Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the examples in the implementation manners, other examples obtained by those skilled in the art without making creative efforts all belong to the protection scope of the present invention.

[0027] A process for recycling coal mine waste water, the steps are:

[0028] The waste water is sucked by the water pump, passes through the quartz sand filter and the activated carbon filter in turn to remove the large particle suspended matter in the water body; then enters the softening system, which includes a softening device, and a booster pump is installed in front of the softening device to ensure the softening system needs The operating pressure is...

Abstract

The invention provides a process method for reusing wastewater of a coal mine well, relating to the field of mine well wastewater treatment. The process method comprises the following steps: wastewater is pumped by virtue of a water pump and sequentially flows through a quartz sand filter and an activated carbon filter; wastewater enters a softening system and then enters a disinfection system after the total hardness of wastewater is decreased through ion exchange; a precision filter with filtration precision of 5 microns is arranged behind the disinfection system and is used for removing inactivated hyphae and other impurities, which are remained in the water body after being disinfected, by virtue of a micro-hole filter element, and effluent, which meets the water quality requirement of domestic water, of the precision filter enters a reservoir. The process method has the beneficial effects that the energy consumption is low, the investment and operation costs are low, pretreated mine water can be subjected to advanced treatment and then can be used as production and domestic water for factories, so that partial water source wells can be replaced; the water resource is effectively protected, the water resource of underground mine wells is reasonably utilized, and the wasting of the water resource is reduced.

Description

technical field [0001] The invention relates to the field of mine wastewater treatment, in particular to a process for recycling coal mine wastewater. Background technique [0002] Mine water has a series of physical, chemical and biochemical reactions in the contact of groundwater with coal seams and rock formations during the coal mining process, coupled with the impact of human activities, so the water quality has significant characteristics of the coal industry: mine water containing suspended solids The content of suspended solids is much higher than that of surface water, and the sensory properties are poor; and the suspended solids contained have small particle size, light specific gravity, slow settling speed, and poor coagulation effect; mine water also contains organic pollutants such as waste engine oil and emulsified oil. The total ion content contained in mine water is much higher than that of general surface water, and a large part is sulfate ion. Mine water o...
