[0002] In the production process of electronic-grade polysilicon, especially in the post-processing pickling stage, a large amount of acidic waste gas and waste liquid will be generated. The existing treatment processes all use large-scale gas-liquid treatment equipment, and use three-stage leaching towers to oxidize, alkali wash, and water wash harmful gases and liquids respectively, so as to meet the emission standards. However, during the maintenance of the production equipment or when adjusting the local process, some of the waste gas and waste liquid generated cannot be discharged to the gas-liquid treatment system in a centralized manner. Multiple modifications are required to ensure the normal discharge of waste gas and waste liquid, and the gas-liquid treatment device is in a low-load operation state for a long time, resulting in increased production costs. At the same time, because the amount of acid gas is too small at this time, the gas-liquid phase cannot guarantee the contact area during the absorption process, and the gas-liquid treatment effect is greatly reduced.
