If the purification degree of the raw materials in the tank body 1 reaches the expected degree, the purifier can maintain the current working state; if the purification degree of the raw material in the tank 1 does not reach the expected level, the purification effect of the purifier can be improved by reducing the flow rate of the feed passage 2, increasing the medicine addition amount of the feed passage 2, and the like.

The purifier provided by the application can integrate the procedures of flocculation, separation, precipitation and sludge collection of raw materials such as mine water burst, mineral separation wastewater and the like in the purification process into one tank body 1, and has the advantages of small occupied area, high treatment efficiency and the like.

Wherein, the upper parts of the first-stage sedimentation zone 41 and the second-stage sedimentation zone 42 are reserved with enough space, and the space can be filled with filler according to specific process requirements to form a filter layer, thereby improving the purification efficiency.

Furthermore, in some embodiments, the top of the tank 1 may be provided with a service portion, a vent, and a drain; a drain 12 and a sludge collecting area access 13 can be arranged at the bottom of the tank body 1, and sludge and other sediments can be discharged out of the tank body 1 from the drain 12.

Taking the purification operation of beneficiation wastewater as an example, the wastewater which is subjected to heavy metal capturing and PH adjustment can enter the purifier provided by the application from the flocculation mixing area corresponding to the feeding channel 2, and in the process, the medicament can be added into the feeding channel 2, so that the medicament is fully mixed with the wastewater in the feeding channel 2, and the flocculation of impurities in the wastewater by the medicament is realized. The mixture of waste water and medicament enters the central separation area corresponding to the first separation channel 3 from the feeding channel 2, contacts the pipe wall of the first separation channel 3 and spirals downwards along the pipe wall to separate and settle the flocs in the mixture. A water deflector 6 is arranged below the first separation channel 3 to prevent the aforesaid mixture from directly striking down the flocs which have settled and accumulated. Of course, in the above process, larger flocs are already deposited at the bottom of the tank 1, and the liquid level in the tank 1 is also continuously rising, so that smaller flocs rise with the liquid and enter the primary settling zone 41 and the secondary settling zone 42 sequentially. When the liquid and smaller flocs entering the first-stage sedimentation area 41 and the second-stage sedimentation area 42 flow through the slit, the slit can prevent the smaller flocs from floating upwards, or the small flocs of multiple clusters can be gathered and then settled downwards under the action of dead weight, and meanwhile, the liquid without the flocs can continuously rise towards the upper part of the second-stage sedimentation area 42, and the liquid without the flocs can be called clear liquid. The clear liquid is a target product of the purification operation of the beneficiation wastewater.
