Water treatment all-in-one machine equipment for coal mine

Abstract

The invention discloses water treatment all-in-one machine equipment for a coal mine. The water treatment all-in-one machine equipment comprises a settling tank, a fiber ball filter, a security filter and a dosing filter box, wherein a water inlet in the lower part of each settling tank is connected with a water pump of a mine sump or a drainage gate road through a pipeline and takes water from the water pump; a plurality of layers of filter screens which are stacked up and down are arranged in each settling tank; a water inlet in the upper part of the fiber ball filter is communicated with a water outlet in the upper part of the settling tank; a plurality of layers of fiber ball filter plates which are stacked vertically are arranged in each fiber ball filter; the security filter is connected with a water outlet in the lower part of the fiber ball filter; a filter element is arranged in the security filter; a water inlet of the dosing filter box is communicated with a water outlet of the security filter, each dosing filter box internally comprises a plurality of filter layers which are arranged in parallel left and right, and the filter layers have different filter functions; wherein the water treatment all-in-one machine equipment can be used for comprehensively treating underground wastewater conveyed by a water pump of a mine sump or a drainage crossheading. Therefore, the equipment has better purification treatment capacity.

Description

technical field [0001] The invention relates to the field of mine sewage treatment, in particular to an integrated water treatment equipment used in coal mines. Background technique [0002] With the increasingly stringent environmental protection requirements in our country, the treatment facilities of water treatment plants cannot fully meet the environmental protection discharge requirements, and it is difficult to achieve the development of local environmental protection. Especially in nature reserves, it is necessary to further improve the quality of mine water to create conditions for environmental protection, so that the quality of effluent water can meet the "Environmental Quality Standards for Surface Water". [0003] In the prior art, the treatment of coal mine wastewater generally includes two processes of sedimentation and filtration. It is difficult to ensure the removal of fluoride ions, ammonia nitrogen, hexavalent chromium and borate contained in sewage only ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the treatment of coal mine waste water generally includes two processes of sedimentation and filtration. It is difficult to ensure the removal of fluoride ions, ammonia nitrogen, hexavalent chromium and borate contained in sewage only by sedimentation and filtration.

In addition, due to the limitation of mine environment and space, it is difficult to arrange large-scale sewage treatment equipment, so it is difficult to achieve large-scale water purification

There may also be various bacteria, viruses, parasites, algae and other pathogens in the sewage generated by coal mines, and the treatment process is complicated.

[0004] Existing water treatment equipment mostly treats sewage through a combination of multiple equipment, but the combination of multiple equipment is easily affected by the processing capacity, processing speed and service life of different equipment, it cannot be flexibly arranged, and the treatment effect is not ideal
