摘要（英）：

The utility model relates to a treatment device for carrying out denitrification and defluorination on waste water by mixing hydrofluoric acid and nitric acid. The treatment device comprises a neutral reaction box (1), a preheater (7), a single-effect evaporator (9), a single-effect separator (10), a double-effect evaporator (12), a double-effect separator (15), a three-effect evaporator (16) and a three-effect separator (19), and is characterized in that the upper part of the neutral reaction box (1) is provided with a neutralization agent dry powder metering box (3), an agitator (4) and a pH meter (5), and is connected with a lift pump (6) by a pipeline; an outlet of the lift pump (6) is connected with an inlet of the preheater (7) by a pipeline; the double-effect evaporator (12) is provided with an agitator (13), the separator (15), a circulating pump (14) and a crystal mush discharge pump (27); and the evaporator (16) is provided with an agitator (17), the three-effect separator (19) and a circulating pump (18). The treatment device has the advantages of being compact in structure as well as simple and convenient in operation and maintenance, and realizing zero emission of the waste water.
