Abstract:
A case of Shantou Chaoyang textile printing and dyeing environmental protection comprehensive treatment center was introduced. The hydrolytic acidification process was used in the pretreatment stage to improve the biodegradability of wastewater, increase the removal rate of SS by primary treatment, and regulate the water quality and quantity. The principle, selection and application form of hydrolytic acidification process are further analyzed. The EBOTM up-flow hydrolytic acidification process and its advantages are mainly introduced. Meanwhile, the process flow of the plant is introduced, and the design parameters of the up-flow hydrolytic acidification tank are clarified. The commissioning operation shows that the hydrolytic acidification tank has good treatment effect on refractory wastewater.
