The present invention discloses a biochemical
neutralization treatment method and integrated device for high-acidity HMX production
wastewater, which belongs to the field of production
wastewater treatment in the explosives industry. The present invention includes a
reflux aeration tank, a contact
mixing tank, a biochemical
neutralization tank, a
sedimentation tank, an
automatic control cabinet, a
reflux pump, an
aeration fan, a water distribution plate, a guide plate, a
pH probe, an
aeration zone, an aerator, a DO probe, a filler zone, a transverse guide plate and a water inlet pump; a partition is used to set up four units of a
reflux aeration tank, a contact
mixing tank, a biochemical
neutralization tank and a
sedimentation tank in series; an aerator is provided at the bottom of the reflux aeration tank, and the biochemical neutralization tank is divided into a filler zone and an aeration zone. A biological filler is provided in the middle of the filler zone, and an aerator is provided at the bottom of the aeration zone; a vertical guide plate is provided on the water inlet side of the
sedimentation tank, and a horizontal downward water distribution plate is provided at the bottom of the guide plate; the device enables the
wastewater treatment facility to operate stably while reducing the maintenance cost of
process equipment, significantly reducing the treatment pressure of the subsequent
sewage treatment process.
