Refractory wastewater removal principle Category: Water waste removal micro-current effect and magnetic effect principle dyeing wastewater can be cut off between the iron-carbon dyeing wastewater pollutants chromophore, which makes decolorization. Wastewater, waste printed circuit board, reducing the ecological effects of heavy metal complex containing a new wastewater by ferric ions generated at the anode can get rid of heavy metal complexes, while using electrophoretic effect and ferric hydroxide co-precipitation, significantly reducing the wastewater The heavy metal complexes and wastewater COD. Nitrobenzene wastewater, aniline wastewater, wastewater, petrochemical wastewater, hydrogen peroxide wastewater, waste rubber chemicals, chemical wastewater containing benzene ring between the iron-carbon potential difference of 1.2V can produce tiny magnetic fields, electrons between the wastewater contaminants orientation under the influence of the magnetic force of the Games cutting carbon chains and carbon ring compounds, which play a role in breaking the ring scission, dramatically reducing cod while improving the biodegradability of the biodegradable waste into easy-degradable waste. Micro-current effects between pharmaceutical waste iron-carbon compounds can be stabilized medical expenses into water easily decomposed substance, while reducing cod, and hospital pathogens in wastewater is also a disinfectant. Heavy water color paper papermaking wastewater, pollutants and more micro electrolysis current effects, magnetic effects and Redox waste water can be more long chain of fiber carbohydrate into a monosaccharide or disaccharide material, greatly enhancing their biodegradability, into easily degradable substances. It can be completely removed with Fenton. Animal husbandry and wastewater, high concentration organic wastewater Microelectrolysis effects of high concentration organic wastewater can scission and destruction of the chromophore, reduce cod, ammonia, phosphide effect.

What is Microelectrolysis: Microelectrolysis is weak current use of iron and carbon spontaneous decomposition of a sewage treatment processes in wastewater pollutants. When in close contact with iron and carbon soaked in water solution, will automatically between the iron atoms and carbon atoms in the molecule to produce a weak internal current, the micro-current decomposition reaction in wastewater pollutants called micro electrolysis. 2, Micro-electrolysis principle: When the filler is immersed in an electrolyte solution, since there are difference between the electrode potential of 1.2V Fe and C, and thus the formation of numerous micro-cell system and its role in space constitute an electric field, an anode reaction generates a large number The Fe2 + enter waste water, and then oxidized to Fe3 +, forming a flocculant having a higher adsorption and flocculation activity. Cathodic reaction produces a large number of nascent [H] and [O], under acidic conditions, these active ingredients can redox reaction with the water in many of the components of the organic macromolecules chain scission degradation, thereby eliminating organic matter, especially color printing and dyeing wastewater, improve the biodegradability degree. Working principle is based on electrochemical oxidation - reduction, physical adsorption and flocculation of joint action for wastewater treatment. 3. Advantages: wide application, good effect, low cost, easy operation and maintenance, does not consume power resources, fast response, stable treatment effect, not cause secondary pollution, improve the biodegradability of wastewater can be achieved chemistry The precipitate phosphorus, except by reducing heavy metal, can be used as pre-treatment biological treatment, sludge sedimentation and biological beneficial biofilm. 4, where the carbon went after treatment: the filler is not large in the form of carbon particles are present, but in a very small form, the reaction with the iron-carbon consumption is constantly falling, fine carbon particles will fall off adsorption of contaminants into the sedimentation tank through flocculation and sedimentation. 5. Why do not need to replace the packing: iron and carbon is consumed at the same time, the proportion of iron and carbon filler will never change, so just change the amount of filler consumption, rather than qualitative. So with the filler consumption only need to add a new packing it. 6, STRENGTH: After high temperature sintering above 1050 degrees make the new iron-carbon micro-electrolysis filler physical strength can reach 1000Kg / CM2, enough to withstand water pressure 20m. Therefore, safe and reliable filling in Microelectrolysis column. 7, why not harden: harden phenomenon is due to the traditional packing iron particles are not uniformly dispersed carbon particles sake, easy to rust compaction between iron particles. The new micro-electrolysis filler through a special high-temperature sintering process makes the filler iron and carbon in the form of an inclusive framework for the presence of iron-carbon, iron, and carbon chain skeleton cross each other, which makes cross-iron particles are uniformly dispersed carbon particles and therefore it does not harden. 8, the physical structure: perforated frame structure, size 1cm * 3cm, specific surface area of ??1.2m2 / g, the proportion of 1.1 t / m3. 9, the treatment effect: the general reaction only 30-60min, cod removal rate of 50% --75% ammonia removal efficiency of about 40%, stable operation. 10, cost: the cost per square water treatment is about 0.4 to 0.6 yuan. 11, packing Overview: The new catalytic active micro-electrolysis filler - has a low potential difference of metal catalysts and high-temperature alloy fusion technology to produce microporous activated is made with iron-carbon integration, integration of catalyst, porous alloy framed structure, specific surface area Big, strong activity, high current density, the role of efficiency. Acting on the waste water can be efficiently removed cod, reduce color, improve biodegradability, stable treatment effect can be avoided during the operation of filling passivation, compaction and so on. 12, suitable for the type of waste: organic content specifically for large, high toxicity, high color, biorefractory wastewater treatment can significantly reduce the chroma of wastewater and cod, improve biodegradability, can be widely applied to printing and dyeing, chemical, electroplating, pharmaceutical, pesticide, alcohol and other types of industrial wastewater and treated water reuse project. 13, the technical characteristics: (1) anode and cathode and the catalyst is formed by high-temperature smelting of iron-carbon integrated to ensure that "primary cell" effect sustained action. Not like the iron-carbon physically mixed group with as prone to separate the anode and cathode, the impact of the original cell reaction. (2) a filler alloy formed microporous framework structure by high temperature smelting, large surface area, strong activity, not passive, not compacted, the anode and cathode by matching the different wastewater, wastewater treatment provides a high current density and better the effect of micro-electrolysis reaction, the reaction rate, and general industrial waste only takes 30-60 minutes, long-term stable and effective.
