The invention discloses a device and a treatment method for deep purification treatment and reuse of mine water for production, and the device comprises a ground
water storage tank, a high-level primary
sedimentation water storage regulating tank, a reuse water tank and an underground production
water supply system, the ground
water storage tank is connected with the high-level primary
sedimentation water storage regulating tank through a
water pipe; the high-level primary
sedimentation water storage regulating tank is connected with a multi-medium filter through a purification device pipeline, the multi-medium filter is connected to the underground production
water supply system through a membrane
biological reaction tank and the reuse water tank, and an automatic dosing device is arranged on a
water delivery pipe. By additionally arranging the automatic dosing device and an
automatic control system, the dosing amount is adjusted according to the change of the water
inlet flow, the dosage of a medicament is accurately controlled, and the
flocculation effect is exerted to the maximum extent. And the MBR technology is utilized, so that the
solid-liquid separation efficiency is greatly improved. Purified mine water is disinfected in the mode that a generator is adopted to prepare
sodium hypochlorite on site, the operation cost is reduced, accurate
medicine adding is achieved, thedisinfection effect is improved, and the mine water returns to an underground production system again.
