Embodiment 1
[0037] The present embodiment proposes a kind of incineration treatment process of glyphosate mother liquor, comprises the following steps:
[0038] A. Send the glyphosate mother liquor into the membrane treatment device to obtain concentrated mother liquor and permeate. In the concentrated mother liquor, 10% is used for glyphosate powder extraction, and 90% is used to complete the operation of step B;
[0039] B. After the concentrated mother liquor is oxidized once and separated by crystallization, a centrifuge filtrate is obtained, and the centrifuge filtrate is sent to a membrane separation system to obtain a concentrate and a permeate;
[0040]C. The concentrated solution obtained by the membrane separation system is subjected to secondary crystallization and separation, and the centrifugal filtrate is sent to the incineration system to obtain sodium pyrophosphate, and the flue gas generated by incineration is separated from dust and then subjected to secondary combustion....

[0042] The present embodiment proposes a kind of incineration treatment process of glyphosate mother liquor, comprises the following steps:
[0043] A, sending the glyphosate mother liquor into the membrane treatment device to obtain concentrated mother liquor and permeate, in the concentrated mother liquor, 20% is used for glyphosate powder extraction, and 80% is used to complete the operation of step B;
[0044] B. After the concentrated mother liquor is oxidized once and separated by crystallization, a centrifuge filtrate is obtained, and the centrifuge filtrate is sent to a membrane separation system to obtain a concentrate and a permeate;
[0045] C. The concentrated solution obtained by the membrane separation system is subjected to secondary crystallization and separation, and the centrifugal filtrate is sent to the incineration system to obtain sodium pyrophosphate, and the flue gas generated by incineration is separated from dust and then subjected to secondary combust...
Embodiment 3
[0048] The present embodiment proposes a kind of incineration treatment process of glyphosate mother liquor, comprises the following steps:
[0049] A. Send the glyphosate mother liquor into the membrane treatment device to obtain concentrated mother liquor and permeate. In the concentrated mother liquor, 15% is used for glyphosate powder extraction, and 85% is used to complete the operation of step B;
[0050] B. After the concentrated mother liquor is oxidized once and separated by crystallization, a centrifuge filtrate is obtained, and the centrifuge filtrate is sent to a membrane separation system to obtain a concentrate and a permeate;
[0051] C. The concentrated solution obtained by the membrane separation system is subjected to secondary crystallization and separation, and the centrifugal filtrate is sent to the incineration system to obtain sodium pyrophosphate, and the flue gas generated by incineration is separated from dust and then subjected to secondary combustion...
