Weifang Puyinworun Environmental Protection Technology Co., Ltd. is a professional manufacturer of micro-electrolytic fillers/iron-carbon fillers with the largest scale and sales volume in China. The company's fillers are jointly developed with Sun Yat-sen University and formed a structural alloy structure after high-temperature sintering at 1050 degrees. Effectively remove high concentration of organic matter in wastewater, reduce cod of wastewater, improve biodegradability of wastewater, remove color, break ring and break chain; product material has iron, carbon, activator and metal catalytic element, which solves the problem of traditional packing and passivation of filler , to form their own unique product advantages: no knots, no passivation, no replacement, high strength, 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.
Iron carbon filler features:
1. Solve the problem of packing, passivation, activation and replacement of micro-electrolytic wastewater treatment process, and has the advantages of continuous high-activity iron bed. Compared with the traditional iron-carbon filler loss, the loss is more than 60%, and the amount of sludge generated by the treatment is reduced by more than 50%.
2. The internal electrolysis anode and cathode and the catalyst form a structural alloy structure through high temperature, which does not easily separate the anode and the cathode as the iron-carbon mixed composition, and affects the primary battery reaction. The regular micro-electrolytic filler has long service life, convenient operation and maintenance, and only consumes a small amount of micro-electrolytic filler during the treatment. Micro-electrolysis is only required to be added periodically, depending on the volume of consumption, without replacement.
3, using microporous activation technology, large specific surface area, coupled with the addition of catalyst, provides greater current density and better micro-electrolysis reaction for wastewater treatment, and the reaction rate is fast.
4. Due to the dual functions of micro-electrolysis and catalyst, the conventional iron-carbon filler is used for the treatment of large organic matter concentration, high toxicity, high chroma and difficult biochemical wastewater. The COD removal rate in wastewater is generally about 35%-60%. The removal rate of 95% or more and the increase of B/C ratio can greatly improve the biodegradability of wastewater;
5. The electrolytic treatment method can achieve the effect of chemical precipitation and phosphorus removal, and can also remove heavy metals by reduction. After micro-electrolysis treatment, the wastewater will form the original ferrous or iron ions in the water, which has better coagulation than ordinary coagulants. It does not need to add coagulant such as iron salt. The COD removal rate is high and will not be correct. Water causes secondary pollution.
6, Fe2+ catalytic effect, after the micro-electrolysis, H2O2, that is, Fenton oxidation process, the decomposing rate of CODcr of some refractory chemical wastewater can reach 75-95%. It has a good degradation effect on difficult-to-degrade organic substances containing fluoro, carbon double bonds, nitro groups and halogenated structures.
7. The technology encapsulates iron and metal catalysts with carbon by high-temperature sintering to form a structural iron-carbon structure. The integration of iron and carbon can avoid the generation of passivation. Although the exposed iron is passivated, the passivation layer can be reduced due to the friction between the particles, and the iron in the frame is not affected by the passivation.
