NOVELTY - Treating wastewater from papermaking comprises: (a) providing two or more strains selected from Halomonas and Bacillus species; (b) subjecting the strains to sterile culture; (c) mixing bacterial solutions to construct an artificial flora; (d) inoculating the constructed artificial flora into papermaking wastewater; and (e) subjecting papermaking wastewater of straw pulp to static treatment.    USE - The method is useful for treating wastewater form papermaking (claimed).    ADVANTAGE - The method provides a simple constructed flora, effective and efficient treatment method, and strong repeatability.    DETAILED DESCRIPTION - Treating wastewater from papermaking comprises: (a) providing two or more strains selected from Halomonas sp.Y2 CCTCC NO: M 208188, Halomonas sp.17-5 CCTCC NO: M 208192, Halomonas sp.19-A CCTCC NO: M 208186, Halomonas sp.19-D CCTCC NO: M 208193, Bacillus sp.Y4 CCTCC NO: M 208189, Bacillus sp.Y5 CCTCC NO: M 208190, Bacillus sp.17-1 CCTCC NO: M 208183, Bacillus sp.17-3 CCTCC NO: M 208184, Bacillus sp.17-4 CCTCC NO: M 208185, Bacillus sp.19-B CCTCC NO: M 208187, or Bacillus sp.Y6 CCTCC NO: M 208191; (b) subjecting the strains to sterile culture, until optical density (OD) 620 nm is reached to 10.0 or more; (c) mixing bacterial solutions based on a volume ratio of Halomonas sp.Y2:Bacillus sp.Y4:Bacillus sp.Y5:Bacillus sp.17-1:Bacillus sp.17-3:Bacillus sp.17-4:Halomonas sp.17-5:Halomonas sp.19-A:Bacillus sp.19-B:Halomonas sp.19-D:Bacillus sp.Y6 is 1-4:1-4:0-1:0-1:1-2:0-1:1-2:1-2:0-1:0-1:1-2, thus constructing an artificial flora; (d) inoculating the constructed artificial flora into papermaking wastewater in which pH is 9-11 and chemical oxygen demand (COD) is 1000-140000 mg/L, based on a volume ratio of 15-30%; and (e) subjecting papermaking wastewater of straw pulp to static treatment at 35-38 degrees C, where in the process of static treatment, stirring is implemented intermittently and samples are intermittently taken for determining pH, color, and COD index of papermaking wastewater; and when pH of the papermaking wastewater is reduced to 7.0-8.8, the treatment is ended.
