The invention provides a coal-electricity integrated wastewater resource recycling method and system, including a V-shaped filter tank, a first-level self-cleaning filter, a first-level ultrafiltration device, a first-level reverse osmosis device, a high-density sedimentation tank, and a multi-media Filter, secondary self-cleaning filter, secondary ultrafiltration device, secondary reverse osmosis device, inclined plate sedimentation tank, power plant wastewater buffer tank, triple box and tubular ultrafiltration membrane, the present invention aims to solve the problem of power plant desulfurization wastewater and coal mine The problem of high equipment cost and operating cost caused by the separate treatment of mine water, the bicarbonate in the coal mine water is retained through fine dosing and softening treatment, and then the concentrated and reduced coal mine water concentrate and desulfurization wastewater are processed to soften together. Make the sulfate and bicarbonate in coal mine water fully participate in the precipitation reaction of calcium ions in the softening treatment of desulfurization wastewater, and apply it to the treatment of production wastewater in coal-electricity integration enterprises to achieve zero discharge of wastewater, and provide engineering design and engineering practice. guide. |
