Water pollution has become one of the important environmental issues worldwide, and

innovation in water treatment technology is crucial for human health and ecological environment

protection.The current water bodies contain a large amount of complex and difficult to degrade

pollutants, such as urine, antibiotics, heavy metal ions, bacteria,trace organic matter, etc.,

which greatly threaten the ecosystem and public health.Traditional water treatment methods,

such as adsorption,biodegradation,and chemical precipitation, have a certain ability to remove

pollutants, but there are still limitations in treating urine, antibiotics, bacteria, and trace organic

pollutants. In situ electrochemical technology, advanced oxidation processes(AOPs).and

photocatalytic technology have gradually become key means to address this challenge.In terms

of urine treatment, traditional techniques often struggle to cope with high concentrations of

organic matter and complex components. We will focus on researching how to convert waste

into valuable products and establish a closed-loop system for production,utilization, and

recycling, providing scalable solutions for large-scale urine treatment.
