Abstract:Trihalides and haloacetic acids are representative disinfection by -products (DBPs)in Water
Supply the amounts of disinfection by -products are too high in waterworks,it will affect the
water security in and THMs and HAAs from two different treatments,the
DBPs concentration changes were anglysed,the two sets of process water treatment effect pared.
The results showed that the increase of disinfection by-products of water treated by the process of folding
