Ozone generator for electroplating wastewater treatment

The oxidation ability of ozone is second only to fluorine in terms of its oxidation-reduction potential, and this characteristic is mainly used in its applications. Ozone and ferrous Mn2+ 、 Sulfides, sulfur, chlorine, and other inorganic substances undergo reactions. Ozone mainly utilizes its strong oxidizing properties in the treatment of electroplating wastewater.

The sources of electroplating wastewater are generally:

(1) Plating cleaning water;(2) Waste electroplating solution;(3) Other wastewater, including flushing workshop floors, scrubbing electrode washing water, ventilation equipment condensate water, as well as various tank liquids and drainage caused by leakage or improper operation management of plating tanks, such as "running, emitting, dripping, and leaking";(4) Equipment cooling water, during use, is not contaminated except for temperature rise.

The quality and quantity of electroplating wastewater are related to factors such as the process conditions, production load, operational management, and water use methods of electroplating production. The water quality of electroplating wastewater is complex and its composition is difficult to control. It contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, silver, etc. Some of them are highly toxic substances that are carcinogenic, teratogenic, and mutagenic.

The oxidation ability of ozone is second only to fluorine in terms of its oxidation-reduction potential, and this characteristic is mainly used in its applications. Ozone and ferrous Mn2+ 、 Sulfides, sulfur, chlorine, and other inorganic substances undergo reactions. Ozone can also undergo redox reactions with organic compounds such as alkenes, amines, phenols, polycyclic aromatic hydrocarbons, alcohols, aldehydes, alkanes, proteins, etc. When ozone is sufficient, it can oxidize organic compounds into carbon dioxide and water.

Ozone mainly utilizes its strong oxidizing properties in the treatment of electroplating wastewater. Due to the varying composition of electroplating wastewater, the actual amount of ozone used should be based on the actual water quality. This equipment is for reference only.

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 reactive oxygen species, it is a strong bleaching agent and can be used in laundry, food, and wastewater treatment.

Deodorization: Due to the strong oxidative decomposition ability of reactive oxygen species, it can quickly and effectively eliminate various odors in the air and water. Product application:

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: oxidizes harmful substances, removes 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, home and public places (sterilization, disinfection and purification of homes, schools, hotels, offices, leisure and cultural places, and daily necessities, removal of residual pesticides, etc.).
