The first step when the wastewater comes in is pretreatment. Wuxi Jingbo Environmental Protection Technology Co., Ltd.'s Dyeing and Printing Industry Wastewater Treatment Equipment includes advanced oxidation equipment and a coagulation reaction tank. The advanced oxidation equipment is very powerful; it uses strong oxidants like ozone and Fenton's reagent to break down those complex, large-molecule organic pollutants that are difficult to decompose. This significantly reduces the water's color and a portion of the COD. In the coagulation reaction tank, chemicals are added to cause colloids and small suspended solids in the water to clump together into larger flocs, making subsequent treatment much easier – if this step isn't done well, the problems later on will be much greater.
After pretreatment, it's on to the main treatment stage. Our factory uses a combination of a hydrolysis acidification tank and a biological contact oxidation tank, which is particularly effective. The hydrolysis acidification tank first breaks down the large-molecule organic substances that microorganisms can't directly "eat" into smaller molecules, making it much easier for the microorganisms to process them later; the biological contact oxidation tank is continuously aerated to provide oxygen to the microorganisms, allowing these little guys to "eat" all the dissolved organic pollutants in the water. This is particularly suitable for dyeing and printing wastewater, and it shows that Wuxi Jingbo Environmental Protection Technology Co., Ltd. has real experience in process design.
The final step is advanced treatment, which allows the water to be reused. Our Dyeing and Printing Industry Wastewater Treatment Equipment includes a UF ultrafiltration system, an RO reverse osmosis system, an activated carbon filter, and a UV sterilizer. The UF and RO systems remove a lot of the salt from the water, and the treated water can be reused in dyeing and printing production, saving a lot of fresh water; the activated carbon filter further absorbs any remaining organic matter and color, and the UV sterilizer kills bacteria in the water, making it safe to use.

Furthermore, Jingbo's Dyeing and Printing Industry Wastewater Treatment Equipment is particularly flexible and can be adjusted according to the specific conditions of the dyeing and printing factory – for example, if the factory's wastewater has a strong color, a decolorization module can be added; if there are many difficult-to-decompose substances, a corresponding treatment module can be added.
The equipment is also self-controlling, eliminating the need for constant manual monitoring and adjustment, ensuring stable treatment results, and occupying a small footprint, making it ideal for dyeing and printing factories with limited space. With this equipment, dyeing and printing factories can meet discharge standards and establish a green corporate image. It must be said that Wuxi Jingbo Environmental Protection Technology Co., Ltd. truly has strong capabilities in industrial wastewater treatment.
