[0002] Industrial wastewater treatment refers to the process of subjecting wastewater generated during industrial production to a series of physical, chemical, and biological treatments to remove harmful substances, reduce pollution loads, and ensure that it meets emission standards or is reusable. Industrial wastewater is diverse and complex in composition, and treatment methods vary by industry and pollutant type. To conserve water resources and reduce costs, more and more companies are implementing wastewater reuse technologies, reusing treated wastewater in production processes. Industrial wastewater also contains recyclable phenolic and ammonia compounds, which are valuable byproducts or raw materials in many industrial processes, such as the chemical, pharmaceutical, and oil refining industries.
