摘要

The present invention relates to a granular carrier and a method for producing the same, and to an apparatus for treating sewage or waste water by using the granular carriers. The granular carrier comprises a tire powder of 100 parts by weight, an EVA or its derivative of 30 to 50 parts by weight, and an activated carbon or inorganic micropowder equivalent thereto of 5 to 15 parts by weight. The granular carriers producing method comprises the steps of: mixing a tire powder of 100 parts by weight and an EVA or resin of 30 to 50 parts by weight, resolving the EVA or its derivative of the mixture at a temperature of 100 to 250 C., bonding an activated carbon to the tire powder, extruding the mixture, cutting the mixture extruded, and attaching the activated carbon powder to the EVA or its derivative dissolved on the surface of the cut part of the mixture. The sewage or waste water treatment apparatus is also disclosed.
