| titleOfInvention | Method for treatment of petrochemical spent caustic wastewater |
| abstract | The present disclosure relates to wastewater treatment, and more particularly to a method for treatment of petrochemical spent caustic wastewater. The method includes the following steps: a) adjusting the pH of petrochemical spent caustic wastewater to 7 to 12, standing, removing the organic layer, and obtaining the pretreated wastewater; b) activating a plasma reactor loaded with resin photocatalyst, passing the pretreated wastewater into the plasma reactor for treatment in the presence of oxygen, and obtaining the treated wastewater. The method provided by the present disclosure can effectively improve the COD removal rate of petrochemical spent wastewater, and the whole treatment process is carried out under normal temperature and normal pressure, with a simple process and the ability to realize continuous operation. The experimental results show that the COD removal rate of petrochemical spent caustic wastewater using the method provided by the present disclosure is above 98%. |
