Embodiment 1
[0020] 1) Grind 7g of dry barite and pass it through a 80 mesh sieve, then mix it with 100g of 0.2mol / L phosphotungstic acid solution, shake it for 12 hours, then filter it with suction, wash the filter cake, dry it at 130°C for 2 hours, and pass it through a 80 mesh Sieve to become barite adsorbent;
[0021] 2) Add 5g of barite adsorbent to 1000g of wastewater containing 1g / L octenylsuccinic acid, adjust the pH value to 2, and shake at 5°C for 1 hour;
[0022] 3) After filtering, add 0.5g of barite adsorbent to the filtrate, shake at 40°C for 12 hours;
[0023] 4) Filtrate again, and determine that the removal rate of octenylsuccinic acid in the filtrate reaches 99.97%, and the COD value is less than 100mg / L. The filtrate can be recycled or discharged directly;
[0024] 5) Collect the filter cake obtained by filtering twice in 3) and 4), dry at 110°C for 2 hours, and then burn for 0.5 hour to obtain regenerated dry barite.
Embodiment 2
[0026] 1) Grind 10g of dry natural zeolite and pass it through a 140-mesh sieve, then mix it with 300g of 0.01mol / L phosphotungstic acid solution, shake it for 24 hours, then filter it with suction, wash the filter cake, dry it at 110°C for 4 hours, and pass it through a 80-mesh sieve And become a natural zeolite adsorbent;
[0027] 2) Add 1g of natural zeolite adsorbent to 100g of wastewater containing 20g / L octenylsuccinic acid, adjust the pH to 5, and shake at 40°C for 12 hours;
[0028] 3) After filtering, add 0.5g of natural zeolite adsorbent to the filtrate, shake at 40°C for 11 hours;
[0029] 4) Filtrate again, and determine that the removal rate of octenylsuccinic acid in the filtrate reaches 99.93%, and the COD value is less than 100mg / L. The filtrate can be recycled or discharged directly;
[0030] 5) Collect the filter cake obtained by 3) and 4) two times of filtration, dry at 130°C for 4 hours, and then burn for 1 hour to obtain regenerated dry natural zeolite. ...
Embodiment 3
[0032] 1) Grind 8g of dry kaolin and pass it through a 130-mesh sieve, then mix it with 200g of 0.05mol / L phosphotungstic acid solution, shake it for 20 hours and then filter it with suction. The filter cake is washed, dried at 120°C for 3 hours, and passed through a 100-mesh sieve. Become a kaolin adsorbent;
[0033] 2) Add 2g of kaolin adsorbent to 500g of wastewater containing 10g / L octenylsuccinic acid, adjust the pH to 4, and shake at 30°C for 10 hours;
[0034] 3) After filtering, add 2g of kaolin adsorbent to the filtrate, shake at 5°C for 0.5 hours;
[0035] 4) Filtrate again, and determine that the removal rate of octenylsuccinic acid in the filtrate reaches 99.78%, and the COD value is less than 100mg / L. The filtrate can be recycled or discharged directly;
[0036] 5) Collect the filter cake obtained by filtering twice in 3) and 4), dry at 120°C for 3 hours, and then burn for 1 hour to obtain regenerated dry kaolin.
