[0028] Example 1:
[0029] A treatment method of calcium-containing organic phosphorus scale inhibitor wastewater includes the following steps:
[0030] 1) Pretreatment with commercially available general-purpose macroporous resin D201: Rinse the purchased macroporous resin D201 with clear water until it is clear without turbidity and impurities. Then use 4% NaOH and HCI to soak alternately for 2 hours, rinse with a large amount of water between alkali and acid until it is close to neutral, repeat twice, each time the ratio of acid-base dosage to resin volume is 2:1, then 55 Dry at ℃, pass through a 60-mesh sieve, and set aside;
[0031] 2) Prepare 200mL FeCl 4 - The precursor solution, the molar concentration of ferric chloride hexahydrate is 0.3mol / L, the molar concentration of sodium chloride is 0.2mol / L, and the molar concentration of hydrochloric acid is 0.2mol / L; add 1.2gD201 to the above FeCl 4 - In the precursor solution, the reaction was carried out in an ice bath and ultra...

[0034] Example 2:
[0035] A treatment method of calcium-containing organic phosphorus scale inhibitor wastewater includes the following steps:
[0036] 1) Pretreatment with commercially available general-purpose macroporous resin D201: Rinse the purchased macroporous resin D201 with clear water until it is clear without turbidity and impurities. Then use 5% NaOH and HCI to soak alternately for 4 hours, rinse with a large amount of water between alkali and acid until it is close to neutral, repeat 3 times, each time the ratio of acid-base dosage to resin volume is 3:1, then 55 Dry at ℃, pass through a 60-mesh sieve, and set aside;
[0037] 2) Prepare 200mL FeCl 4 - The precursor solution, the molar concentration of ferric chloride hexahydrate is 1.5 mol / L, the molar concentration of sodium chloride is 0.4 mol / L, and the molar concentration of hydrochloric acid is 0.8 mol / L; 1gD201 is added to the above FeCl 4 - In the precursor solution, the reaction was carried out in an ice bath a...

[0040] Example 3:
[0041] A treatment method of calcium-containing organic phosphorus scale inhibitor wastewater includes the following steps:
[0042] 1) Pretreatment with commercially available general-purpose macroporous resin D201: Rinse the purchased macroporous resin D201 with clear water until it is clear without turbidity and impurities. Then use 5% NaOH and HCI to soak alternately for 2h, rinse with a large amount of water between alkali and acid until it is close to neutral, repeat twice, each time the ratio of acid-base dosage to resin volume is 2:1, then 60 Dry at ℃, pass through a 60-mesh sieve, and set aside.
[0043] 2) Prepare 200mL FeCl 4 - Precursor solution, the molar concentration of ferric chloride hexahydrate in the solution is 1.0 mol / L, the molar concentration of sodium chloride is 0.4 mol / L, and the molar concentration of hydrochloric acid is 0.4 mol / L; 1.5gD201 is added to the above FeCl 4 - In the precursor solution, after 4 hours of ice bath and ultrason...
