Papermaking sludge mainly contains high-molecular organic substances such as cellulose, hemicellulose and lignin, as well as fillers and coagulants, and does not contain heavy metals. It is a biomass resource
Papermaking sludge can be divided into 4 types: de-inking paper sludge, primary sludge, secondary sludge, and combined sludge. The sludge generated from the production of log fibers is called primary sludge; the sludge generated by deinking the recycled waste paper is called deinking papermaking sludge; the secondary sludge is also called activated sludge, From the secondary treatment process of sewage, the secondary treatment generally uses biochemical methods to remove colloidal and dissolved organic pollutants; the sludge mixed with primary sludge and activated sludge is called mixed sludge.
