As clusters of modern industry, industrial parks, with their massive water consumption and complex wastewater composition, place dual pressures on the environment and resources. Therefore, centralized, advanced treatment and high-quality reuse of comprehensive industrial park wastewater is essential for ensuring sustainable regional economic development and ecological security.
Industrial park wastewater is highly heterogeneous and subject to dynamic fluctuations, driven by a "park-specific" approach. Furthermore, various industrial processes (such as boiler feed water, electronic ultrapure water, and pharmaceutical water) place extremely stringent quality requirements on recycled water, far exceeding conventional municipal recycled water standards.
Achieving the transformation from "wastewater" to high-quality "living water" requires a combination of advanced treatment technologies. Ultraviolet (UV) and ozone (O₃) technologies, with their unique advantages, have become a core link in the chain of advanced wastewater treatment and high-quality reuse in industrial parks.
UV-AOPs pretreatment clears the way for advanced purification.
Using chemical and biological methods in synergistic fashion, UVAOPs are ideal for treating organic wastewater that is difficult to degrade with biological treatment.
High-efficiency disinfection: Ensuring biosafety.
Disinfection is a key step in killing harmful pathogenic microorganisms in water and ensuring the biosafety of reused water:
· Ultraviolet (UV) disinfection: A physical disinfection method that produces no chemical byproducts and is also effective against viruses and chlorine-resistant Cryptosporidium, making it an environmentally friendly technology.
· Ozone (O₃) disinfection: Its strong oxidizing properties provide excellent disinfection effectiveness while also effectively removing color, odor, and some organic matter.
High-quality water final polishing treatment focuses on removing all dissolved salts (TDS), residual trace organic matter, and all particulates, producing high-purity water that meets specific industrial requirements.
Ultrafiltration (UF) + Nanofiltration (NF) / Reverse Osmosis (RO) + UV/H2O2 (UV/H2O2/O3) produces high-quality recycled water.
Zero Liquid Discharge (ZLD) is the ultimate vision of industrial water treatment, representing the complete realization of the circular economy. UV and ozone technologies are integrated throughout, playing irreplaceable roles in pretreatment, detoxification, efficient disinfection, and terminal trace organic control.
