AI Technical Summary

Technical Problem

Existing technologies are unable to effectively address the high viscosity problem caused by montmorillonite particles in underground sludge in mining areas, resulting in the inability of transition layer particles to float to the surface after sludge stratification, affecting the treatment effect.

Method used

A device for treating underground sludge in mining areas is designed. It uses a combination of a conical barrel, a toggle plate and fly ash slurry to treat the sludge through standing, stirring and aeration, thereby reducing the viscosity and allowing the particles to float and be collected.

Benefits of technology

The preliminary treatment of sludge was achieved, the viscosity was reduced, the particles were successfully collected from the sludge surface, and the treatment efficiency was improved.

Abstract

The invention relates to the technical field of wastewater treatment, in particular to a mining area underground sludge treatment device which comprises a composting bed, a rack and a water pump, the rack is located on one side of the composting bed, a lead screw structure is arranged at the upper end of the inner side of the rack, a supporting frame is fixed to one side of a conical barrel, a containing box is fixed to the inner side of the supporting frame, and the water pump is arranged in the containing box. Fly ash slurry is contained in the containing box, an L-shaped flow channel is formed in the upper end of the inner side of the stirring plate, the flow channel is communicated with the interior of the containing box through a conveying pipe, and an electric control valve is arranged on the conveying pipe. The sludge is injected into the composting bed, after standing, liquid on the upper layer is pumped away, the pumped water is subjected to primary treatment, then, fly ash slurry is slowly added into the sludge on the lower layer, so that the viscosity of the sludge can be reduced, and in the aeration heating process, the sludge can be uniformly dispersed in the sludge; the particles in the transition layer are adsorbed by the microbubbles and successfully float upwards to the surface of the sludge for collection, so that the primary treatment of the underground collected sludge is completed.
