With the development of industry, the difficulty of sewage treatment is also growing. Among the treatment technologies for refractory industrial wastewater, micro-electrolysis technology (iron-carbon filler water treatment process) is receiving increasing attention and has been widely used in engineering practice. At present, it is widely used in chemical, pesticide, dye, pharmaceutical and other high-color, biodegradable wastewater, used to reduce organic pollution and high biodegradability of wastewater. [Iron-carbon micro-electrolytic filler] Technical principle: The principle of iron internal electrolysis of wastewater is very simple, that is, the use of potential difference between iron-carbon particles has formed numerous fine primary batteries. These fine batteries are made of iron having a low potential as a cathode, and carbon having a high potential as an anode, and an electrochemical reaction occurs in an aqueous solution containing an acidic electrolyte. The result of the reaction is that the iron is corroded into divalent iron ions into the solution. Because of the coagulation effect of iron ions, it is absorbed by the particles with weak negative charge in the contaminants to form a relatively stable floc (also called iron mud) and removed.
Puyinworun environmentally friendly [iron-carbon micro-electrolytic filler] sewage treatment advantages:
(1) It can handle a variety of poisons at the same time, with small footprint, simple system structure, easy to finalize the whole device and industrialization of equipment manufacturing;
(2) Wide application range, applied in wastewater treatment in many industries, such as printing and dyeing wastewater, electroplating wastewater, petrochemical wastewater, etc., have achieved good results;
(3) The treatment effect is good. From the actual operation of each plant, the removal effect of the various poisons is ideal.
(4) Long service life, convenient operation and maintenance, as long as the micro-electrolysis tower (bed) is regularly added with filler.
Puyinworun environmentally friendly [iron-carbon micro-electrolytic filler] product process advantages:
(1) The anode and cathode and the catalyst form iron-carbon integration through high-temperature smelting, ensuring the "primary battery" effect to continue. It is not as easy to separate from the anode and cathode as the physical mix of iron and carbon, which affects the reaction of the primary battery.
(2) The filler is formed by high-temperature smelting to form a structure-type microporous alloy structure with large specific surface area, strong activity, no passivation, no slab, and the anode and cathode are matched for different wastewaters, providing greater current density and more for wastewater treatment. Good micro-electrolysis reaction effect, fast reaction rate, general medical wastewater only takes 30-60 minutes, long-term operation is stable and effective.
Puyinworun environmentally friendly [iron-carbon micro-electrolytic filler] product quality advantage: "Weifang Puyin Worun Environmental Protection Technology Co., Ltd." is located in the beautiful world kite capital----Weifang City, the precious metal produced by Puyinworun The iron-carbon micro-electrolytic filler is made of fine coking coal, and many customers have excellent feedback effects! Good craftsmanship, good products! Listening to the virtual, seeing is believing, welcome more customers to come to consult and inspect! Weifang Puyinworun Environmental Protection Technology Co., Ltd. is a professional manufacturer of iron and carbon fillers. The new iron-carbon filler produced is a fine product of water treatment materials. The newly developed iron-carbon filler is different from the iron-carbon filler in the past. Iron carbon filler, sintered at 1050 ° C high temperature (oxygen free)! ! ! The newly developed iron-carbon filler is not knotted, not passivated, free of replacement... and low loss! !
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, the loss is reduced by 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 role of iron-carbon microelectrolysis 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 chroma removal rate of 95% or more and the increase of the B/C ratio can greatly improve the biodegradability of the 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.
