(1) in waste water, acid adding is neutralized to its pH is 7.2；
(2) waste water in step (1) adds defoamer, then through aeration defoaming treatment 6 hours, described defoamer accounted for useless
The 5% of water water body weight；
(3) adding microbial water-purifying agent in the waste water in step (2), its addition accounts for the 0.3% of waste water gross weight；
Described microbial water-purifying agent parts by weight are: nitrobacteria mycopowder 2.0, Paracoccus denitrificans mycopowder 1.5, sulfur bacteria mycopowder
0.8, microphenomenon of degradation of aniline mycopowder 1.2, flocculated bacteria mycopowder 1.5, silicate bacteria mycopowder 1.0 and bacillus subtilis mycopowder 1.2；
(4) waste water in step (3) adds enzyme preparation；The parts by weight of described enzyme preparation are: pectase 1.5, fiber
Element enzyme 0.8, oxidoreductase 0.8, xylanase 0.6, alkaline protease 0.6 and monoamine oxidase, MAO 0.9, its addition accounts for waste water
The 0.35% of gross weight；
(5), during the water body in step (4) sends into Sedimentation tank, filter.
8. rubber accelerator NOBS production wastewater treatment technique as claimed in claim 1, it is characterised in that described defoamer
For any one in polyethers, higher alcohols, organosilicon.
