Modular nano confined electrocatalytic oxidation equipment
Modular nano restricted electrocatalytic oxidation equipment is an intensive and efficient wastewater treatment equipment. It is an equipment that integrates functions such as decarbonization, denitrification, complex breaking, and precious metal reduction. The equipment is simple, small in size, occupies a small area, consumes only clean energy and electrical energy, and has strong applicability. It is an environmentally friendly and resource-intensive environmental protection equipment.
Equipment features
Modular design: determine the number of modules according to the size of water volume and water quality, and it is easy to install
Fully automatic operation: small size, simple and easy operation of the system, less maintenance, high efficiency, and can be unattended
Green and pollution-free: it only consumes clean energy and electrical energy, does not need to consume a lot of chemicals, and does not cause secondary pollution
Wide range of applications: according to the characteristics of different types of wastewater, the equipment structure and process parameters can be flexibly adjusted.
Applicability
Toxic and harmful organic wastewater and high-chlorine organic wastewater and other internationally recognized difficult-to-degrade wastewater: the treatment effect is excellent, and the COD removal rate can reach more than 95%.
Standard improvement and transformation of direct drainage: It can ensure that the COD of external drainage reaches the first-level B standard.
Wastewater from heavy metal organic complexes in leather, printing and dyeing industries: oxidation breaks the network, combined with redox, chemical precipitation, flocculation and sedimentation processes, it can ensure that the heavy metal content of the treated wastewater meets the discharge requirements, and heavy metal sludge can be recovered for resource utilization.* Width: 4.5mm-1000mm
Principle
Under the action of an external electric field, most pollutants lose electrons under the domain-limiting catalytic effect of the nano-anode and are directly oxidized; a small number of pollutants are indirectly oxidized by intermediate products with strong oxidation effects (such as ·OH and other free radicals) generated by the anode reaction. At the same time, the reduction reaction of nitrate and (heavy) metal ions will also occur at the cathode, which realizes denitrification and the recovery of metal elements.
