[0002] The wastewater generated in the beneficiation production process is one of the main factors of mine environmental pollution. The pollutants contained therein mainly include solid suspended matter, persistent heavy metal ions, flotation reagents and oil stains, etc. If these wastewaters are directly discharged without treatment, they will have destructive effects on rivers, soil, farmland, wetlands, etc. in the surrounding and downstream areas of the plant, and ultimately endanger human health. Therefore, it is very important to take measures to discharge or re-input the treated beneficiation wastewater into production.

[0003] Multiple work links in the beneficiation production process will generate wastewater. Usually, the generated wastewater is collected in one place for treatment, which reduces the land occupation of wastewater treatment facilities and facilitates the overall planning of the treated water. In actual production, a sedimentation tank is set to collect the wastewater generated in each work stage, and a reagent beneficial to the sedimentation of suspended matter is mixed in to reduce the suspended matter in the wastewater entering the subsequent treatment stage.

[0004] However, there are differences in treatment measures and space among the various work links of beneficiation production, which makes the pipeline at the input end of the sedimentation tank more complex, and the water pressure and flow of the wastewater input into the sedimentation tank are unstable. When the water pressure and flow are large, the impact on the water body in the buffer tank is large, and the settled suspended matter is easy to be stirred up with the water body and enter the downstream wastewater treatment system.

In this process, the water pressure and water flow of the wastewater output by each water collecting pipe 3 are unstable, the buffer pool 11 can mix the wastewater output by each water collecting pipe 3 and offset most of the impact force, so that the water flow rate of the water body entering the buffer pool 11 through the water-permeable holes 21 is relatively stable, and the agglomerates at the bottom of the settling pool 12 are prevented from being stirred up due to the unstable water flow rate.

[0038] Optionally, the input end of the drain pipe 5 and the input end of the sludge discharge pipe 6 are arranged inside the side of the settling pool 12 away from the buffer pool 11, because the water body in the pool body 1 flows from the buffer pool 11 to the settling pool 12, so that the water body on the side of the settling pool 12 away from the buffer pool 11 is relatively stable, and the settling material in the waste water also gathers there.

[0050] According to the amount of wastewater input into the buffer pool 11 in a unit time period before the detection moment and the ratio relationship between the amount of wastewater and the amount of reagent, the amount of reagent required to be injected into the buffer pool 11 at the detection moment is determined as a target amount of reagent;

[0051] The on-off of the reagent supply pipe 4 is controlled to inject the reagent into the buffer pool 11, and the on-off amount of the reagent supply pipe 4 is controlled to change, so that the amount of reagent input into the buffer pool 11 in a unit time period after the detection moment is consistent with the required amount of reagent;

[0052] When the liquid level of the settling pool 12 is higher than a first preset liquid level, the drain pipe 5 is controlled to be on, otherwise, the drain pipe 5 is controlled to be off; when the liquid level of the settling pool 12 is higher than a third preset liquid level, the on-off amount of the drain pipe 5 is controlled to increase, and the on-off amount of each collecting pipe 3 is controlled to decrease;

[0054] It should be noted that the time interval between each two adjacent detection moments is consistent, and the time interval between each two adjacent detection moments is a unit time period.

[0055] It is to be noted that the turbidity refers to the degree of hindering of light passing through the solution, which includes the scattering of light by suspended matters and the absorption of light by solute molecules, and is expressed in units of NTU.
