Embodiment 1
[0036] Limonite was pulverized and sieved to obtain 100-mesh particles. The particles were soaked in concentrated hydrochloric acid and saturated potassium hydroxide methanol solution in sequence, and separated. Then, oxymalononitrile was added to the obtained precipitate for polarization. After pickling, alkali leaching and polarization, the nanomaterials were immersed in an organic composite solvent, stirred for 30 minutes, washed with deionized water for 3 times after precipitation, dried, stirred for 15 minutes and then separated. Methyl tert-butyl ether 30g, ring 40g of oxyethane and 30g of octanal are formulated as an organic compound denitrification agent to treat urine wastewater in a certain place. The dosage of nanomaterials is 50ppm, and the pH of the wastewater is adjusted to 12. The concentration of ammonia nitrogen in the wastewater is reduced from 9000mg / L to 0.4 mg / L, the removal rate of ammonia nitrogen is above 99.9%.
Embodiment 2
[0038] Limonite was crushed and sieved to obtain 110-mesh particles. The particles were soaked in concentrated hydrochloric acid and saturated potassium hydroxide methanol solution in sequence, and separated, and then oxymalononitrile was added to the obtained precipitate for polarization. After pickling, alkali leaching and polarization, the nanomaterials were immersed in an organic composite solvent, stirred for 40 minutes, washed with deionized water for 3 times after precipitation, dried, stirred for 20 minutes, and then separated. Ethyl vinyl ether 20g, 30g of trityl alcohol, 20g of n-butanol, 10g of alkenal, and 20g of ethylene oxide are formulated as an organic compound denitrification agent to treat the urine wastewater of a certain community. The dosage of nanomaterials is 80ppm, and the pH of the wastewater is adjusted to 11.5. The concentration of ammonia nitrogen in the wastewater is reduced from 7000mg / L to 0.2mg / L, and the removal rate of ammonia nitrogen is over ...
Embodiment 3
[0040] Limonite was crushed and sieved to obtain 120-mesh particles. The particles were soaked in concentrated hydrochloric acid and saturated potassium hydroxide methanol solution in sequence, and separated. Then, oxymalononitrile was added to the obtained precipitate for polarization. After pickling, alkali leaching and polarization, the nanomaterials were immersed in an organic composite solvent, stirred for 60 minutes, washed with deionized water for 3 times after precipitation, dried, stirred for 30 minutes, and then separated. Methyl tert-butyl ether 10g, 10g of ethylene oxide, 20g of octanal, 20g of trityl alcohol, 10g of n-butanol, 10g of alkenal, 10g of decanal, and 10g of ethyl vinyl ether were formulated as an organic compound denitrification agent to treat urine wastewater in a certain area. For treatment, the dosage of nanomaterials is 100ppm, the pH of wastewater is adjusted to 12, the concentration of ammonia nitrogen in wastewater is reduced from 10000mg / L to 0....
