| titleOfInvention | Pretreatment method of high-concentration organic wastewater in production process of mercapto heterocyclic compounds |
| abstract | The invention discloses a pretreatment method of high-concentration organic wastewater in the production process of mercapto-heterocyclic compounds, which comprises the steps of sequentially removing residual mercapto-heterocyclic compounds in the organic wastewater from wastewater with complex components and high organic matter concentration in the production process of the mercapto-heterocyclic compounds by a copper salt precipitation method, removing ammonia nitrogen in the organic wastewater by an air stripping method, removing thiocyanate radicals in the organic wastewater by a cuprous salt reduction liquid phase precipitation method, and oxidatively degrading residual organic matters in the organic wastewater by a Fenton reaction. The method realizes the great reduction of COD and NH in the wastewater 3 -N and SCN ‑ The content of the compound is high, the difficult problems that the COD concentration in the production wastewater produced in the synthetic process of the mercaptothiazole and the mercaptotriazole is high, the harmful components are more and the treatment is difficult are solved, and a foundation is provided for the subsequent biochemical treatment process. |
