At present, due to the deterioration of the ecological environment, the structure of pollution factors is becoming more and more complicated, which makes handling more difficult. Goldfields across the country not only require stable compliance, but also require upgrading. In the face of the new environmental protection situation, wastewater, chemical, physical, ultrafiltration, micro Electrolytic electrodialysis, reverse osmosis, biochemical methods and other processes are applied alone or in stacks, which makes the wastewater treatment process more and more complicated, the operating cost is higher and higher, the area is larger, the investment cost is higher, and the environment Requirements and the need for environmental protection, our company has developed a "super-redox wastewater treatment device".
This device is suitable for the treatment of various heavy metals and organic waste water, involving industries such as electroplating, emulsions, mining, smelting, chemicals, medicine, pesticides, battery industries, agricultural product processing, waste infiltration fluids, mining, dyes, black odorous water, etc. Treated organic wastewater. The device covers two processes: high-frequency electric flocculation and high-frequency electric Fenton. The core is high-frequency electrochemistry. It has cutting disintegration-redox-decolorization, deodorization and detoxification-deep air flotation-deep flocculation. Item function. Its advent is a major technological change in domestic wastewater treatment.
With the advent of this technology, wastewater treatment has changed from complex to simple, from impossible to possible, from non-improvable biochemical to smooth biochemical advancement. In recent decades, many users have used chemical Fenton reagents to treat wastewater. As a result, COD has been reduced, and forced biochemicals have been avoided. However, it has caused extremely high operating costs and cannot be continuously operated. It is difficult to promote chemical Fenton. application. The electric Fenton technology developed by our company not only greatly reduces operating costs, but also enables continuous operation. And make the COD degradation rate reach 60% -80%, making the treatment of organic wastewater a breeze!
Biochemical treatment has made historical contributions, but the enzyme conversion capacity is limited, and it is powerless to high COD, high ammonia nitrogen, high phosphorus and so on. Practice has proved that the use of high-frequency electrolysis + biochemistry not only enables biochemistry to continue to play a role, but also enables various indicators to reach surface water class IV standards.
2. Governance process and principle:
The wastewater enters the regulating tank first. After the self-priming pump is started, the wastewater enters the super-redox generating device through the flowmeter. Under the action of a powerful high-frequency DC electric field, the technology of deflection and tumbling is used to optimize the electric field technology, which immediately produces five powerful functions: Cutting disintegration-redox-decolorization, deodorization and detoxification-deep air flotation-deep flocculation, this is due to the original ecological hydrogen ions, oxygen ions, hydroxide ions, iron The number of ions generated increases by 10,000 levels, and at the same time, the molecules of the pollution factor are constantly disintegrated and cut. Under the condition of electro-Fenton, the direct or indirect reaction of redox is also increased by 10,000 levels. In this way, the stubborn pollution factor It is also rapidly degraded. Depending on the nature of different pollution factors, fillers and oxidants, coagulants, and precipitants can be selectively added to the device to control the pH range of the inlet and outlet water and create more sufficient and necessary conditions for super-redox reactions. A variety of heavy metal ions can be removed together, and the treated wastewater reaches the standard of Table 3 for electroplating pollutant discharge. The treated water is clear and transparent. The water can be used as reclaimed water or recycled. For difficult-to-degrade organic wastewater, the use of electric Fenton technology not only greatly reduces COD, but also removes phosphorus and ammonia nitrogen in one go to reach the standard of the pipe network. If it enters the biochemical A / O system, it can meet the national surface water category IV standard , That is, COD <30mg / L.
Third, the basic characteristics of the governance process:
⒈In principle, this process is used with little or no medicine. Depending on the status of wastewater, MYS (pulse electroflocculation) or CYH (super strong redox electro-Fenton method) can be used to achieve the purpose of wastewater treatment.
⒉Not only reduces COD greatly, improves the hydrolytic acidification ability, but also has a good phosphorus removal effect (oxidize organic phosphorus to inorganic phosphorus and oxidize partial phosphorus to normal phosphorus to degrade); good ammonia nitrogen removal effect (decomposable, oxidizable, airborne, so that Ammonia nitrogen is decomposed, and organic nitrogen is oxidized to inorganic nitrogen to degrade it.) Desalination effect is good (with excellent decomposition and replacement effect).
工艺 The process has a small footprint, saves investment, is easy to manage and maintain, and has low operating costs. The key parts are imported original parts, and the service life of the host is more than eight years.
的 The advent of this technology has made the upgrading and transformation of water treatment plants a reality. Using this technology, the original treatment is unchanged, and the drainage can reach the surface water Category IV standard, which is two grades higher than the Grade A standard.
