Description
Technical Field
The invention relates to a device for treating landfill leachate membrane concentrated solution, in particular to a device for treating landfill leachate membrane concentrated solution based on electrooxidation coupling electrocoagulation.
Background
At present, the electric flocculation device generally has the defects that a large reaction polar plate is needed in the using process, or the reaction time is long, and air floatation pollutants can enter a solution again, organic pollutants cannot be completely removed by single electric flocculation, a combined process is needed for treatment, however, the total mass transfer efficiency between serially connected combined process reactors is low, the occupied area is increased, the energy consumption is increased, the connection between a corrosion electrode and an external power supply and the connection between electrodes are generally connected by using a lead, contact corrosion can be generated at the connection part in the system operation process, further, the corrosion of a working electrode in the electric flocculation device is accelerated, the problems that the contact at the electrode connection part is poor and the like are easily caused, and the normal operation of a circuit is influenced. These problems increase the complexity of the production operation and maintenance of the electroflocculation plant and the operational stability of the system.
The single electrooxidation process is adopted to treat the high-concentration organic wastewater, and although the removal of low-valence ions and the mineralization of refractory organic matters (such as humic acid and fulvic acid) can be realized, the problems of low electrooxidation efficiency and large energy consumption exist. Even with the coupled electrocoagulation reactor, the traditional vertical polar plates are perpendicular to the direction of an electric field, so the reactor structure needs large reaction polar plates and high current density, and the flocculant generated in situ is often insufficient to treat large-flow industrial wastewater.
Aiming at the current ubiquitous practical bottleneck problem, more 'flocculating agents' need to be generated in situ, generated air-flotation pollutants are timely removed in a simple mode, the treatment effect is enhanced through process coupling, and a lead is not adopted to connect a polar plate. Although patents report a method of enhancing the in-situ generation of more "flocculants" by electrocoagulation and a bipolar generation method of electrocoagulation such as (patent CN107459113A — a radio flocculation water treatment device based on bipolar electrochemical principle), the horizontally disposed bipolar electrocoagulation electrode is easy to accumulate flocculated sediments, so that the amount of flocculants generated in situ in the electric field is greatly reduced, and the device has no way to mix and adsorb the generated flocculants with the pollutants in the solution in time to effectively generate flocs. Although the flocculation process of coupling electrooxidation is reported in documents or patents, the process needs to be controlled by additional drugs and more processes, which consumes manpower and material resources and increases the cost.
