Abstract

The present invention discloses one kind of mine water deeply purifying method and apparatus capable of purifying mine water to reach drinking water standard and utilizing mine water resource effectively. The method includes two parts, flocculating and microfiltering, and nanofiltering; and the corresponding apparatus includes a flocculating and microfiltering reactor and a nanofiltering film filter mainly. The main technological conditions include flocculant throwing amount of 5-30 mg / L, filtering diameter of the microfiltering film of 0.1-10 micron, negative pressure for sucking of 0.05-0.2 MPa, the MgSO4 intercepting rate of the nanofiltering film of 95.0-99.0 %, and operation pressure of 0.4-1.0 MPa. The present invention can realize automatic control and mobile treatment, and is suitable for deep purifying treatment of different types of mine water.

Description

technical field

[0001] The invention relates to a method and device for deep purification of waste water, in particular to a method and device for deep purification of mine water. Background technique

[0002] Mine water is the groundwater that gushes out during the coal mining process. It is collected into the underground water tank through various underground ports and then discharged to the ground above the well. Most mining areas in my country are severely water-scarce areas. Reuse of mine water for life and production after advanced treatment can not only greatly alleviate the environmental pollution of mine water, but also open up new water sources for mining areas and greatly alleviate the water shortage in mining areas. contradiction.

[0003] Mine water quality is affected by geological conditions, coal seam characteristics, coal mining technology and other factors. Among them, mine water containing suspended solids and mine water with high salinity are the most co...
