A water-mediated advanced oxidation reaction process, including: wastewater enters a pretreatment device, suspended particulate matter is removed by oxygen, odor, chroma, germs and organic matter are partially removed, and water is reoxygenated; then the effluent enters advanced The reduction device removes odor, chroma, bacteria and organic matter again through hydrogen, and reduces the organic matter that is easy to reduce and hard to oxidize into intermediate products by active hydrogen; then the effluent enters the advanced oxidation device, and is produced by the reaction of hydrogen peroxide and Fe(II) The ROS will mineralize the organic matter in the water; then the effluent enters the sedimentation tank to separate the mud and water, and then the effluent reaches the standard; the sedimented sludge is sent to the concentration tank, and the iron sludge in the concentration tank enters the activation tank, and is activated by hydrogen and catalyst to Fe(II) Then recirculated to the advanced oxidation device. The invention uses the water in the wastewater as the medium during self-purification treatment, and has the advantages of high efficiency, environmental friendliness, no secondary pollution and the like during the restoration of the organic-contaminated water body. |
