The study of earthworm biological treatment on paper sludge

With the development of paper making industry, the environment concerns about paper sludge have increased.

The sludges can bedivided into several categories: The primary sludge coming from the productionof virginwood fiber; The de-inking paper sludge produced by removing inksfrom post-consumer fiber; The secondary sludge (activated sludge) from thesecondary treatment systems sludge; And the combined paper sludge which ismixed the primary sludge with the secondary sludge.
