[0003] However, the above-mentioned manganese mine gushing water treatment system is by adding lime or sodium hydroxide, using manganese ions to form a hydroxide with a small solubility product under alkaline conditions, and removing the large particles precipitated by aggregation. However, the removal of manganese ions by single neutralization precipitation requires adjusting the pH value to a high range, which results in a large amount of alkali and a large amount of acid added to the effluent to adjust the pH. The addition of excess alkali will cause the co-precipitation of calcium and magnesium ions coexisting in the manganese mine gushing water, resulting in low manganese content and high calcium and magnesium content in the precipitate, reducing the grade of manganese, and the generated manganese-containing sludge cannot be directly utilized in industry, so the enterprise will transport the manganese-containing sludge to the manganese slag landfill site for landfill or entrust a third-party enterprise for disposal. This not only causes a large amount of manganese resources to be wasted, but also significantly increases the cost of sludge treatment for the enterprise.

[0057] Specifically, the filler arranged in the adsorption column 10 is an amine oxime-based nanofiber or a carboxyl nanofiber. The amine oxime-based nanofiber is used for high-hardness manganese mine water (high concentration of Ca ions and Mg ions), and the carboxyl nanofiber is used for low-hardness manganese mine water (low concentration of Ca ions and Mg ions), which can efficiently adsorb and remove manganese ions in the wastewater.

[0060] In one embodiment, further comprising a backwashing structure, the backwashing structure comprises a backwashing pipe and a second booster pump, the water inlet end of the backwashing pipe is arranged at the bottom of the clean water tank 9, the second booster pump is connected with the backwashing pipe, a first water stop valve is arranged on the clean water pipe, the water outlet end of the backwashing pipe is connected on the clean water pipe between the first water stop valve and the adsorption column 10, the water outlet end of the backwashing pipe is further connected with a second water stop valve, and a liquid discharge valve is arranged on the adsorption column 10.

[0061] In use, the backwash liquid is filled into the water tank 9, the first water stop valve is closed, the second booster pump and the second water stop valve are opened, the backwash liquid flows into the adsorption column 10 from the backwash pipe through the second booster pump, the desorption of the adsorption column 10 in the backwash liquid adopts 3%-5% hydrochloric acid or sulfuric acid solution, and the regeneration adopts ammonia water (4:1) solution, the desorption liquid is treated through the sediment recovery unit, and the effluent returns to the adjusting tank 1 for treatment.

[0063] The working principle of the utility model is as follows: the manganese mine gushing water to be treated is pumped from the adjusting tank 1 into the carbonization reaction tank 3, the carbonization agent adding tank 14 adds carbonization agent into the carbonization reaction tank 3, and the carbonization agent reacts with the manganese mine gushing water. Subsequently, the solution is sequentially pumped into the mixed reaction tank 4 and the flocculation reaction tank 5, the manganese-containing sludge and the reaction solution are precipitated after the coagulation reaction and the flocculation reaction, the manganese-containing sludge is transferred into the sludge tank 6, the reaction solution is introduced into the inclined plate sedimentation tank 7 for preliminary solid-liquid separation, the separated sludge is transferred into the sludge tank 6 for storage, and the clear solution in the upper layer is transferred into the intermediate tank 8. The sludge and the residual solution in the sludge tank 6 are transferred to the sludge conditioning tank 2 through the first pump and the first sludge pipe, PAM is added into the sludge conditioning tank 2 for further flocculation reaction, and then transferred to the stacked screw pressure filter 11 for compression. The solution is discharged into the filtrate collecting tank 12 and then transferred to the adjusting tank 1 for the next round of treatment. The concentrated sludge is discharged from the second sludge outlet and then transported out for use. The clear solution in the upper layer is transferred into the adsorption column 10 to remove the residual manganese ions and then discharged into the water tank 9. The solution in the water tank 9 can meet the discharge standard and be directly discharged.

[0064] In the process of carbonization reaction using the embodiment, the carbonization agent is used to make the pH of the solution 8-9, so that the manganese ions can be in a state of reaction advantage under the condition of coexistence of calcium and magnesium, the precipitation of calcium and magnesium ions is effectively reduced, the manganese in the manganese mine gushing water is accurately settled, and a large amount of calcium and magnesium ions is not precipitated, so that high-grade manganese-containing sludge is obtained. Secondly, the carbonization reaction for manganese ion precipitation does not need to depend on a high pH environment, and the pH environment is always less than 9, so that the pH needs not to be adjusted in the subsequent process.

[0065] On the other hand, the carbonization and adsorption in the embodiment have relevance. After the three reaction pools, the adsorption column is used for adsorption treatment, no other exogenous substances are introduced, and the wastewater can be deeply purified, so that the manganese-removed water body meeting the standard is obtained. The existing manganese mine gushing water treatment system uses sodium hydroxide for early manganese removal, and if adsorption treatment is used for deep manganese removal, the adsorption cannot adjust the pH of the water body, and the acid needs to be added for adjustment in the later period, and the pH required for manganese removal by sodium hydroxide is greater than 9, which will also increase the precipitation rate of calcium and magnesium to a certain extent.

[0066] If the carbonization agent is added for early manganese removal in the embodiment, and other methods are used for deep manganese removal, generally, exogenous substances need to be introduced, but the increase of exogenous substances will increase the treatment difficulty and reduce the content of manganese in the precipitation; and some exogenous substances have special requirements for pH when used for deep manganese removal, and the pH may not be compatible with the pH in the embodiment.

[0067] Therefore, the manganese mine gushing water treatment system provided in the embodiment combines the carbonization reaction pool and the adsorption column, so that the content of manganese in the sludge reaches more than 30%, and even more than 35%, which can be directly used as an electrolytic manganese production raw material and can be directly resource utilization. After the wastewater is treated by adsorption in the embodiment, the effluent Mn is less than 2 mg / L, which meets the first emission standard of GB8978-1996 "Integrated Wastewater Discharge Standard", and the effluent pH does not need to be adjusted; the process flow is simple, easy to realize industrialization, and the manganese resources in the wastewater are effectively utilized, the cost is lower than that of the traditional process, and has a high application prospect.

[0068] The above is only the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process conversion obtained by using the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
