| LEM microelectrolysis catalytic oxidation technology and products The core technology of LEM micro electrolytic catalytic oxidation is a new type of micro electrolytic filler. It is a multi-element catalytic oxidation filler developed by Long'antai Company aiming at the characteristics of current organic wastewater that are difficult to degrade and difficult to biodegrade. It has obtained a national invention patent and is the inventor of a new type of micro electrolytic filler in China. It is produced by using a multi metal alloy fusion catalyst and high temperature microporous activation technology, and belongs to a new type of addition type non binding micro electrolytic filler. Relying on the catalytic oxidation and reduction action of double free radicals, it can efficiently remove COD, reduce chromaticity, improve biodegradability, and achieve stable and lasting treatment effects. At the same time, it can avoid the phenomenon of filler passivation and hardening during operation. This filler is an important guarantee for the continuous reaction of the micro electrolysis double free radical catalytic system. Since the product was launched on the market, it has achieved good results in a large number of applications, and has received unanimous praise from customers. Technical Principles This process is mainly applied to leather and paper making wastewater, printing and dyeing wastewater, dye industry wastewater, pharmaceutical intermediate wastewater, petrochemical wastewater, coal chemical industry, coking, surface treatment wastewater, and other refractory high concentration wastewater. The catalytic system can destroy the structure of toxic pollutants that are decomposed and converted, improve the biodegradability of wastewater, and provide a sustainable role for subsequent biochemical treatment. |

| LCO ozone efficient catalytic oxidation technology and products LCO ozone efficient catalytic oxidation technology can effectively decompose and remove highly stable organic pollutants in water, reduce the mutagenic activity of water, and significantly improve the safety of factory water. The catalytic form is divided into two forms: homogeneous (micro ion slow release, liquid gas liquid) and heterogeneous (micro suspension peristaltic catalyst, solid gas liquid). The introduction of catalysts can enhance the mass transfer of O3 in water, improve the conversion rate of · OH, improve the utilization rate of O3, and reduce O/C, ensuring the overall decontamination effect of the oxidation system treatment unit, and significantly reduce investment and operating costs. At the same time, it improves the biodegradability of wastewater, providing a sustained effect for subsequent biochemical treatment. This process is mainly applied to the advanced treatment and standard upgrading process of municipal, chemical, and mixed wastewater treatment plants. The ozone catalytic system can oxidize and decompose refractory organic pollutants, breaking long chain molecules into short chain molecules, and breaking the chain into straight chains, so as to further degrade into non-toxic or low toxic small molecule substances, improving the biodegradability of wastewater. |

| LEC electrochemical multidimensional catalytic oxidation technology and products The LEC electrochemical multi-dimensional catalytic oxidation technology independently developed by Long'antai Environmental Protection is a promising treatment process gradually developed for the treatment of high-salt and high-concentration wastewater. A special coated catalytic electrode plate is used to directly or indirectly mineralize and degrade organic matters, ammonia nitrogen, total nitrogen, etc. in wastewater under the action of anode catalysis through an external DC power supply. At the same time, its strong oxidation action can also break the chain of long-chain organic matters in wastewater, achieving the destruction and degradation of organic matters. This process only consumes electrical energy, does not add any chemical agents, and has no secondary pollution; The reaction is carried out under normal temperature and pressure, and the operation is simple and flexible; The modular assembly of LEC electrochemical multi-dimensional catalytic oxidation technology can quickly achieve engineering applications, with a high degree of automation in system operation and no human operation burden. This process is mainly applied to high salt and high concentration wastewater such as heavy metal wastewater, cyanide containing wastewater, dye industry wastewater, garbage leachate, fine chemical wastewater, pharmaceutical intermediate wastewater, petrochemical wastewater, coal chemical industry, coking, coke wastewater, surface treatment wastewater, etc., with a COD removal rate of 50% - 90%. |

| Heterogeneous fenton catalytic oxidation technology and products Organic matter and hydrogen peroxide are diffused from the main body of the solution to the active site on the surface of the catalyst and adsorbed. Then, under the catalysis of the catalyst component, hydrogen peroxide is decomposed to produce ·OH, which leads to the free radical chain reaction to oxidize and degrade the organic matter. Finally, the degradation products are desorbed from the surface of the catalyst and diffused into the main body of the solution. The technology replaces the addition of traditional Fenton Central Asian iron ions, avoids the generation of a large amount of iron mud, prevents the generation of secondary pollution, and greatly improves the shortcomings of traditional Fenton. The process is mainly used in printing and dyeing wastewater, dye industry wastewater, landfill leachate, pharmaceutical wastewater, coal chemical wastewater, pesticide wastewater, emulsion wastewater and so on. |

| Dual-culture coupled nitrogen removal process and products The double-cultivation coupled nitrogen removal process is a new type of nitrogen removal process with great application prospects. The technical core of this process is the dual-cultivation coupled denitrification filler. There are two main forms of this process: one is to pass the pollutants through two systems in sequence, so that the two reactions occur sequentially; the other is to make two electron donors coexist in the same system, and in the same system Two dominant bacteria are mixedly cultured in the medium, and by regulating various environmental or water quality factors, the bacterial flora can coexist in the ecological niche, giving full play to the respective roles of the dominant bacterial flora, so that the two reactions can occur simultaneously. The dual-culture coupled nitrogen removal process can not only effectively improve the total nitrogen removal rate, avoid nitrite accumulation, control sulfate generation, but also reduce the consumption of organic carbon sources, balance pH, etc. This process is mainly applied to leather and paper making Printing and dyeing wastewater 、Landfill leachate 、 Coal chemical wastewater、 Emulsion wastewater、 Pesticide wastewater 、Pharmaceutical wastewater、Dye industry wastewater and so on. |
