| titleOfInvention | Method for controlling generation of nitrogenous disinfection byproducts in raw water body by pre-oxidation of bicarbonate/hydrogen peroxide |
| abstract | The invention provides a method for controlling generation of nitrogenous disinfection byproducts in an original water body by pre-oxidizing bicarbonate/hydrogen peroxide, which comprises the following steps: adjusting the pH value of the original water body containing the soluble organic nitrogen to 7-10 by using alkali, then adding bicarbonate and an oxidant, adding a disinfectant to react for 24-48 h in a light-tight environment according to the content of the soluble organic carbon and the residual amount of hydrogen peroxide in the original water body. The bicarbonate and the hydrogen peroxide are environment-friendly reagents, and the generated peroxymonocarbonate radical has strong oxidizing property and no reaction selectivity, and can degrade all organic matters; the invention provides a method for removing the precursor of the disinfection by-product by a Fenton-like preoxidation system from the aspect of source control, and the nitrogen-containing disinfection by-products such as halogenated nitromethane, halogenated acetamide and the like in the water delivered by a water plant can be effectively controlled, so that the safety of drinking water is improved. |
