This design uses the hydrolytic acidificationcontact oxidation process to remove the anic matter, all kinds of pollutants in the refined cotton wastewater.Hydrolytic Acidification contact oxidation process has low energy consumption, will be able to greatly improve the wastewater biodegradability, resulting in less sludge characteristics, hydrolytic acidification process is part of the process of anaerobic fermentation, which changes the large molecules into small molecules of anic matter substances, increased the biodegradability of wastewater, and acid production in the acidification stage, the response in favor of the next stage of
