Water is the source of life. The 70th anniversary of the founding of the People's Republic of China, especially in the 40 years since the reform and opening up, China's economy has shown rapid development. At the same time, pollution problems have become increasingly prominent, and the ecological environment has been greatly damaged. As a result, rivers and lakes have been seriously polluted, and groundwater has been severely impacted. This year's issue of the three ministries and commissions  No. 52 requires that urban sewage treatment be upgraded and enhanced within three years. The state is continuously strengthening environmental protection inspections and continuously improving environmental protection emission standards in order to curb environmental degradation.
At present, due to the deterioration of the ecological environment, mainly due to the large amount of pollution, and the structure of pollution factors is becoming more and more complex, which makes handling more difficult. All parts of the country not only require stable compliance, but also require upgrading. In the face of the new environmental protection situation, wastewater treatment is more The use of chemical, physical, ultrafiltration, micro-electrolysis, electrodialysis, reverse osmosis, biochemical methods, multi-effect evaporators, etc., alone or in combination, makes the wastewater treatment process more and more complicated, the operating costs are higher and higher, and the area Increasingly larger and higher investment costs. The key problem is that the molecular structure of the pollution factor has not been touched. It is more effective and less effective. Facing environmental requirements and the need for environmental protection, Liang Fengming (Senior Chairman of Xinxiang Tiansheng Environmental Engineering Equipment Co., Ltd. Engineer), developed the "super-redox wastewater treatment device". Obtained more than 20 energy-saving and environmental protection patents, reaching the international leading level. Its advent is a major technological change in domestic wastewater treatment.
"Super strong redox wastewater treatment device" is applicable to the treatment of various heavy metals and organic wastewater, involving industries such as electroplating, coking, mining, smelting, chemical industry, medicine, pesticides, batteries, agricultural product processing, garbage permeate, dyes, and black smelly water And other difficult-to-treat 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.
The technology officially passed the national science and technology evaluation in August 2016, and the conclusion “reached the international advanced level”. He has won several provincial and ministerial awards and patent gold awards, China's outstanding new product titles, international gold awards, and "China's environmentally-friendly product quality trusted brand". In August 2018, it won the "Environmental Science and Technology Innovation and Practical Achievement Award" of the Ministry of Environmental Protection and Environmental Science Association, and was included in the 2018 National Environmental Science and Technology Recommendation Directory.
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 biochemical can be reluctantly added. However, the operation cost is extremely high, and continuous operation cannot be performed. It is difficult to promote the application of chemical Fenton. . The electric Fenton technology developed by the 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 easy! Traditional 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 allows various indicators to reach surface water Category IV standards.
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 hydrogen ion, oxygen ion, hydrogen The generation of oxygen ions and ferrous ions increased by tens of thousands, and at the same time, the molecules of pollution factors were constantly disintegrated and cut. Because of the electric Fenton condition, the generated hydroxyl radicals [· OH] also increased by tens of thousands. In this way, even stubborn pollution factors will be quickly disintegrated and oxidized. Depending on the nature of different pollution factors, the device can also selectively change the electrode material and oxidant, properly add oxidants and coagulants, control the pH value range of the inlet and outlet water, and create a more sufficient and necessary condition for the super-redox reaction. . A variety of heavy metal ions can be removed together, and the treated wastewater meets the standards in Table 3 of the "Emission Standards for Electroplating Pollutants". For difficult-to-degrade organic wastewater, the use of electric Fenton technology not only greatly reduces COD, but also removes phosphorus, desalination, and ammonia nitrogen in one go to reach the standard of the pipeline network. If it enters the biochemical A / O system, it can reach the national surface water Ⅳ Class standard, the treated water is clear and transparent, colorless and odorless.
Basic characteristics of plant treatment process
⒈In principle, this process is used with little or no medicine. Depending on the status of the wastewater, MYS (high frequency electroflocculation) or CYH (high frequency electrical Fenton) 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 (which can oxidize organic phosphorus to inorganic phosphorus and oxidize partial phosphorus to normal phosphorus to degrade it); and has a good effect of removing ammonia nitrogen (decomposable, oxidizable, airborne, and Ammonia nitrogen is decomposed, and organic nitrogen is oxidized to inorganic nitrogen to degrade it); the desalination effect is good (have excellent decomposition, flocculation, adsorption, and cooperation).
工艺 The process has a small footprint, saves investment, is easy to manage and maintain, and has low operating costs. The key components are imported original parts (Japan's Mitsubishi, Germany's Siemens, and the United States ON), and the mainframe has a service life of more than eight years.
的 The advent of this process has made the national water treatment plant standardization and transformation 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.
High-frequency electrolytic equipment and pool floor plan (schematic)
At present, water treatment processes are numerous and complicated, and fish-eye mixed beads increase treatment costs, increase investment costs, and increase floor space, placing a heavy burden on enterprises. Taking the current domestic water treatment plants as an example, if the daily treatment capacity is 50,000 tons, the A / O process is used, the investment is 500 million yuan, the operating cost is 1.5 yuan per ton of water, about 50 management personnel, and the discharge standard is Class A .
Liang Fengming, Chairman of Tiansheng Environmental Protection, told us: The new water treatment plant using our company's "high-frequency electrolysis + contact oxidation method" has a daily treatment capacity of 50,000 tons, an investment of only 250 million yuan, and an operating cost of 0.8 yuan per ton of water. The management staff can reduce by 50%, and the discharge meets the Class IV standard of surface water. If our company's technology is used to upgrade the standard, the native system only retains the aerobic and anoxic sections, and the front-end high-frequency electrolytic device has an investment of only 125 million yuan, and the operating cost is 1 yuan per ton of water, which can reach surface water after treatment. Ⅳ standard. If you treat various heavy metal wastewater, the operating cost only needs 1.3 yuan / ton of water (among which, the electricity fee is 0.8 yuan / ton of water, the plate fee is 0.2 yuan / ton of water, and the drug fee is 0.3 yuan / ton of water), and the amount of sludge generated is small ( Dry sludge (3 kg / ton water), the investment is only 30% of the chemical method.
This year is the 70th anniversary of the founding of the People's Republic of China. Over the past 70 years, China's science and technology development has achieved world-renowned great achievements, confirming the unbreakable truth that science and technology thrive, nations thrive, and science and technology strengthen the country. The constant development of science and technology undertakings has dedicated youth and wisdom, and made tremendous contributions. Chairman Liang Fengming, senior engineer, graduated from Huazhong University of Science and Technology in nuclear physics and has been engaged in environmental protection for 33 years. He is a participant, builder and contributor in the development of environmental science and technology.
