The invention discloses a method for treating waste liquid of dipping of cord fabric, which comprises the following steps: S1, grid filtration; S2, coagulation reaction; S3, plate and frame pressure filtration; and S4, advanced treatment. The advantages of the invention are: special agent for dipping wastewater treatment: the agent has both the coagulation and sedimentation effect of inorganic flocculants, and the high-efficiency net capture and sweeping effects of polymer flocculants. , rolling sweeping, flocculation and other physical and chemical effects, oxidative degradation of pollutants in sewage, high-pressure diaphragm pressure filtration: the sludge can be disposed of harmlessly, and the moisture content of the sludge is as low as 60%; in the coagulation reaction tank , respectively, through chemical reaction, chemical oxidation, advanced oxidation, coagulation reaction and other processes to treat the filter press effluent to meet the requirements of environmental protection treatment and discharge standards. |
