Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a coal mine water gushing pickling wastewater purification treatment device, wherein a stirring mechanism can make the wastewater and the alkaline solution roll up and down, and at the same time can flow along the rotating direction of the stirring plate, so that the wastewater and the alkaline solution are fully mixed, thereby adjusting the pH value of the wastewater; the inclined tube sedimentation mechanism and the inclined plate sedimentation mechanism can accelerate the sedimentation speed of impurities in the wastewater, and the cleaning mechanism can clean the sludge adhered inside the inclined tube; that is, the inclined tube can be prevented from being blocked and the sedimentation speed of the inclined tube can be accelerated.
