Embodiment 1
[0048] The vanadium extraction wastewater was selected from a vanadium precipitation wastewater roasted with sodium slag, and the water-liquid property regulator was selected from commercially available monoethanolamine, NO X Triethanolamine is selected as the reducing agent, and hydrazine hydrate is selected as the denitrification accelerator. According to the following steps, ammonia-hydrocarbon denitrification agent (referred to as denitrification agent) is directly prepared from vanadium extraction wastewater as the main raw material:
[0049] (1) Adjust the properties of the vanadium extraction wastewater: put the vanadium extraction wastewater in a stirring tank, add ethanolamine, an aqueous liquid property regulator, to adjust the pH value to 6.1, and obtain solution A;
[0050] (2) Preparation of ammonia-hydrocarbon denitrification agent: use the obtained solution A as the main raw material and NO X The reducing agent triethanolamine and the denitrification accelerato...
Embodiment 2
[0052] Vanadium-extracting wastewater was selected from vanadium-containing wastewater roasted by sodium-containing stone coal, and the water-liquid property regulator was selected from commercially available N-methyl monoethanolamine, NO X Commercially available ammonium carbonate and isopropanol are selected as the reducing agent, and carbohydrazide is selected as the denitrification accelerator. According to the following steps, ammonia-hydrocarbon denitrification agent (referred to as denitrification agent) is directly prepared from vanadium extraction wastewater as the main raw material:
[0053] (1) Adjust the properties of the vanadium extraction wastewater: put the vanadium extraction wastewater in a stirring tank, add N-methyl monoethanolamine to adjust the pH value to 6.3, and obtain solution A;
[0054] (2) Preparation of ammonia-hydrocarbon denitrification agent: use the obtained solution A as the main raw material and NO XThe reducing agent ammonium carbonate, is...
Embodiment 3
[0056] The vanadium extraction wastewater was selected from a factory that used a fluidized bed furnace to roast vanadium-containing stone coal without salt, and the water-liquid property regulator was selected from commercially available ammonium carbonate, NO X Commercially available ammonia water (27% mass concentration) and glucose (waste liquid) were selected as the reducing agent, and hydrazine hydrate was selected as the denitrification accelerator. According to the following steps, the ammonia-hydrocarbon denitrification agent is directly prepared from vanadium extraction wastewater as the main raw material:
[0057] (1) Adjust the properties of the vanadium extraction wastewater: put the vanadium extraction wastewater in a stirring tank, add ammonium carbonate, an aqueous liquid property regulator, to adjust the pH value to 7.8, and obtain solution A;
[0058] (2) Preparation of ammonia-hydrocarbon denitrification agent: the obtained solution A is used as the main raw...
