Deinking methods, deinking agents, stickies issue created in the deinking process, the disposing of the deinking waste water and the solid rejects and the way to evaluate the deinking efficiency are reviewed in this paper.

Finally,how to improve the deinking efficiency by the shear factor is introduced.

We present a two-pass texture mapping procedure to produce Chinese-painting style image for 3D model.

It shows that the ferromagnetic toners (ferric oxide) in the pulp can be agglomerated with non-magnetic toners by agglomerator 1-octadecanol and used to carry on magnetic deinking and the deinking efficiency can reach 90.

The effects of molecular structures and properties of surfactants on MOW deinking efficiency were introducted in this paper.

The application such as evaluation of waste paper deinking efficiency, on-line mea s urement of kappa number during pulping, determinat.

The dissolved oxygen distribution and nitrogen removal effect in different structures of wetlands were investigated by two groups of comparison experiments(vertical flow with horizontal flow;single-stage with three-stage horizontal flow).

This paper studies material preparation,ion exchange model,acid wash and Fe exchange quantity effect for defluoridation material saturation absorbent quantity of model 732 changed property resin defluoridation;also concomitant ion influence on defluoridation effect of Fe(Ⅲ)-R and defluoridation mechanism of defluoridation material is explored.
