Protect on the Printing and Dyeing Wastewater Treatment
Abstract:
Our country is the biggest country in the textile, printing and dyeing, and is also a major country of the industrial wastewater discharge in the textile, printing and dyeing industry. Printing and dyeing industry to achieve sustainable development are very necessary, do a printing and dyeing wastewater treatment design worth it. By reading foreign literature, the investigation found information printing and dyeing wastewater capacity, high color, complex, wastewater containing dyes, pulp, chemicals, fibers and inorganic impurities, difficult. The design of the Health COD, poor biodegradability, there is organic macromolecules, So design "Anaerobic-aerobic biochemical" as the mainstay of the current more mature biological treatment process. Acid hydrolysis through anaerobic degradation of biological degradability of small molecules under aerobic conditions to ensure the further degradation of organic matter through the use of Aeration delay the oxidation ditch method to remove BOD, COD, nitrogen and phosphorus removal, improve water quality impact of changes in load adaptability. then return to facilitate the anaerobic sludge digestion series of measures to deal with the wastewater reaches the prescribed emission standards completion of the design objectives.
