Efficient rotational flow multistage purification device for mine wastewater treatment

Abstract

The invention relates to an efficient rotational flow multistage purification device for mine wastewater treatment, and belongs to the field of mine wastewater treatment. Mine wastewater containing suspended matters is mixed with a medicament and then enters the device through a water inlet pipe, and deep coagulation of the medicament and the wastewater is carried out through cyclone mixing and centrifugal separation effects of a cyclone center cylinder; meanwhile, under the combined action of the gravity field, the ascending water flow and the rotating flow field, suspended solids in the wastewater form a sludge layer area at the bottom of the inner cavity, and the water flow forms a flow field change from ascending to descending along the center to the barrel wall; after the ascending suspended matters are filtered by the sludge layer, the special-shaped inclined plate and the filter material layer, and clear water is discharged through a water discharging pipe; and after the separated sludge is concentrated by the sludge concentration device, one path is discharged through a sludge discharge pipe, and the other path is pressurized by a high-density circulating pump to enter a water inlet pipe to be mixed with inlet water, so as to finish a high-density circulating function.

Description

technical field [0001] The invention relates to a high-efficiency cyclone multi-stage purification device for mine wastewater treatment, belonging to the field of mine wastewater treatment. Background technique [0002] With the rapid development of industry, waste water and sewage are increasing rapidly, and the pollution of water bodies is becoming more and more extensive and serious, threatening human health and safety. At present, the commonly used mine wastewater purification equipment has the following main disadvantages: [0003] 1. The technology is single, and the best treatment effect cannot be exerted; [0004] 2. It occupies a large area and wastes land resources; [0005] 3. Inconvenient operation, high cost of labor and medicine; [0006] 4. There are many maintenance items and the service life is limited. Contents of the invention [0007] The technical problem to be solved by the present invention is to provide a high-efficiency cyclone multi-stage puri...
