Embodiment Construction
[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0014] The present invention as figure 1 As shown, a coal mine underground wastewater purification treatment method adopts a secondary treatment process, that is, adopts a biological treatment method to remove dissolved and colloidal organic pollutants in the coal mine underground wastewater. First, the coal mine underground wastewater passes through the grid pool 1 There are at least two grids in the grid; the waste water flows into the adjustment pool 2 after pas...

The invention provides a method for carrying out purifying treatment on coal mine underground wastewater. The method comprises the following steps that: the coal mine underground wastewater passes through at least two grids inside a grid pond; the wastewater automatically flows into a regulating pond after passing through the grids; the wastewater is lifted to an anaerobic pond by virtue of a submersible sewage pump positioned in the regulating pond; the wastewater treated by the anaerobic pond automatically flows into an anoxic pond; the wastewater which flows through the anaerobic pond is discharged into an aerobiotic pond; the wastewater from the anaerobic pond and mixed liquor which is refluxed from the aerobiotic pond and nitrified are sufficiently mixed in the anoxic pond and subjected to nitration reaction under an anoxic condition; the wastewater automatically flows into the aerobiotic pond after passing through the anoxic pond, carbonaceous organic materials contained in the wastewater are degraded, and ammonia nitrogen contained in the wastewater are nitrified. The method provided by the invention can be used for denitrifying and dephosphorizing the coal mine wastewater, thereby saving the water resources and preventing the environmental pollution.
Description
technical field [0001] The invention relates to wastewater purification and treatment technology in the field of environmental protection, in particular to a method for purification and treatment of underground coal mine wastewater. Background technique [0002] Coal mine and exhaust gas Coal mine underground wastewater is not only a source of pollution, but also a precious water resource. At present, my country's existing coal mines are seriously short of water on the one hand, and on the other hand, underground wastewater is often discharged directly into the environment without sewage treatment, causing serious damage to the environment, and at the same time seriously wasting water resources, restricting the production and production of the coal industry. The sustainable development of mining area economy, so this practical problem needs to be solved urgently. At present, the method adopted in China to treat underground coal mine wastewater generally adopts the flocculant...
