Embodiment 1
[0023] A combined water treatment method for the simultaneous removal of sulfate, hardness and total dissolved solids, comprising the following steps:
[0024] (1) Use special magnetic resin to remove sulfate in water, and obtain primary purified water through solid-liquid separation; among them, special magnetic resin is magnetic anion exchange resin, and its exchange group is bicarbonate; special magnetic resin removes sulfate in water The sulfate treatment process adopts the direction of upward flow; at the same time, synchronously extract the invalid resin and add the regenerated resin to keep the total capacity of the resin in the system relatively stable; the regeneration method of the special magnetic resin is: use sodium bicarbonate with a concentration of 5% Solution treatment for 45min;
[0025] (2) Add hardness-removing medicament to coagulate in the first-level purified water, contact and filter to remove sediment to obtain secondary purified water; wherein, the ha...
Embodiment 2
[0034] A combined water treatment method for the simultaneous removal of sulfate, hardness and total dissolved solids, comprising the following steps:
[0035] (1) Use special magnetic resin to remove sulfate in water, and obtain primary purified water through solid-liquid separation; among them, special magnetic resin is magnetic anion exchange resin, and its exchange group is bicarbonate; special magnetic resin removes sulfate in water The sulfuric acid treatment process adopts the upward flow direction; at the same time, the invalid resin is extracted synchronously and the regenerated resin is added to keep the total capacity of the resin in the system relatively stable; the regeneration method of the special magnetic resin is: use sodium bicarbonate with a concentration of 8% Solution treatment for 30min;
[0036] (2) Add hardness-removing medicament to coagulate in the first-level purified water, contact and filter to remove sediment to obtain secondary purified water; wh...
Embodiment 3
[0045] A combined water treatment method for the simultaneous removal of sulfate, hardness and total dissolved solids, comprising the following steps:
[0046] (1) Use special magnetic resin to remove sulfate in water, and obtain primary purified water through solid-liquid separation; among them, special magnetic resin is magnetic anion exchange resin, and its exchange group is bicarbonate; special magnetic resin removes sulfate in water The sulfate treatment process adopts the upward flow direction; at the same time, the invalid resin is extracted synchronously and the regenerated resin is added to keep the total capacity of the resin in the system relatively stable; the regeneration method of the special magnetic resin is: use sodium bicarbonate with a concentration of 10% Solution treatment for 15 minutes;
[0047] (2) Add hardness-removing medicament to coagulate in the first-level purified water, contact and filter to remove sediment to obtain secondary purified water; wh...
