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 invention discloses prying-mounting equipment for treating mine wastewater. The prying-mounting equipment comprises a first lifting pump, a first-level treating unit, a second lifting pump, a second-level treating unit, a third lifting pump, a third-level treating unit, a fourth lifting pump and a fourth-level treating unit which are communicated with one another sequentially through pipelines. The first lifting pump, the second lifting pump, the third lifting pump and the fourth lifting pump are all connected with first water turbines, the prying-mounting equipment further comprises a first filter, water outlets of all the first water turbines are communicated with the first filter, the first to the fourth-level treating units and the water outlet of the first filter are all connectedwith a fifth lifting pump, the fifth lifting pump is connected with a second water turbine, and water inlets of each first water turbine and the second water turbine are connected with bottom water pipelines. The prying-mounting equipment is not provided with power, and the wastewater after being treated is directly used for production process of face; and the treating method of the mine wastewater achieves non-power in the whole driving process, conforms to the safety requirements of mine undershaft wastewater treatment, and can be widely applied.

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...
