Abstract
The invention discloses a treatment system for removing nitrate nitrogen in industrial wastewater. The treatment system comprises a water-collecting well, a coarse screen, an inclined plate sedimentation pool, an aeration nitrifying pool, a high-voltage discharge organic rhodium catalytic polymerization reactive tank, a water purification pool, a weak nitrocotton drying forming system and the like. The high energy discharge capacity effect generated by high voltage arc is creatively utilized, for nitrate ions in waste water in the condition, a catalytic polymerism reaction occurs on the surface of an organic compound of transition metal element rhodium, so that ionic bonds of the nitrate ions in waste water are broken and recombined, nitrocellulose can be generated and collected, and reutilization (manufacturing of filmstrips, celluloid, nitrocellulose varnish and the like) of resources can be realized; and moreover, due the fact that the reaction is performed in a liquid base body, the reaction efficiency and speed are controlled, only weak nitrocotton is generated, and the generation of strong nitrocotton or collodion with higher nitrogen content is completely eradicated, so thatthe risk of explosion during the operation is eliminated.
Description
technical field [0001] The invention relates to a treatment system for removing nitrate nitrogen in industrial wastewater, which belongs to the field of wastewater treatment in environmental protection. Background technique [0002] Nitrate nitrogen is one of the main pollutants that pollute surface water and groundwater, and it is also the "culprit" of eutrophication in surface water. The annual amount of nitrogen fixed in the world far exceeds the amount of nitrogen released through denitrification, which leads to the accumulation of nitrate nitrogen in the water environment, and the nitrogen content of various water bodies in nature greatly exceeds the standard. [0003] At present, nitrate nitrogen pollution in the world has become more and more serious. For example, the PRIN research report in Italy shows that although the country has made great efforts to reduce nitrate nitrogen emissions from intensive agriculture, nitrate nitrogen is still one of the important pollu...
