| titleOfInvention | Adsorption treatment method for waste water containing octenyl succinate |
| abstract | The invention discloses an adsorption treatment method for waste water containing octenyl succinate, which comprises the following steps: grinding a dried ore material, screening, and reacting with a phosphotungstic acid solution to become ore adsorbent; adding the ore adsorbent into waste water containing 1-20 g/L octenyl succinate, regulating the pH value to 2-5, and oscillating at 5-40 DEG C for 1-12 hours; filtering, adding the ore adsorbent into the filtrate, and oscillating at 5-40 DEG C for 0.5-12 hours; further filtering, and determining that the octenyl succinate removal rate of the filtrate is up to 99% or above and the COD (chemical oxygen demand) value is less than 100 mg/L, so that the filtrate can be circularly utilized or directly discharged; and collecting the filter cakes in the previous two steps, drying, and firing to obtain the regenerated dried ore material. The invention has the advantages that the cheap ore material is prepared into the ore adsorbent, waste water containing octenyl succinate can be efficiently subjected to adsorption treatment by using the ore adsorbent, the ore material can be regenerated and recycled, and the requirements for environment protection and energy saving are met. |
