Testing Methods And Evaluation Criteria For Environmental Friendliness Of Tannery And Chemical Materials

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.
