| titleOfInvention | A kind of chemical wastewater treatment method |
| abstract | The invention discloses a kind of chemical wastewater treatment methods, the wastewater from chemical industry contains acrylonitrile, utilize the strong hydroxyl radical free radical OH of the oxidability of ionising radiation generation, promote the acrylonitrile in waste water that polymerisation occurs, the polymerization of Cu2+ and Zn2+ catalysis acrylonitrile is added in waste water, the required absorbed dose of radiation of waste water radiation treatment is reduced, to reduce processing cost；Concrete scheme is in the acrylic nitrile waste water of a concentration of 100mg/L~4000mg/L, add a certain amount of Cu2+ and Zn2+, Cu2+ concentration ranges are 0.8~1.6mg/L, Zn2+ concentration ranges are 0.6~1.0mg/L, radiation treatment is carried out using gamma-rays or high-power electron beam, dosage makes acrylonitrile that irradiation polymerization reaction occur within the scope of 1kGy~5kGy, generate acrylonitrile polymer, the poisonous and harmful substance acrylonitrile being effectively removed by filtering technique in water phase.The present invention uses Cu simultaneously 2+ And Zn 2+ Joint radiation treatment, not only reduces Cu 2+ And Zn 2+ Dosage, reduce secondary pollution, while also significantly reducing irradiation dose, high treating effect, secondary pollution are small, energy saving. |
