[0002] Lanolin is a secreted oil attached to wool. It is a light yellow or brownish yellow ointment, sticky and greasy, with a weak and specific odor. It is easily soluble in chloroform or ether, soluble in hot ethanol, and very slightly soluble in ethanol. Its main components are esters of sterols, fatty alcohols and triterpenoid alcohols with approximately equal amounts of fatty acids, and a small amount of free fatty acids and hydrocarbons. There are two types of refined lanolin, namely anhydrous lanolin and hydrated lanolin. Anhydrous lanolin is a light yellow or brownish yellow ointment, sticky and greasy.

[0003] Heavy metals are present in the wool washing wastewater during the lanolin preparation process. Heavy metals are harmful to the human body. In order to prevent heavy metals from mixing into the finished anhydrous lanolin, the heavy metals in the wool washing wastewater need to be removed.

[0004] Currently, heavy metals in wool washing wastewater are filtered and removed by ultrafiltration membranes. Ultrafiltration devices are installed with the ultrafiltration membranes placed inside after opening the end caps, making the replacement of the ultrafiltration membranes inconvenient.
