Problems solved by technology

The biological denitrification process has low operating costs and is currently the most widely used denitrification technology. However, the biological denitrification process has a limited effect on the removal of ammonia nitrogen. Because high-ammonia nitrogen wastewater will have a toxic effect on microorganisms in the water, it is only suitable for low- and medium-concentration wastewater. deal with

Abstract

The invention relates to a multi-chamber multidimensional electro-coagulation apparatus for high ammonia nitrogen wastewater. The multi-chamber multidimensional electro-coagulation apparatus comprises: an electro-coagulation apparatus shell; a high voltage pulse power supply; anode plates, cathode plates, separator plates, particle electrodes and aeration areas which are arranged in the shell; and auxiliary assemblies arranged on the shell, wherein the anode plates and the cathode plates are respectively provided with a composite catalyst coating layer, and are respectively connected with the positive electrode and the negative electrode of the high voltage pulse power supply. The multi-chamber multidimensional electro-coagulation apparatus adopts the high voltage pulse power supply as an apparatus power supply, and spaces between the cathode plates and the anode plates are filled with the particle electrodes, so the energy consumption is greatly reduced, the specific surface area of the electrodes are increased, and the current efficiency is improved; and micro bubbles generated in the electrolysis process have an air flotation effect, so the wastewater treatment effect of the apparatus is totally greatly improved. The apparatus has the advantages of convenient operation, integration electro-coagulation, electro-catalysis and air flotation, and realization of continuous multistage treatment of wastewater through multiple chambers.

Description

technical field [0001] The invention relates to a high ammonia nitrogen wastewater treatment device, in particular to a multi-chamber multidimensional electrocoagulation device for high ammonia nitrogen wastewater. Background technique [0002] In recent years, with the strengthening of environmental protection, COD, the representative indicator of organic matter in water, has been effectively controlled, but the discharge of high ammonia nitrogen wastewater has not been effectively controlled, and the discharge of untreated nitrogen-containing wastewater has caused environmental damage. Great harm, such as easy to cause eutrophication of lakes, ocean red tides, etc. After a preliminary search, the current treatment methods for ammonia nitrogen wastewater mainly include blow-off method, chemical oxidation, biological denitrification process-nitration / denitrification method; the blow-off method is to remove the ionic ammonium (NH 4 + ), which is converted into molecular amm...
