㎜, and the specification is black spherical, which can solve the hardening problem of iron-carbon filler well.
