摘要 |
The present invention provides an adsorbent comprising calcined coke with a BET surface area of 20 m2/g or less which is obtained by calcining a particular carbonaceous material at 1000 to 1500° C. and which is preferably obtained by calcining coal coke, petroleum coke or charcoal coke at 1000 to 1500° C. The adsorbent of the present invention exhibits adequate adsorbent ability with respect to an oil component in oil-containing wastewater even when the oil-containing wastewater is an emulsion or contains a low concentration of the oil component, and also stably maintains the adsorbent ability over a long period of time.
