A kind of control method of pre-chlorine dioxide by-product chlorite |
| abstract |
The invention relates to the field of water treatment, and relates to a method for controlling pre-chlorine dioxide by-product chlorite. The method comprises: (1) pre-oxidizing the raw water with chlorine dioxide; (2) treating the raw water in an activated carbon filter or a carbon sand filter after the treatment in step (1), and the hydraulic retention time is generally 12-15 minutes. Through a large number of experiments, the present invention preferably adopts granular columnar activated carbon that is most suitable for removing ClO 2 , and combines with specific dosage, pH, temperature and other conditions to form a dynamic adsorption and removing ClO 2 scheme , so as to achieve an overall reduction of disinfection effects The purpose of the product is to control the pre-chlorite by-product chlorine dioxide. |
