Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0031] Such as figure 1 As shown, an integrated mine water purification system of the present invention, the system includes a pipeline mixer connected sequentially from front to back, a grid reaction flocculation tank, a high-density reverse sedimentation tank, a valveless filter tank and a clear water tank;

[0032] The system includes the following process steps:

[0033] S1: Mine wastewater enters the pipeline mixer, contacts and mixes with the composite flocculant added to the pipeline mixer, the residence time is 5-8s, and the flow rate is 0.7-1.0m / h;

[0034] S2: Mine wastewater flows into the grid reaction flocculation tank by itself after passing through the pipeline mixer. Under the action of the grid and eddy current in the network reaction flocculation tank, it fully reacts with the flocculant, the residence time is 8-15min, and the flow...

Abstract

The invention discloses an integrated mine water purification system which comprises a pipeline mixer, a grid reaction flocculation tank, a high-density reverse sedimentation tank, a valveless filter tank and a clear water tank which sequentially communicate from front to back; mine wastewater sequentially enters the pipeline mixer and the grid reaction flocculation tank, silt, suspended matters and heavy metal ions are removed and then the treated water automatically enters the high-density reverse sedimentation tank, suspended matters in the purified water A are removed, and then the treated water automatically enters the valveless filter tank, and after micro suspended matters and microorganisms are removed, the treated water automatically enters the clean water tank. The integrated mine water purification system is energy-saved and has small water inlet energy consumption and saves the washing water amount, is high in efficiency, higher in volume utilization rate, smaller in occupied area, reasonable in structure and convenient to operate and manage.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated mine water purification system. Background technique [0002] Mine water, as a precious water resource, has good economic, environmental and social benefits if it is treated and recycled. [0003] In the prior art, the mine water is firstly purified, and then the purified water is softened. Among them, the water softening methods include ion exchange, electrodialysis, and reverse dialysis. [0004] However, in the prior art, the mine water treatment process is complicated, the energy consumption is high, and the treatment cost is high. Contents of the invention [0005] The purpose of the present invention is to solve the above problems and provide an integrated mine water purification system with reasonable structure and low energy consumption. [0006] In order to solve the above technical problems, the technical solution of the present in...
