A wastewater aeration system injects air into sewage through aeration equipment to increase dissolved oxygen in water, creating favorable conditions for aerobic microorganisms to degrade pollutants. It is widely applied in various industries generating organic wastewater, as listed below:
1. Food Processing Industry
Meat processing plants, grain processing, fruit and vegetable processing, beverage brewing, starch processing, etc. The wastewater features high organic concentration. The aeration system supplies oxygen for activated sludge processes to degrade pollutants such as proteins, carbohydrates and grease.
2. Slaughter Industry
Livestock and poultry slaughterhouses and meat deep-processing enterprises. The wastewater contains a large amount of blood water, grease and protein. Aeration serves as the core unit in the biochemical treatment section to effectively reduce COD and BOD.
3. Chemical and Fine Chemical Industry
Manufacturers of fine chemicals, coatings, resins and daily chemicals. It is used to treat biodegradable organic wastewater and degrade organic pollutants together with biochemical processes.
4. Electroplating and Surface Treatment Industry
Production lines for electroplating, anodizing and metal cleaning. Aeration can oxidize part of reductive pollutants in the pretreatment stage and be applied in biochemical treatment. It also realizes mixing and stirring to prevent sludge sedimentation.
5. Paper-making Industry
Pulp and paper manufacturers. It treats intermediate wastewater and white water from paper machines, degrading organics such as lignin and carbohydrates and reducing BOD and COD.
6. Municipal Sewage
Urban domestic sewage treatment plants. The aeration system is the core of activated sludge processes and contact oxidation processes for domestic sewage treatment.
7. Pharmaceutical Industry
Producers of antibiotics, active pharmaceutical ingredients and Chinese patent medicines. It treats high-concentration pharmaceutical organic wastewater and supplies oxygen for aerobic biochemical reactions.
8. Breeding Industry
Large-scale livestock and poultry farms. It treats manure wastewater and degrades high-concentration organic matter from manure and urine.
9. Printing and Dyeing Textile Industry
Textile printing, dyeing and chemical fiber enterprises. It is used in the biochemical treatment of printing and dyeing wastewater to degrade organic substances including size, dye additives and auxiliaries.
