Embodiment 1
[0029] Get 5kg of by-product salt obtained on the glyphosate production route prepared by glycine method, clean with cleaning agent, control the mass ratio of cleaning agent consumption and solid salt to be 1:1, the cleaning time is 30min, and the number of times of cleaning is 1 time, and then Vacuum filtration was performed to obtain a solid salt. The solid salt was reconstituted into a solution with a NaCl content of 300g / L. The total organic carbon TOC measured was 158.6mg / L, the total nitrogen TN was 29.05mg / L, and the TP was 93.2mg / L.
[0030] Adjust the pH of the prepared brine to 10 with 1mol / L NaOH, and then conduct nanofiltration membrane separation, control the membrane inlet pressure at 2.0MPa, the temperature at 13.1±2°C, and the concentration ratio of the nanofiltration membrane is 5 times by mass When the nanofiltration membrane separation is stopped. The measured total organic carbon (TOC) of nanofiltration membrane weak liquid is 26.29mg / L, total nitrogen (TN...
Embodiment 2
[0033]Get 5kg of by-product salt obtained on the glyphosate production route prepared by glycine method, clean with cleaning agent, control the mass ratio of cleaning agent consumption and solid salt to 7:5, the cleaning time is 20min, and the number of times of cleaning is 1 time, and then Vacuum filtration was carried out, and the solid salt was obtained after vacuum drying. The solid salt was reconstituted into a solution with a NaCl content of 300g / L. The total organic carbon TOC was measured to be 301.45mg / L, the total nitrogen TN was 53.97mg / L, and the TP was 185mg / L.
[0034] Adjust the pH of the prepared brine to 10 with 1mol / L NaOH, and then conduct nanofiltration membrane separation, control the membrane inlet pressure at 2.6MPa, the temperature at 14.7±2°C, and the concentration ratio of the nanofiltration membrane is 5 times by mass When the nanofiltration membrane separation is stopped. The measured total organic carbon (TOC) of nanofiltration membrane weak liqui...
Embodiment 3
[0037] Get 5kg of by-product salt obtained on the glyphosate production route prepared by glycine method, clean with cleaning agent, control the mass ratio of cleaning agent consumption and solid salt to be 3:1, the cleaning time is 10min, and the number of times of cleaning is 1 time, and then Vacuum filtration was carried out, and the solid salt was obtained after vacuum drying. The solid salt was reconstituted into a solution with a NaCl content of 300g / L. The total organic carbon TOC was measured to be 301.45mg / L, the total nitrogen TN was 53.97mg / L, and the TP was 185mg / L.
[0038] Use 1mol / L NaOH to adjust the pH of the prepared brine to 10, and then perform nanofiltration membrane separation. Control the membrane inlet pressure at 2.6MPa, the temperature at 14.7±2°C, and the concentration factor of the nanofiltration membrane calculated as 5 times by mass Stop the nanofiltration membrane separation. The measured total organic carbon (TOC) of nanofiltration membrane wea...
