Underground printing and dyeing wastewater treatment

1. Stable operation, able to meet effluent requirements, mature process, and successful operating experience. The physical and chemical treatment tank is responsible for removing some organic matter, while the biochemical tank completes the degradation of ammonia nitrogen and organic matter.
2. There is physical and chemical processing control, which can resist impact loads. Sludge has a certain degree of stability and does not require anaerobic digestion treatment.
3. The aeration adopts blast aeration, equipped with an efficient aeration system that is evenly distributed at the bottom of the tank, with high power efficiency, low energy consumption, and less land occupation.
4. The requirement for automation level is relatively low, and the operation and management are simple and convenient.
5. Relatively small footprint and low investment.
Technology of Underground Wool Textile Printing and Dyeing Wastewater Treatment Equipment
Process description: The buried wool textile printing and dyeing wastewater in the workshop of the factory is collected through the pipeline network and enters the wastewater treatment system. After being intercepted by the grid, it enters the aeration regulating tank to adjust the water quality and quantity. The sewage pump lifts the wool textile printing and dyeing wastewater to the hydrolysis acidification tank. Under the action of anaerobic microorganisms, the large molecular organic matter in the wool textile printing and dyeing wastewater is decomposed into small molecular organic matter, improving the biodegradability of water quality and effectively removing water color. Facilitating subsequent aerobic treatment. Under the action of aerobic microorganisms, organic matter in textile printing and dyeing wastewater is decomposed into water and CO2 to further degrade the organic matter in the water. After further treatment of the wool textile printing and dyeing wastewater in the sedimentation tank, the effluent enters the decolorization tank, and the decolorization treatment ensures that the wastewater meets the discharge standards. After sedimentation, some of the sludge is returned to the integrated equipment tank. The remaining sludge is pumped into the sludge concentration tank by the sludge pump, and after concentration and volume reduction treatment, the sludge is pumped into the plate and frame filter press by the sludge pump for dewatering treatment. After treatment, the sludge is dried and transported for disposal.
