Wastewater treatment technology: catalytic iron-carbon microelectrolysis packing

Removing COD: By utilizing the oxidation process of iron carbon microelectrolysis, the macromolecular chains are broken. In addition to removing most of the COD value, it can also improve the B/C value, which is beneficial for subsequent biochemical treatment and shortens the biochemical time, making it extremely easy to meet the standard. Color removal: Through the oxidation process of iron carbon microelectrolysis, new oxygen is generated, which damages the color clusters and achieves the purpose of color removal, with a maximum removal rate of 98%. Removing heavy metals: By changing the chemical valence of heavy metal elements, they are converted into metal compound precipitates through catalysis and oxidation. The heavy metals in the concentrated sludge are then extracted separately to achieve removal efficiency, with a removal rate of up to 99%

Production process: 1350 ℃ high-temperature process - forming alloy structure, different from physical pressing and low-temperature products. Iron carbon content ratio: 75/15, ensuring the lowest consumption of fillers while maximizing the formation of more primary batteries. The introduction of catalysts: provides activity and stronger potential difference during electrochemical reactions to better degrade organic porous structures; provides larger specific surface area to improve reaction efficiency and reduce unit water investment. Pressure resistance strength: Maintain strength during use to ensure even air-water channels and prevent powdering and separation of anode and cathode. Inlet pH: Generally, the inlet pH is controlled at around 3, and the available operating conditions are between pH 2 and 4. Inlet aeration rate: The general air-water ratio is 3:1. Considering special circumstances, it is necessary to add atmospheric water for simultaneous adjustment. When designing, the air-water ratio is 10:1. Inlet temperature: generally above 5 ℃, the calcium hardness and alkalinity of micro electrolysis inlet water are less than 1500mg/L. The suspended solids in the influent of microelectrolysis should be less than 80mg/L. When the suspended solids in the influent exceed the limit, appropriate pre-treatment should be carried out; Oil and grease wastewater must be separated from oil and microelectrolyte fillers. Before use, attention should be paid to waterproofing and corrosion prevention. Once water is supplied during operation, there should always be water for protection. It should not be exposed to air for a long time to avoid oxidation in the air and affect use. During the operation of the microelectrolysis system, attention should be paid to the appropriate amount of aeration and prolonged repeated aeration should be avoided. The microelectrolysis system cannot operate under alkaline conditions for a long time. To ensure the smooth operation of the process, appropriate electrification control should be implemented for the main inlet conditions to avoid insufficient human control. Micro electrolysis packing should be a direct addition type packing, which does not need to be completely removed and replaced. It can be directly put into the equipment
