Application of ozone advanced oxidation in printing and dyeing wastewater

With the acceleration of industrialization and urbanization, the printing and dyeing industry, as a traditional heavy industry, has always been one of the industries with serious environmental pollution. The large amount of wastewater generated by the printing and dyeing process contains a large amount of harmful components such as organic matter, pigments, and toxic metal ions. Direct discharge into the environment will cause serious water pollution. Therefore, printing and dyeing wastewater treatment has always been an urgent problem to be solved.

In the field of printing and dyeing wastewater treatment, ozone advanced oxidation technology is a widely used and efficient treatment technology. Ozone is a strong oxidant. In an advanced oxidation system, it can degrade organic matter into CO2 and H2O, and can effectively remove harmful components such as color and toxic metal ions in wastewater to purify water quality. Below we will introduce in detail the application of ozone advanced oxidation in printing and dyeing wastewater treatment.

First of all, ozone advanced oxidation technology is efficient and fast. In the ozone oxidation system, ozone molecules can quickly oxidize with harmful components such as organic matter, pigments, and toxic metal ions in organic wastewater, degrading them into harmless substances. Compared with traditional wastewater treatment methods, ozone advanced oxidation technology has obvious advantages in treatment efficiency, greatly shortening wastewater treatment time and improving wastewater treatment effects.

In addition, ozone advanced oxidation technology also has the characteristics of green and environmental protection. Compared with traditional wastewater treatment methods, ozone advanced oxidation technology does not require the addition of chemicals and does not cause secondary pollution problems. In addition, the products of the ozone oxidation reaction are mainly CO2 and H2O, which does not cause any pollution to the environment and is in line with the concept of green environmental protection.
