What are the benefits of photochemical advanced oxidation processes in salt recovery pretreatment?
2025-07-28

Photochemical advanced oxidation processes (such as UV/H₂O₂ and UV/O₃/H₂O₂) can effectively remove organic pollutants and improve water quality during salt recovery pretreatment, providing clean conditions for subsequent salt recovery, increasing salt purity, and improving evaporation efficiency. Their green characteristics (oxidation products are water and oxygen) and their ability to degrade complex organic matter contribute to achieving zero wastewater discharge and resource utilization.
What are the principles and advantages of photochemical advanced oxidation PAO for cyanide removal?
2025-07-28

PAO uses ultraviolet light to react with an oxidant (such as H₂O₂) to generate hydroxyl radicals (·OH). These strong oxidizing properties can break down the molecular structure of cyanide, converting it into non-toxic carbon dioxide, nitrogen, or ammonium salts. The advantages of this technology are:
1) It efficiently degrades difficult-to-treat inorganic and organic cyanides (such as metal cyanide complexes);
2) It is a thorough treatment process, reducing secondary pollution;
3) It is applicable to a variety of industrial wastewaters (such as those from electroplating and chemical industries), and is particularly effective against highly toxic and difficult-to-degrade pollutants.
What are advantages of photochemical AOPS for pre-treating wastewater with a COD below 50,000 mg/L?
2025-07-28

For pre-treating wastewater with a COD below 50,000 mg/L, photochemical advanced oxidation systems offer lower investment and operating costs, simpler operation and maintenance, longer service life, and lower component replacement costs. Furthermore, they are unaffected by high salt loads, exhibit less corrosive equipment, and reduce safety risks. Furthermore, they offer mild operating conditions, flexible startup and shutdown, and a compact footprint.
What are the benefits of photochemical AOPs for difficult-to-treat wastewater?
2025-07-28

Photochemical advanced oxidation processes (AOPs) use ultraviolet light to activate oxidants (such as H₂O₂ and O₃) to generate hydroxyl radicals (·OH). This effectively degrades refractory organic matter, improves the biodegradability (B/C ratio) of wastewater, removes toxic substances (such as fluoride and antibiotics), and achieves advanced treatment without secondary pollution. This technology is suitable for both pretreatment and advanced treatment of high-salinity, highly toxic, and difficult-to-biodegrade wastewater, and is particularly widely used in the pharmaceutical, petrochemical, and electronics industries.
What wastewater industries are suitable for photochemical advanced oxidation processes?
2025-07-28

Photochemical advanced oxidation processes are suitable for treating high-concentration, difficult-to-degrade, and highly toxic wastewater from industries such as pharmaceuticals, pesticides, petrochemicals, metallurgy, chemicals, plastics, papermaking, textiles, printing and dyeing, and electronics. These wastewaters contain pollutants such as phenols, aromatic compounds, antibiotics, hormones, organohalogens, and polycyclic aromatic hydrocarbons. They are particularly effective against wastewater with poor biodegradability, high COD, and strong bioinhibition.
How does the ONYX photochemical AOPs ensure it is unaffected by water color and turbidity?
2025-07-28

The ONYX photochemical advanced oxidation process utilizes ingenious flow channel design and turbulent flow pattern control, combined with CFD simulation to optimize reaction conditions and prevent waste accumulation within the pipeline. A UV reflective layer enhances transmittance, ensuring uniform UV distribution and efficient utilization, effectively addressing water color and turbidity interference.
What are the technical advantages of photochemical advanced oxidation?
2025-07-28

Photochemical advanced oxidation technology (UV-AOPs) offers advantages such as efficient degradation of refractory organic matter, production of highly oxidizing hydroxyl radicals (·OH), zero secondary pollution, a wide range of treatment options (such as pharmaceutical, petrochemical, and pesticide wastewater), and mild operating conditions. It also features automated control, low operating costs, and strong system integration.
How does photochemical UV advanced oxidation work?
2025-07-28

Photochemical (UV) advanced oxidation technology uses ultraviolet light to excite oxidants (such as H₂O₂ and O₃) to generate highly oxidizing hydroxyl radicals (-OH). With a redox potential as high as 2.8V, these radicals can indiscriminately attack the chemical bonds of organic pollutants, effectively degrading and mineralizing them into CO₂ and H₂O. This process combines direct photolysis with indirect oxidation, making it suitable for treating difficult-to-degrade wastewater.
The device's automatic cleaning system indicates an abnormality. How can I correct the prob
2025-07-28

If the device's automatic cleaning system indicates an abnormality, follow these steps to troubleshoot:
1. Check whether the UV intensity sensor's signal is abnormal due to contamination in the quartz sleeve. Clean the sleeve and retest.
2. Determine whether the motor cleaning function is malfunctioning due to a damaged fuse or motor failure. Replace the fuse or motor and clean any foreign objects inside the sterilizer.
3. Foreign object blockage: Clear any foreign objects from inside the sterilizer and ensure unimpeded water flow.
4. Wiring and power supply: Check the power connections and fuses to eliminate any short circuits or open circuits.
What does operator training cover?
2025-07-28

This training covers equipment principles, daily operations, troubleshooting, and safety precautions. It provides both theoretical and practical training, as well as assessment and certification.
