Abstract

The invention discloses a waste water recycling pad dyeing long machine and a waste water recycling method thereof. The waste water recycling pad dyeing long machine comprises a desizing, scouring and bleaching combined machine, a mercerizer, a first recovery processing box, a second recovery processing box, a third recovery processing box, a first recovery pump, a second recovery pump, a third recovery pump, a light alkali recovery pool, a dilatation evaporator, an alkali dosing pool, a recovery pool, a recovery pump and connecting pipelines. The method comprises the following steps: a. introducing washing waste water into the first recovery processing box and then pumping into a scouring machine after filtering; b. introducing light alkali with high alkali concentration into the dilatation evaporator for processing through the recovery pool, then introducing processed high-concentration alkali liquor into the mercerizer for reuse and introducing processed water into an oxygen bleaching washing box for use; and c. introducing oxygen bleaching process water into the second recovery processing box and then introducing into a desizing machine washing box for use after filtering. The invention has the advantages of small waste water discharge, high efficiency, energy conservation, etc., saves a large amount of production water and alkali, and meets requirements of energy saving and emission reduction.

Description
