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.
The advantages of printing and dyeing sewage treatment equipment:
- The processing equipment is made of carbon steel anti-corrosion treatment or stainless steel components, which are spliced and assembled on site. It is light in weight, easy to transport and easy to install.
- It is placed below the surface, and the surface above the equipment can be used as greening or other land, without the need for building, heating and heat preservation. The integration of the system is realized to the greatest extent, and the floor space is reduced.
- No pollution, no noise, no peculiar smell, reduce secondary pollution
- It is not limited by the amount of sewage, flexible and can be used individually or in combination.
- The entire equipment processing system is equipped with a fully automatic electrical control system and equipment failure alarm system, which is safe and reliable in operation. Usually, there is no need for special personnel to manage it. It only needs to maintain and maintain the equipment in a timely manner, and the management cost is small.
- The biggest feature is that the sewage treatment project can be arranged into a landscape. If the integrated equipment is buried underground, the water output effect is good, and the surface greening rate can reach more than 90%. If special iconic tree species or lawns that are cold-resistant and water-loving are used, a water treatment landscape integrating streams, fountains, ponds and fish ponds will be formed. , turning the turbid into a clear spring, not only treats the sewage but also beautifies the environment, and satisfies people’s desire to live by mountains and rivers.
