Embodiment 1
[0078] This embodiment is a device for eliminating foam in mineral processing wastewater.
[0079] figure 1 It is the structural representation of the elimination device of foam in the mineral processing wastewater of the present invention, as figure 1As shown, the device for eliminating foam in mineral processing wastewater in this embodiment includes: a wastewater storage unit 1 , an ozone storage unit 2 , a reaction unit 3 , a flow detection unit 4 and an ozone generation unit 5 .
[0080] Wherein, the outlet of the waste water storage unit 1 is communicated with the inlet of the reaction unit 3, the outlet of the ozone storage unit 2 is communicated with the inlet of the flow detection unit 4, the outlet of the flow detection unit 4 is communicated with the inlet of the reaction unit 3, and the outlet of the ozone storage unit 2 is connected with the inlet of the reaction unit 3. The inlet communicates with the ozone generating unit 5 .

Embodiment 2
[0086] This example eliminates the foam in the andalusite ore flotation wastewater. Before the elimination, the following pretreatment and detection of the foam height are sequentially performed on the andalusite ore flotation wastewater.
[0087] Pretreatment: inject the andalusite ore flotation wastewater directly generated by the mine into the settlement tank on the mine site, and make the andalusite ore flotation wastewater settle naturally in the settlement tank until the water quality in the upper layer is clear and there are no impurities visible to the naked eye. The upper clarified andalusite ore flotation wastewater is collected as raw material for foam elimination.
[0088] Detection of foam height: Use an oscillator to oscillate the above-mentioned andalusite ore flotation wastewater after pretreatment, wherein the oscillation frequency of the control oscillator is 280 times / min, and the oscillation time is 1min. In the end, the height exceeds 1cm and Foam that doe...
Embodiment 3
[0101] In this embodiment, the foam in the kyanite ore flotation wastewater is eliminated. Before the elimination, the kyanite ore flotation wastewater is subjected to the following pretreatment and foam height detection in sequence.
[0102] Pretreatment: inject kyanite ore flotation wastewater directly generated in the mine into the settlement tank on the mine site, so that the kyanite ore flotation wastewater will naturally settle in the settlement tank until the water quality in the upper layer is clear and there is no visible to the naked eye. Impurities, the upper clarified kyanite ore flotation wastewater is collected as a raw material for eliminating foam.
[0103] Detection of foam height: use an oscillator to oscillate the above pretreated kyanite ore flotation wastewater, wherein the oscillation frequency of the control oscillator is 280 times / min, the oscillation time is 1min, and finally, the height exceeds 1cm And the foam that does not defoam within 30s.
