Relevant technical situation at home and abroad


The environmental friendliness of the products was qualitatively predicted according to the raw materials used for the production of leather chemicals. Germany has studied the biodegradability of tanning fatliquors.



Research and development contents


Characterization and standardization of biochemical activity of activated sludge


Degradation of tannery chemicals by activated sludge and standardization of testing methods


Evaluation standards and methods for biodegradation of different tannery chemicals



innovation point


For the first time, we systematically studied the biodegradability of tannery and chemical materials, and established a standard method and an evaluation index system that could be used to objectively evaluate the environmental friendliness of tannery chemicals.
