Technology for treating waste water produced by rubber accelerator production

The invention relates to a technology for treating waste water produced by rubber accelerator production. The technology comprises the following steps of 1, adjusting quality and an amount of waste water produced by rubber accelerator production, adjusting pH value of the waste water to 11-13, adjusting a temperature of the waste water to 60-90 DEG C, and carrying out stirring for 2-4h for alkaline hydrolysis, 2, adjusting a pH value of the waste water to 5.0-6.0 by sulfuric acid, and carrying out evaporation desalination, 3, carrying out anaerobic treatment on the waste water subjected to evaporation desalination, 4, orderly carrying out anaerobic treatment, aerobic treatment and secondary precipitation of the anaerobic precipitation product water, wherein a mixed solution and sludge backflow process is carried out between the secondary precipitation and the anaerobic treatment, and 5, orderly carrying out Fenton catalytic oxidation, coagulating sedimentation and filtration deep treatment on the secondary precipitation product water. According to the characteristic of quality and amount of waste water produced by rubber accelerator production, the technology combines a physicochemical treatment method and a biochemical treatment method, realizes that COD and ammonia nitrogen indexes of waste water stably reach corresponding emission standards, has a compact process, is convenient for operation, has low energy consumption and strong practicality, and can be industrialized easily. The waste water treated deeply can be used as recycled water so that waste water recycle is realized.
