Description
Technical Field
The utility model belongs to the technical field of waste water treatment, concretely relates to electrochemical reaction pond suitable for heavy metal wastewater treatment.
Background
The working principle of the electrochemical sewage treatment is as follows: under the action of external voltage, cations generated by a soluble anode (usually an iron anode or an aluminum anode) are hydrolyzed and polymerized in a solution to generate a series of polynuclear hydroxyl complexes and hydroxides, the polynuclear hydroxyl complexes and the hydroxides serve as a flocculating agent to play a role in flocculation, and the generated complex ions and the hydroxides have high adsorption activity and higher adsorption capacity than hydroxides obtained by hydrolysis by a general medicament method. It can effectively adsorb organic pollutant and other colloidal substances in water. Meanwhile, because water is dissociated and other substances are electrolyzed and oxidized, tiny bubbles of oxygen and hydrogen are generated on the anode and the cathode, the bubbles have good adhesion performance, and can bring agglomerated micelles and suspended matters generated in the electrolysis process to the water surface. During the electrolysis, electrolytic redox reactions also occur, which are classified into direct redox and indirect redox. Direct redox refers to the removal of contaminants from wastewater by direct oxidation or reduction at the electrodes; indirect redox refers to the production of redox species during electrolysis as a reactant or catalyst to convert contaminants into less toxic species, such as nascent hydrogen and active oxygen produced during water dissociation, and other strong oxidants or free radicals. By oxidation, some of the macromolecular organic matter in the solution is decomposed into small molecular organic matter and may be directly oxidized into CO 2 And H 2 O does not produce sludge, and the small molecular organic matters can be effectively separated under the subsequent flocculation and air flotation actions; heavy metals can be recovered by the reduction of nascent hydrogen produced at the cathode, and halogenated hydrocarbons, substances with benzene rings, and the like can be reduced. Therefore, in the process of treating wastewater by electric flocculation, various processes simultaneously act, and pollutants are easily removed by these actions.
At present, the electrochemical technology is not widely applied in a large scale, and the main reason for restricting the wide application is that the energy consumption is high, the soluble anode is easy to polarize and passivate, so that the treatment power consumption is increased, the treatment effect is reduced, the polar plate needs to be replaced frequently at regular intervals in practical application, and the polar plate is troublesome to replace due to the structural design and has large workload.
