METHOD FOR CONTROLLING CHLORINATED NITROGEN-CONTAINING DISINFECTION BY-PRODUCT IN WATER

摘要

Disclosed is a method for controlling a chlorinated nitrogen-containing disinfection by-product in water, including the following steps: firstly, the pH value of a water sample is controlled, ultraviolet irradiation treatment is used and a persulfate or hydrogen persulfate is added at the same time, then chlorination disinfection is carried out, and finally, aeration treatment is carried out, so that a water sample from which the chlorinated nitrogen-containing disinfection by-product in water is removed is obtained. The method can effectively control the formation of chlorinated N-DBPs, and can effectively reduce the amount of trichloromethane in the subsequent chlorination disinfection process.
