1. , a kind of method of utilizing glyphosate in the high saliferous glyphosate mother solution of membrane technique concentrating and separating, it is characterized in that:

  • this method comprises that mainly step is as follows;

    the glyphosate mother solution that contains a large amount of salt separates;

    earlier mother liquor is carried out pre-treatment, regulate PH between 2~

    11, reach water pollution index SDI≤

    5 and o'"'"'clock enter the one-level membrane sepn, when the glyphosate mass percent reaches 2~

    5% in the dense side mother liquor, be collected in storage tank, the then continuation of glyphosate mass percent below 2% separates in the concentrated solution, and the glyphosate mass percent is collected in storage tank after reaching more than 2% in concentrated solution;

    Rich saliniferous one-level sees through liquid and enters the secondary membrane sepn, and the secondary concentrated solution returns and enters the one-level membrane sepn;

    Rich saliniferous secondary sees through liquid and enters three grades of membrane sepn, and three grades of concentrated solutions return and enter the secondary membrane sepn, and a large amount of salt sees through liquid with three grades and drains.
