Detailed Description
Embodiments of the utility model: a noble metal mine drainage water recycling system comprises a high-density sedimentation tank 1, a sand filter tank 2, an ultrafiltration device 3, an RO reverse osmosis device 4, a nanofiltration device 5, an HPRO high-pressure reverse osmosis device 6, a forced circulation evaporator 7 and a forced circulation crystallizer 8 which are sequentially communicated.
The system also comprises a solar mechanical atomization evaporation pond 9, and a water inlet of the solar mechanical atomization evaporation pond 9 is communicated with a concentrated water outlet of the nanofiltration device 5.
The system also comprises a reuse water tank 10, wherein the fresh water outlet of the RO reverse osmosis device 4 is communicated with the water inlet of the reuse water tank 10, and the fresh water outlet of the HPRO high-pressure reverse osmosis device 4 is communicated with the water inlet of the reuse water tank 10.
The working principle of one embodiment of the utility model is as follows: the drain water is pumped to the high-density sedimentation tank 1 through the drainage pump of the underground central water pump room. Adding a flocculating agent PAC and a flocculating agent PAM into a mixing tank and a flocculating tank of a high-density sedimentation tank 1 respectively, mixing, performing flocculation reaction, reacting to generate larger alum flowers, then entering the sedimentation tank for solid-liquid separation, filtering the separated supernatant fluid in a sand filter tank 2, pre-desalting the filtered supernatant fluid in an ultrafiltration device 3, purifying water in an RO reverse osmosis device 4 (with a recovery rate of 70%), recycling the produced fresh water after the produced fresh water reaches the standard, and separating monovalent salt and divalent salt in a nanofiltration device 5 (with a recovery rate of 65%).
The concentrated nanofiltration water is sent into a solar mechanical atomization evaporation pond 9 for salt burning, and the main components of the mixed salt are calcium chloride and a small amount of calcium sulfate. Desalting the nanofiltration produced water by an HPRO high-pressure reverse osmosis device 6 (HPRO, recovery rate is 50%), and then delivering HPRO fresh water (Cl < - > is less than or equal to 300 mg/L) into a reuse water tank 10 for reuse; and (3) sequentially sending the HPRO concentrated water into a forced circulation evaporator 7 and a forced circulation crystallizer 8 to prepare the refined industrial salt industrial dry salt first-grade product which accords with GB/T5462-2015 industrial salt.
