Example Embodiment
[0029] Example one
[0030] A certain ammunition destruction station concentrates on destroying used ammunition. The annual intensive work time is about two weeks, producing 20m of waste water from ammunition dismantling. 3 , It flows into the collecting basin, the size of the existing collecting basin is 3.3m×3.3m×3m, which can meet the requirements.
[0031] The sump is located underground and is covered with prefabricated cement slabs. An auxiliary room is built above the sump to protect the processing equipment and eliminate the noise caused by the air compressor.
[0032] The waste water is pumped into the air flotation filter, and most of the flocs in the waste water are removed under the air flotation action of the air flotation filter, and SS (Suspended Solid) is reduced from 600mg / l of raw water to 100mg / l; The air flotation device has no degradation effect on COD (chemical oxygen demand), but due to the reduction of suspended organic matter, the COD of the raw water is r...
Example Embodiment
[0042] Example two
[0043] It is basically the same as the first embodiment, but the difference lies in:
[0044] Activated carbon filter material, particle size d min 2mm, the thickness of the filter layer is 0.5m.
Example Embodiment
[0045] Example three
[0046] It is basically the same as the first embodiment, but the difference lies in:
[0047] Activated carbon filter material, particle size d min It is 4mm, and the thickness of the filter layer is 1.5m.
