Embodiment 1
[0009] Example 1: A method for treating glyphosate wastewater that reduces carbon dioxide emissions. Glyphosate wastewater is prepared from glyphosate by the iminodiacetic acid method. After the oxidation of diglyphosate is completed, the extracted glyphosate is Wastewater, (1) add alkali to adjust pH in glyphosate wastewater, control pH=3~5, obtain corresponding formate solution; (2) the solution of step (1) is concentrated and separated by membrane integration method, and the mass fraction obtained is 5% to 25% formate solution and 0.5% to 5% formaldehyde aqueous solution with a mass fraction of ①; (3) The formate solution in step (2) is evaporated and dehydrated by steam and solid-liquid separation to obtain formate wet powder and formaldehyde aqueous solution with a mass fraction of 0.5% to 5% ②, the formate wet powder is dried to obtain the finished product; (4) the formaldehyde aqueous solution is added to ammonia according to 0.15% to 3% of the mixed weight of ① and ② to...
Embodiment 2
[0010] Example 2: On the basis of Example 1, (1) add alkali to the glyphosate wastewater to adjust the pH, control the pH=3, and obtain the corresponding formate solution; (2) the solution of step (1) adopts the membrane integration method Concentrate and separate to obtain a formate solution with a mass fraction of 5% and an aqueous formaldehyde solution with a mass fraction of 0.5% ①; (3) the formate solution in step (2) is evaporated and dehydrated by steam, and separated from solid and liquid to obtain formate Wet powder and formaldehyde solution with a mass fraction of 0.5% ②, the formate wet powder is dried to obtain the finished product; (4) add ammonia to the formaldehyde solution according to 0.15% of the mixed weight of ① and ② to obtain a mass fraction of 0.3% The urotropine aqueous solution, and then the urotropine was concentrated to 10% by membrane separation.
Embodiment 3
[0011] Embodiment 3: On the basis of embodiment 1, (1) add alkali to adjust pH in glyphosate waste water, control pH=5, obtain corresponding formate solution; (2) the solution of step (1) adopts membrane integration method Concentrate and separate to obtain a formate solution with a mass fraction of 25% and a formaldehyde solution with a mass fraction of 5% ①; (3) the formate solution in step (2) is evaporated and dehydrated by steam, and separated from solid and liquid to obtain formate Wet powder and formaldehyde solution with a mass fraction of 5% ②, the formate wet powder is dried to obtain the finished product; (4) Add ammonia to the formaldehyde solution according to 3% of the mixed weight of ① and ② to obtain a mass fraction of 4% The urotropine aqueous solution is then separated by membrane to concentrate the urotropine to 25%.
