When the system is flooded, numerous micro-battery systems are formed in the device, forming an electric field in its working space. The new ecology [H] and Fe2 + produced during the treatment can undergo redox reactions with many components in the wastewater, such as chromophores or color-promoting groups that can destroy colored substances in colored wastewater, even The chain reaches the effect of degradation and decolorization; the formed Fe2 + is further oxidized to Fe3 +, and their hydrates have strong adsorption-flocculation activity, especially after adding alkali to adjust the pH value to form ferrous hydroxide and ferric hydroxide colloid. Flocculants, their adsorption capacity is much higher than that of iron hydroxide colloid obtained by hydrolysis of general agents, which can adsorb a large number of fine particles, metal particles and organic macromolecules dispersed in water. Its working principle is based on electrochemistry, oxidation-reduction, physical adsorption. And the co-action of flocculation and sedimentation treats the wastewater. The method has the advantages of wide application range, good treatment effect, low cost, convenient operation and maintenance, and no need to consume power resources. The process for the treatment of refractory high chroma wastewater can not only greatly reduce the cod and chroma, but also greatly improve the biodegradability of the wastewater.
Traditionally, the micro-electrolytic materials used in the micro-electrolysis process are generally iron filings and charcoal. It is activated by acid and alkali before use. It is easy to passivate the knot during use, and it is easy to form because iron and carbon are in physical contact. The isolation layer makes the micro-electrolysis unable to continue and loses its effect, which leads to frequent replacement of the micro-electrolytic material, which not only has a large workload and high cost, but also affects the treatment effect and efficiency of the wastewater. In addition, the surface area of ​​the traditional micro-electrolytic material is too small, which requires a long time for wastewater treatment and increases the investment cost of tons of water, which seriously affects the utilization and promotion of the micro-electrolysis process.
Application scope of iron carbon filler: dye wastewater, coking wastewater, petrochemical wastewater, leather wastewater, papermaking wastewater, wood processing wastewater, electroplating wastewater, printing wastewater, mining wastewater, heavy metal-containing wastewater, pesticide wastewater.
Of course, the types of these wastewaters are still incomplete, but we can confidently say that as long as the type of wastewater is suitable for treatment with micro-electrolytic fillers or iron-carbon fillers, our products will definitely surprise you!
Weifang Puyinworun Environmental Protection Technology Co., Ltd. sincerely welcomes new and old customers to visit us. We sincerely hope to cooperate with people from all walks of life to create a beautiful home with clear water and blue sky, and let the beautiful homes pass on from generation to generation.
Weifang Puyinworun Environmental Protection Technology Co., Ltd. is a professional manufacturer of iron-carbon fillers for micro-electrolytic fillers with the largest scale and sales volume in China. The company's fillers are jointly developed with Sun Yat-sen University. After 1050 degrees high temperature sintering, it forms a structural alloy structure, which is effective. The high concentration of organic matter in the wastewater is removed, the cod of the wastewater is reduced, the biodegradability of the sewage is improved, the color is removed, and the broken chain is broken; the product material is iron, carbon, activator and metal catalytic element, which solves the problem of traditional packing and passivation of the filler. Forming its own unique product advantages: no binding, no passivation, no replacement, high strength and low loss (annual loss less than 15%).
In the spirit of excellence, the company has led a group of professional teams to maintain long-term close technical cooperation with Sun Yat-sen University. With strong technical strength and rapid development momentum, the quality, sales volume and output of iron-carbon fillers occupy the leading position in the country and win. The praise and trust of the majority of users, and many of the projects we have done have been promoted as a model project. Scope of application: electroplating wastewater, printing and dyeing wastewater, auxiliary wastewater, chemical wastewater, coking wastewater, circuit board wastewater, ammonia nitrogen wastewater, pharmaceutical wastewater, metal product wastewater, etc.
