Embodiment 1

[0044] A drain hole is drilled in the coal seam, and the bottom water of the coal seam with a pressure of 1.5Mpa to 3.0Mpa is collected through the bottom water pipeline 13 and transported to the first water turbine 9 and the second water turbine 12 to drive the first lift pump 1 and the second water turbine respectively. Lift pump 3, third lift pump 5, fourth lift pump 7 and fifth lift pump 11; mine sewage with turbidity of 80-300 (NTU) and COD of 60mg / L-90mg / L passes through the first lift pump 1 Sequentially enter the first dosing device 14 and the first pipeline mixer 15 equipped with treatment agent A, and the water from the first pipeline mixer 15 enters the second pipeline mixer 17 through the second dosing device 16 equipped with treatment agent B , and mixed with the treatment agent B in the second pipeline mixer 17, after mixing, it enters the primary hydrocyclone 18 for centrifugal sedimentation, and the outlet water of the primary hydrocyclone 18 enters the secondar...

Abstract

The skid-mounted equipment for treating mine sewage disclosed by the present invention comprises a first lift pump, a first-level treatment unit, a second lift pump, a second-level treatment unit, a third lift pump, a third-level treatment unit, The fourth lifting pump, the fourth-stage processing unit, the first lifting pump to the fourth lifting pump are all connected to the first water turbine, and also include the first filter, and the water outlets of all the first water turbines are connected to the first filter, and the four-stage The water outlets of the processing unit and the first filter are connected with the fifth lift pump, and the fifth lift pump is connected with the second water turbine, and the water inlet of each first water turbine and the second water turbine is connected with a bottom water pipeline. The installed equipment has no power supply, and the treated water is directly used in the production process of the mining face; the mine sewage treatment method of the present invention realizes the power without power supply in the entire driving process, meets the safety requirements for sewage treatment in coal mines, and can be widely used.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a skid-mounted equipment for treating mine sewage, and also relates to a method for using the equipment to treat mine sewage. Background technique [0002] Coal accounts for more than 70% of my country's energy structure. During the coal mining process, a large amount of waste water will be generated due to production needs such as dust prevention and equipment cooling. The water contains a large amount of dust and minerals. If it is discharged directly without treatment, it will cause water resources Waste, unable to achieve sustainable development of coal production. The main characteristics of coal mine sewage water quality are as follows: (1) The main components of suspended solids in mine water are coal powder and rock powder, and their content is generally tens to hundreds of milligrams per liter; (2) The suspended solids in mine water have small particl...
