Abstract
The invention discloses a viscose fiber waste water treatment method. The viscose fiber waste water treatment method comprises air floatation and deposition, and muddy water separation. The viscose fiber waste water treatment method is characterized in that alkaline waste water comprising exhaust gas recovery waste water, stock solution and spinning head lifting waste water is collected and fed into an alkaline waste water tank; acidic waste water comprising acid station outlet water is collected and fed into an acidic waste water tank; zinc-containing waste water comprising spun fluff molding tank outlet water, acid removal water and two-bath process overflow is collected and fed into a zinc-containing waste water tank; the alkaline waste water and the zinc-containing waste water are fed into a mixing air-floatation tank for mixing, wherein in mixing air-floatation, a pH is adjusted to a value of 3.0 to 4.0; the water output by the mixing air-floatation tank and the acidic waste water are fed into a physicochemical treatment tank and a biochemical treatment tank to be subjected to precipitation and muddy water separation; and when the treated water reaches the standard, the treated water is discharged. The viscose fiber waste water treatment method solves the problem of difficult viscose fiber waste water. The viscose fiber waste water treatment method has the characteristics of simple processes and good effects.
Description
Technical field
The present invention relates to a kind of viscose fiber method of wastewater treatment.
Technical background
Viscose fiber waste water is subjected to the influence of viscose glue production technique, and reluctant factor mainly is Mierocrystalline cellulose residue, heavy metal zinc ion, sulfonium ion etc., usually causes the not good or system's fluctuation of service of wastewater treatment efficiency, and draining can not be up to standard.
In the viscose glue production technique, no matter produce nonwoven, high-strength, still common silk, the Mierocrystalline cellulose residue mainly results from the stoste processing procedure; Zine ion is mainly spinning experienced fine hair forming tank water outlet, disacidify wash water and two bath overflows from acid bath; Sulfonium ion mainly from adding of dithiocarbonic anhydride use with the waste gas recovery in acid, alkali cleaning.
Summary of the invention
Its purpose of the present invention just is to provide a kind of viscose fiber method of wastewater treatment, has solved the reluctant problem of viscose fiber waste water.Has simple, the good effectiveness of technology.
The technical scheme that realizes above-mentioned purpose and take comprises:
Air supporting and deposition, mud-water separation,
(1) alkaline waste water comprises waste gas recovery, stoste, spins the alkaline waste water that practice to rise a waste water and be collected into the alkaline waste water pond;
(2) acid waste water comprises that the acid waste water of acid station draining is collected into the acid waste water pond;
(3) zinc-containing water comprises that spinning experienced fine hair forming tank water outlet, disacidify wash water and two zinc-containing waters of bathing overflow is collected into the zinc-containing water pond;
(4) said alkaline waste water and zinc-containing water entering mixing air flotation pool mixes, and PH is controlled at 3.0 ~ 4.0 mixes air supporting;
(5) said mixing air flotation pool output and said acid waste water get into materialization, biochemical treatment tank;
(6) deposition, mud-water separation;
(7) qualified discharge.
Compared with prior art, beneficial effect of the present invention is, has adopted three strands of waste water to get into the sewage disposal method of combination treatment again, thereby has solved the reluctant problem of viscose fiber waste water.Has simple, the good effectiveness of technology.
