2025 IE expo Shanghai   At this exhibition, we showcased our portfolio of most competitive core product series, which became a major focus for on-site professional audiences.   The Intelligent Sodium Hypochlorite Generator, with its unique advantages of "using salt to replace chlorine, ensuring safety and high efficiency," attracted numerous visitors, including representatives from municipal waterworks, wastewater treatment plants, swimming pools, and rural safe drinking water projects. Its convenience and reliability were demonstrated vividly to clients.   The Efficient UV Disinfection System, known for its green operation and zero secondary pollution, became a key point of interest for many professionals from sectors such as wastewater treatment, food and beverage, electronics and semiconductors, and medical institutions. They engaged in in-depth discussions with our engineers regarding details such as guaranteed UV dosage and intelligent cleaning mechanisms.     The Advanced Oxidation Process (AOP) Wastewater Treatment System, a powerful solution for tackling refractory wastewater, emerged as a technical highlight of the exhibition. Many enterprise representatives and technical experts from the chemical, pharmaceutical, printing and dyeing, and pesticide wastewater treatment industries brought actual water sample data to jointly analyze feasibility and explore customized solutions.       Every in-depth discussion with a client holds the potential for a significant collaborative project. This exhibition has enabled us to initially identify multiple highly promising cooperation directions:   Municipal Sector: Reached preliminary consensus on technical proposals with a major water group for retrofitting disinfection processes in older water plants (replacing liquid chlorine), with follow-up site visits planned.   Industrial Sector: Established intentions for pilot testing cooperation with several fine chemical and pharmaceutical companies to address their challenges in pretreating high-concentration, highly toxic wastewater using advanced oxidation technology.   Strategic Partnerships: Explored models for strategic procurement agreements and technology bundling with leading domestic Environmental Engineering Contractors (EPCs), aiming to jointly develop more competitive integrated solutions. --------------占位---------------

The significance and role of ultraviolet disinfection in water treatment With economic development and improved living standards, the government and the public are increasingly prioritizing drinking water safety. my country's drinking water quality standards have undergone several revisions in recent years. The latest "Standard for Drinking Water Quality" (GB 5749-2022) sets higher safety requirements for drinking water quality, particularly regarding disinfection byproducts and upper limits for residual chlorine, which pose certain challenges to traditional chlorine disinfection processes. Consequently, cities such as Shanghai, Shenzhen, Suzhou, and Fuzhou have also established more stringent targets or local standards for high-quality or premium drinking water. Ultraviolet disinfection, as a physical disinfection method, has become an important option for improving water supply safety under these new conditions due to its broad-spectrum bactericidal properties, the absence of chemical agents, and the generation of no disinfection byproducts.   Chlorine-resistant microorganisms may exist in drinking water. In addition to well-known chlorine-resistant microorganisms such as Giardia lamblia and Cryptosporidium, studies have shown that chlorine-resistant microorganisms such as Sphingomonas, Pseudomonas, Cereus, Acinetobacter haemolyticus, Bacillus fuscae, Bacillus alvei, Legionella, and Thiophages are commonly found in the outlet water and water supply networks of Chinese water plants. Some of these chlorine-resistant microorganisms are opportunistic pathogens. Effectively inactivating these chlorine-resistant microorganisms requires a significant increase in the CT value of chlorine, making chlorine disinfection uneconomical or even impossible to implement, and significantly increasing the risk of excessive disinfection byproducts. Strictly speaking, the traditional single-unit chlorine disinfection model presents a safety vulnerability. Once a chlorine disinfection unit fails, the water plant's microbial safety barrier is completely lost. Therefore, from the perspectives of biological and chemical safety, a multi-barrier disinfection strategy and concept is essential for improving water supply safety. This concept has now been widely accepted and practiced in urban water plants in North America and the European Union. Ultraviolet disinfection has become an indispensable and even a key part of the combined disinfection method because it can meet both biological and chemical safety requirements.   Current Application of Ultraviolet Disinfection in my country's Water Treatment In recent years, the multi-barrier disinfection concept and ultraviolet disinfection technology have gradually gained recognition and promotion in my country's water supply sector, with initial application in urban water plants. According to incomplete statistics, over 60 large-scale water plants in China currently employ ultraviolet disinfection processes, with a tr...

The Datong Yudong Wastewater Treatment Plant Project Background   The Datong Yudong Wastewater Treatment Plant has a treatment capacity of 100,000 cubic meters per day. Its wastewater primarily consists of pharmaceutical wastewater and pharmaceutical intermediate wastewater, characterized by complex composition, high organic content, high toxicity, dark color, high salinity, and difficulty in degradation. After pre-treatment at the pharmaceutical plant, the residual effluent from upstream water primarily consists of difficult-to-biodegrade macromolecules and antibiotics, which exhibit significant bioinhibition, making it a typical example of difficult-to-biodegrade industrial wastewater.   The first phase of the project initially employed an ozone oxidation process, but after initial implementation, it did not achieve the desired treatment results. Subsequently, a fluidized bed Fenton process was adopted; the second phase will utilize a magnetic Fenton process.   Recently, the magnetic Fenton process section of the Datong Yudong Wastewater Treatment Plant renovation and expansion project, undertaken by Guangzhou Jinchuan, has successfully commenced operation.   The Phase 1 project used a fluidized bed Fenton system, which presented the following operational and maintenance challenges:   1. High reagent consumption;   2. High power consumption and failure rate of the reflux pump;   3. Regular packing replacement required;   4. The reactor was prone to clogging, requiring frequent unclogging of the water distributor within the tower, placing a heavy workload on on-site operators;   5. Long process chain: The Fenton effluent was approximately 47 mg/L, requiring subsequent sand and carbon filtration to achieve a final effluent below 40 mg/L;   6. Annual maintenance costs exceeded 2 million RMB;     The phase 2 project utilized a magnetic Fenton system. Compared to a fluidized bed Fenton system, this system eliminates the need for a reflux pump, reducing the number of pipes on site and keeping the floor clean and tidy. There is no need to overhaul the reflux pump, replace packing, or unclog the water distributor within the tower, preventing reactor compaction and blockage, significantly reducing the workload for on-site operators.   Jinchuan Super Cheap Magnetic Fenton: Technology from Germany   Fluidized bed Fenton: COD after biochemical treatment is mostly extremely difficult to degrade. Dissolved organic matter (DOD) is surrounded by a large number of water molecules, making it difficult for hydroxyl radicals to reach the COD. A saturation attack method is used to deoxidize the COD with H₂O₂ at concentrations several times the COD level. This results in extremely high H₂O₂ consumption. In actual projects, this results in high hydrogen peroxide dosages and the need for subsequent degassing tanks.   Super Cheap Magnetic Fenton Technology: Wastewater is first magnetized, alteri...
