Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a mine sewage filtering and treatment device. Background Art

[0002] During the coal mining process, groundwater comes into contact with coal seams and rock strata, and due to the influence of human activities, a series of physical, chemical and biochemical reactions occur and penetrate into the tunnels to produce a large amount of mine wastewater.

[0003] The use of mining equipment and devices also causes organic pollutants such as waste oil and emulsified oil to be mixed into mine water. When treating mine sewage, NaOH and lime milk are first added to the sewage to remove sewage hardness, turbidity and suspended matter, and increase the alkalinity of the water; then PAC and PAM are added for flocculation and precipitation. After adding the treatment reagent, the reagent is directly added to the treatment pool through the dosing pipe. The discharge area of ​​the dosing pipe outlet is small, and the added reagent is concentrated in a certain area in the pool, resulting in diffusion taking time.

[0004] In view of this, we propose a mine wastewater filtration and treatment device. Utility Model Content
