Abstract:

Caffeine wastewater has been treated by combined process extraction -Fenton -NaClO oxidation. The results show that under experimental conditions，the technology achieves good treatment results，meeting the requirements of terminal treatment. The COD of effluent is about 3 000 mg/L，and the chrome removing rate reaches 93%. The extracting agent can be recovered with NaOH solution through removing efficiency with good effect.

Key words: caffeine wastewater, extraction, Fenton oxidation
