Processing process and processing system of high-concentration organic wastewater with rubber chemicals

Abstract

The invention discloses a processing process and a processing system of high-concentration organic wastewater with rubber chemicals. The processing process comprises steps of removing salt in the wastewater and regulating pH; performing activated carbon catalyst catalysis oxidation reaction on the wastewater and regulating pH; removing suspended matters in the wastewater; removing COD and salinityin the wastewater; removing COD and organic matters in the wastewater; and deeply oxidizing the wastewater and adding H2O2 and then discharging. The processing process can treat high-concentration organic wastewater with rubber chemicals and discharge the wastewater reaching the standard. The processing system has the advantages of being low in cost, occupying a small area, simple operation conditions, and being suitable for large-scale treatment.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a treatment process and system for high-concentration organic wastewater of rubber additives. Background technique [0002] Rubber additives are additives for rubber processing, including vulcanizing agents, vulcanization accelerators, etc. The wastewater of rubber additives mainly comes from the washing process and filtering mother liquor. The COD (Chemical Oxygen Demand, chemical oxygen demand) in the wastewater is very high. The wastewater not only contains various accelerators but also aniline, toluene, and cyclohexylamine in the production process. , tert-butylamine and other by-products, which also contain a relatively high concentration of sodium salt, which belongs to high-concentration refractory organic saline wastewater. Due to the high content of organic pollutants in the wastewater, and the strong toxicity of sodium chloride and accelerators to microorg...

AI Technical Summary

Problems solved by technology

Due to the high content of organic pollutants in the wastewater, and the strong toxicity of sodium chloride and accelerators to microorganisms, the biochemical treatment is very difficult, so the treatment of this type of wastewater is mostly based on physical and chemical treatment processes such as distillation and wet oxidation. Mainly, these treatment processes have high investment and operating costs, large floor space, and harsh operating conditions, which are not conducive to large-scale implementation
