Problems solved by technology
The invention introduces biodegradation into the conventional electrochemical system to achieve the redox effect of combining electrochemical and biodegradation, but the patent simply combines electrochemical reaction and biological reaction into one reactor, electrochemical reaction and biodegradation Biological reactions work independently, no synergistic effect is formed, and no biofilm is formed on the electrode surface
Moreover, the surface area of the electrode is small, the cathode and the anode are in two reactors respectively, and the distance between the electrodes is large, resulting in a large resistance in the entire circuit and large energy consumption.

The invention discloses a large-area electrode microbial double fluidized bed reactor, which comprises an anaerobic fluidized bed and an aerobic fluidized bed. The upper part of the anaerobic fluidized bed communicates with the aerobic fluidized bed through a filter channel; The bottom of the oxygen fluidized bed is provided with a water inlet, the upper part of the aerobic fluidized bed is provided with a water outlet, and the bottom of the aerobic fluidized bed is provided with an aeration port; the anaerobic fluidized bed and the aerobic fluidized bed are respectively An inner cylinder is provided, and the inner cylinder is a cylindrical structure open up and down, surrounded by at least four electrode plates connected in pairs, and the two opposite electrode plates are respectively connected to the positive and negative electrodes of the power supply to form a positive and negative electrode pair. The invention also discloses a wastewater treatment method based on the large-area electrode microorganism double fluidized bed reactor. The invention can greatly improve the pollutant degradation ability and efficiency.
Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to a large-area electrode microbial double fluidized bed reactor and a wastewater treatment method. Background technique [0002] The recycling of wastewater plays an important role in alleviating the shortage of urban water resources. After proper regeneration treatment, wastewater can be reused for landscape water, green irrigation, industrial cooling and other purposes to realize the reuse of water resources. Among them, high-concentration ammonia-nitrogen wastewater is one of the most difficult types of industrial wastewater to deal with. It has a wide range of sources and a large amount of discharge, which has also become one of the restrictive factors for the development of related industries. [0003] Ammonia nitrogen refers to the free ammonia (NH 3 ) and ammonium ions (NH 4+ ) in the form of nitrogen. Ammonia nitrogen is a nutrient in water, which can le...
