Wastewater mainly comes from prefabrication, tanning and other wet treatment parts. Tanning and depigmentation wastewater is a kind of heavy tanning wastewater.

In the leather industry, because the wet processing of leather factory is carried out in water, many leather chemicals are added into the water. The skin of raw materials in leather production can not completely absorb the chemical materials in water, and the absorption rate of some chemical raw materials is very low. For example, in the process of Liming and unhairing in leather production, the surfactant used for leather processing is discharged into the wastewater, which not only is difficult to remove, but also affects the growth of microorganisms; the heavy metal chromium is also used in the tanning process. After it was recycled, no one wanted to use it. It affects the quality of finished leather in tanning process, and when tannery sludge is discharged into the environment, it will not recover hazardous waste.

Due to the difference of raw leather (cow leather, sheep leather, pig leather), processing technology and finished leather (shoe leather, garment leather, sofa leather, bag leather, etc.), tannery wastewater produced by tannery is also different. The difference of wastewater quality is very big, especially the difference of COD. In sheepskin, the difference of COD is between 1800 and 6100 mg / L.
