Ozone generator for printing and dyeing wastewater treatment

Due to the strong oxidizing effect of reactive oxygen species, it is a strong bleaching agent and can quickly and effectively eliminate various odors in the air and water.

Brief description of the composition of printing and dyeing wastewater

BOD: Between 200~800mg/L, this data is not only related to the raw materials, but also to the recycling of water in the production process. Using less water results in higher BOD, usually averaging between 300~500mg/L.

COD: between 800~1200mg/L, with an average of 1000mg/L. COD/BOD: The ratio of COD to BOD, the higher the value, the less likely the wastewater is to be biologically treated, and the lower the value, the more susceptible it is to biodegradation. Generally, the COD/BOD value of dyeing and finishing wastewater is adjusted between 1 and 5 to facilitate biological treatment.

SS: Usually, dyeing and finishing wastewater can be significantly reduced in operation, and filtration can reduce the production process from approximately 100mg/L to 75-50mg/L. Fats and lubricants: Fats and lubricants have a relatively low content of about 40mg/L during the weaving process of cellulose fibers, while they are higher on wool fibers.

Temperature: The temperature of dyeing and finishing wastewater is determined by the refining, bleaching, and dyeing processes, with an average temperature of 60-70 ℃.

Color: The color of dyeing and finishing wastewater comes from dyes, and the color varies depending on the type and form of dyes. Generally ranging from 800 to 15000 APHA chromaticity.

Sulfide content: The average is 0.1mg/L.

Metal content: The average is 0.11mg/L or less, mainly from dyes, and there are significant differences in the choice of dyes.

Phenol content: The average is 0.5mg/L, and there are significant differences due to the use of different additives.

Ozone generator function and application

Sterilization: It can quickly and effectively reduce and eliminate viruses and bacteria in the air and water. According to experimental reports from academic institutions, the concentration of reactive oxygen species in water is 0.05ppm, and after treatment for ten to ten minutes, the bacterial killing rate is over 99%.

Detoxification: Due to the development of industry and commerce and the enjoyment of high material civilization, there are various harmful substances to the human body everywhere during childbirth, such as carbon monoxide, pesticides, heavy metals, fertilizers, organic matter, odors, pigments, etc. After ozone treatment, they will be decomposed into safe substances that are harmless to the human body.

Preservation: The United States, Japan, and European countries have extensively applied ozone to the storage of various foods, which can extend the storage period of food and reduce spoilage rates, thereby reducing losses and improving quality.

Bleach: Due to the strong oxidizing effect of ozone, it has a strong bleaching agent and can be used in laundry, food, and wastewater treatment.

Deodorization: Due to the strong oxidative decomposition ability of ozone, it can quickly and effectively eliminate various odors in the air and water

Drinking water treatment: sterilization, disinfection and purification of purified water, mineral water, tap water, etc.

Wastewater treatment: oxidation, decolorization, sterilization and disinfection of domestic sewage, chemical sewage, medical sewage, etc.

Swimming pool water circulation treatment: (oxidation of harmful substances, removal of sweat left by the human body, etc.)

Medical applications (sterilization and disinfection of operating rooms, sterilization and disinfection of treatment rooms, sterilization and disinfection of patient bedding, application of ozone water in dentistry, application of ozone water in gynecological treatment, application of ozone water in promoting wound healing, etc.)

Surface disinfection and sterilization of items (processing tools in food factories, packaging containers for cosmetics, etc.) Home and public place treatment (sterilization, disinfection and purification of homes, schools, hotels, offices, leisure and cultural places, and daily necessities, removal of residual pesticides, etc.)
