Description
Technical Field

Background
The black and odorous water body is caused by serious oxygen deficiency of the water body and deterioration of the ecological environment of the water body due to overhigh concentration of organic pollutants in the water body. The existing bioremediation method is a common method for treating black and odorous water, and comprises aeration, oxygenation, ecological floating islands and the like, and the metabolism of microorganisms is utilized to degrade organic matters in the water. However, when the water body is severely black and odorous, the bioremediation efficiency is low at the early stage of black and odorous water body treatment due to poor biodegradability of the water body.
The electrochemical oxidation method is characterized in that an electrode reaction is generated through an applied voltage, a substance with strong oxidizing property is formed on the surface of the electrode to oxidize water pollutants, and the generated substance with strong oxidizing property mainly comprises Reactive Oxygen Species (ROS), reactive Halogen Species (RHS) and other active groups, such as S 2 O 8 2- 、•SO 4 - 、•PO 4 2- 、C 2 O 6 2- And the specific generation of which strongly oxidizing species depends on the electrode and electrolyte species. ROS has the formula OH, O 3 、O 2 - Etc. RHS has Cl 2 、ClO - And so on. These strongly oxidizing compounds further oxidatively decompose organic contaminants on the surface of the anode. In the electrochemical oxidation process, the surface of the cathode electrode is subjected to reduction reaction, and dissolved oxygen can be reduced into H 2 O 2 The rate is related to the dissolved oxygen content of the water body.
In electrochemical oxidation processes, the efficiency of contaminant degradation is primarily related to the rate of mass transfer of the contaminant to the electrode surface and the yield of strongly oxidizing compounds. The electrochemical oxidation method is widely researched in the fields of chemical wastewater, landfill leachate and the like, but is not applied in the field of black odorous water treatment. In coastal cities, the salt content of urban river channels is high, the salt content of water is between 0.7 and 1.1 percent, the water has certain conductivity, and the water Cl - The content is high, so that the electrochemical oxidation technology can be well applied to the repair of the brackish black and odorous water body.
