large amount of effluent water would be produced from low temperature coal catalytic gasification (LTCCG) developed by ENN Co, Ltd, which located at Langfang, Hebei Province. Many phenol homologous compounds and a large amount of other organic compounds were contained in this effluent water, but the overall concentration of the organic compounds was not very high (CODCr value was about several thousands mg/L). Too high cost would occur if treating it with a traditional liquid-liquid extraction process, and it was a waste of resources if the effluent water was directly purified with biochemical technology. In this paper, a decontaminating and recycling technique was developed for an effluent water, and a two-step technique includes flocculation-recycling and ion exchange adsorption-elution processes. By this two-step process, the CODCr value of the final outlet water was decreased to meet the related national standards, and at least 90% of the organics in the effluent water could be recovered.
