With the rapid development of the industry and people's attention to environmental protection, wastewater treatment technology has become more and more important in industrial production. Especially for enterprises operating in production lines, how to achieve zero wastewater discharge has become an urgent issue.
Advanced oxidation technology is a method of degrading organic pollutants through redox reactions. This technology mainly converts organic matter into easy-to-handle inorganic matter by adding oxidants and catalysts, using photocatalysis, ozone oxidation or ozone hydroxide oxidation. This technology not only has high reactivity to organic pollutants, but also has a good suspended solids removal effect on wastewater, thus achieving the goal of zero discharge.
Membrane separation technology is a method of separating and purifying liquids or gases using special membrane materials. In the wastewater treatment of the production line, membrane separation technologies such as microfiltration, ultrafiltration, nanofiltration and reverse osmosis are mainly used. By adjusting the pore size and transmittance of the membrane, the suspended solids, particles and dissolved substances in the wastewater can be effectively removed, and the purification and utilization of water can be realized. At the same time, membrane separation technology can also be combined with other wastewater treatment technologies, such as biological treatment and chemical treatment, to improve the efficiency and comprehensive benefits of wastewater treatment.
In addition to advanced oxidation technology and membrane separation technology, other auxiliary technologies and means can also be used to achieve zero discharge of wastewater from production lines. For example, by optimizing the production process, the amount and nature of wastewater generation can be improved; Adopt reuse technology to reuse wastewater and reduce the demand for clean water; Strengthen the maintenance and management of wastewater treatment equipment to improve the treatment effect and operational stability.
