The objects of dye wastewater: printing and dyeing factories, clothing washing factories, garment factories, woolen factories, the main characteristics are: (1) high organic content, strong toxicity and difficult to biodegrade; (2) complex composition; (3) high chromaticity ; (4) The discharge volume is large and the treatment is difficult, the waste water is discharged intermittently, and the water quality and quantity change greatly with time.
The basic working principle of printing and dyeing sewage treatment equipment: the equipment uses the activated sludge method to achieve the purpose of purifying sewage. Its principle: use the life activities of anaerobic bacteria and aerobic bacteria to consume organic pollutants in sewage, and at the same time, biological flocs formed by microorganisms destabilize and flocculate suspended and colloidal organic pollutants, and adsorb on the surface of activated sludge. , degrade organic matter, and finally achieve the effect of purifying sewage.
