| 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. |

| 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. |

| Electrocatalytic reduction of total nitrogen removal processes and products The electrocatalytic reaction consists of two parts: catalytic oxidation at the anode and catalytic reduction at the cathode. The synergistic electrocatalytic reaction of the cathode and anode can simultaneously degrade ammonia nitrogen and nitrate nitrogen in the water to achieve the purpose of reducing total nitrogen. Cooperative electrocatalytic reactions between cathodes and anodes In the electrochemical denitrification process and hybrid systems, the active substances electrically generated on the anode surface can promote the efficiency of the entire electrocatalytic system and the N2 generation. As a common anionic species in water, chloride ions can participate in anodic reactions to form hypochlorous acid and hypochlorite ions. In the presence of hypochlorous acid, ammonium ions can be oxidized to N2. In the cathode area, nitrate radicals receive electrons on the cathode surface and are reduced to N2, achieving the effect of degrading nitrate nitrogen. Therefore, the use of cathode and anode collaborative electrocatalytic reactions to simultaneously achieve NO3 − reduction and NH4+ oxidation is an effective means to solve the excessive generation of NH4+ in some electrocatalytic nitrate reduction systems. This process is mainly applied toPrinting and dyeing wastewater，Pesticide wastewater，Coking wastewater，Pretreatment of high COD wastewater such as biopharmaceutical wastewater，Advanced treatment in water plants. |

| Nano heterogeneous catalytic oxidation technology As a Fenton-like technology, this catalytic oxidation technology has the same conditions as the conventional Fenton process, but the ferrous sulfate added is replaced by a nanoscale catalyst (LAT-NMF), which not only reduces the amount of iron in the water treatment system Dosing amount reduces solid waste production, while also reducing the introduction of sulfate ions and reducing the increase in salt content. The catalyst products developed by our company are mainly catalytic oxidation catalysts based on the nanoscale catalyst LAT-NMF system. This product has the characteristics of high density, easy separation, strong catalytic effect, and high catalytic efficiency, and can effectively improve the utilization efficiency of hydrogen peroxide. At the same time, because less catalyst is used, the production of solid waste is greatly reduced compared with conventional Fenton. It is an advanced oxidation technology with high catalytic efficiency, few secondary products, and environmental friendliness. |
