Purification method for wastewater of ammunition disassembly

The invention discloses a purification method of ammunition resolving wastewater, which includes the purification steps that: firstly, oil slick and suspended particulates are filtered and removed; secondly, under the irradiation of ultraviolet light, ozone is mixed and reacted with wastewater by the micro bubble form; thirdly, reacted water flows into a biological pool, the biological pool purifies the wastewater and indicates the water quality, and the wastewater reaches the mark and can be discharged outside when in the normal state. Through the reinforced pretreatment, the purification method removes suspended substance and granule precipitate in the wastewater are filtered and removed before the ozone oxidation treatment, the consumption of the suspended substance and the granule precipitate to the ozone during the oxidation is reduced, and the purification method of the ammunition resolving wastewater, which has short detention time, high treatment efficiency, and good yielding water quality, is invented successfully by combining the ozone oxidation and the traditional biological pool technology.
