The LYF series of waste water deinking machines containing 2 patent tcchnologies. Upon the action of the know-how product of No.1 ink flocculating agent,this machine can,basec on the premise of keeping almost all fine fibers, remaining chemicals, heat energy and part of inorganic filler in the waste water, get rid of ink particles,tacky substance as well as part of inorganic filler in the water,which are detrimental to the process of pulping. It realizes the closde cycle of waste water in the process of deinking and pulping,and at the same time raise the rate of pulp output and reduce the loss of various kinds of chemicals and heat energy.And further owing to the recycling use of waste water,the heavy metal ions originally in the waste water are absorbed and carried away by the fiber,thus making it possible to soften the water quality.It can raise the degree of whiteness of pulp by about 2 degrees, but at the same time reduce the consumption of H2O2.FTV can also be used in waste water treatment in the non-deinking process in waste paper pulping.
