Abstract: Earthworm has been proved to be effective in processing organic solid waste such as straw, livestock manure and municipal sludge. It is necessary to separate the live earthworm and worm-cast from resulting vermicomposting because this is the most labor，low efficiency and time intensive stage. This paper discussed the problems in the procession of separating earthworm, reviewed different separating engineering technology and devices, and analyzed the future trend of research, which was expected to provide references for upgrading separating technology and designing of separator.
