| titleOfInvention | Method for reducing COD (Chemical Oxygen Demand) of tebuconazole industrial wastewater |
| abstract | The invention discloses a method for reducing COD (Chemical Oxygen Demand) of tebuconazole industrial wastewater. The method comprises the steps: adding an acid solution in the tebuconazole industrial wastewater to adjust to be acidic; after stirring at a room temperature, filtering to remove acid non-soluble substances, collecting filtrate; adding a divalent iron salt and hydrogen peroxide in the filtrate, performing a Fenton reaction, and at the end of the reaction, adding an alkaline solution to adjust to be alkali, thus obtaining a mixed solution; and adding an oxidizing agent in the mixed solution, reacting at a temperature of 20-50 DEG C for 2-6h, standing and filtering to obtain the degraded wastewater, wherein the oxidizing agent is sodium chlorate, sodium hypochlorite or calcium hypochlorite, with a concentration of 0.1-1M. The invention provides a treating process of adjusting acid for precipitation, acidic Fenton oxidation and alkali ferrate oxidation and the treating process can be used for removing organic matters with different properties out of wastewater in combination with processes of flocculation, acidic oxidation and alkali oxidation; therefore, the purpose of deeply oxidizing the tebuconazole industrial wastewater is realized, and the adopted oxidizing agent is safe and environment-friendly, and is high in treating efficiency, and free from producing secondary pollution. |
