Specification：

Rubber vulcanization accelerator DPG wastewater treatment method. First, the wastewater is subjected to acid-base flocculation, and the filtered wastewater enters an electrolytic cell equipped with a micro-electrolytic filler at 60-80 ° C, micro-electrolysis for 2 to 5 hours, after micro-electrolysis The wastewater is filtered, and the filtered wastewater is added with 10% to 30 ml of hydrogen peroxide/L wastewater to a concentration of 30% hydrogen peroxide, adjusted to pH=2 to 4, treated for 2 to 5 hours, and then added to flocculation at a ratio of 200 to 500 mg/L of wastewater. The agent PAC is flocculated, the pH is adjusted to 8 to 10, and the sedimentation time is 1 to 2 hours. After sedimentation, it is filtered first, and the filtered wastewater is adsorbed by activated carbon and resin, and the removal rate of CODcr reaches over 98%, reaching the discharge standard. The method has simple process, low equipment investment, low energy consumption, high COD removal rate, can reach more than 98%, better treatment effect, meet emission standards, and is easy to industrialize.

Promoter DPG is a medium speed accelerator for rubber, a medium speed accelerator for natural rubber and synthetic rubber, and an activator for thiazoles, thiurams and sulfenamide accelerators. The obtained product has good aging resistance. It is mainly used to manufacture rubber products such as tires, rubber sheets and soles. During the production process of the accelerator DPG, a large amount of high-concentration salt-containing organic wastewater is produced, which is difficult to handle, and its production and development are greatly restricted due to environmental pressure. The wastewater in the DPG production process mainly comes from the mother liquor distillation and water washing process. The salt and COD concentrations are high, with color and odor, and the water contains a variety of heterocyclic organic compounds, which are difficult to treat by biochemical methods. At present, there are few reports on the treatment of this type of wastewater, mostly evaporative distillation and other processes, which have large energy consumption and poor treatment effect.

A rubber vulcanization accelerator DPG wastewater treatment method: firstly, the wastewater is subjected to acid-base flocculation, and the filtered wastewater enters an electrolytic cell equipped with a micro-electrolytic filler for electrolysis and filtration, and the filtered wastewater is further added with hydrogen peroxide for Fenton oxidation, after oxidation. The wastewater is flocculated, sedimented and filtered. The filtered wastewater is adsorbed by activated carbon and resin, and the removal rate of CODcr reaches over 98%, reaching the discharge standard.

A rubber vulcanization accelerator DPG wastewater treatment method, the wastewater is subjected to acid-base flocculation, and the filtered wastewater enters an electrolytic cell equipped with a micro-electrolytic filler at 60-80 ° C, micro-electrolysis for 2 to 5 hours, and the wastewater after micro-electrolysis is carried out. Filtration, adding 10 to 30 ml of hydrogen peroxide per liter of filtered wastewater, adding hydrogen peroxide with a concentration of 30% hydrogen peroxide, adjusting pH=2 to 4, treating for 2 to 5 hours, and then adding flocculant PAC at a ratio of 200 to 500 mg/L of wastewater. Flocculation, pH adjustment 8~10, settling time is 1-2 hours; filtered after sedimentation, the filtered wastewater is adsorbed by activated carbon and resin, and the removal rate of CODcr is over 98%.
