Method for Manufacturing Adsorbent using Water Purifying Sludge and Adsorbent Manufactured by This

摘要

The present invention relates to an adsorbent and, more particularly, to a method for preparing an adsorbent by using purification water sludge and an odorous gas absorbent prepared by the same, the method being able to increase chemical activity by mixing an impregnated reagent with the water sludge to disperse flocculation of the purification water sludge flocculated by a polymer coagulant and impregnating the impregnated reagent into a surface and an inner wall of a pore of activated carbon powder or the like included in the purification water sludge; and to enhance adsorption capacity by additionally adding activated carbon. According to the present invention, since the adsorbent is obtained by preparing an adsorbent powder from the purification water sludge that is industrial waste and then by mixing the adsorbent powder with activated carbon, the adsorbent shows significantly high adsorption capacity, excellent strength, and strong acid resistance. In addition, the present invention has an effect of recycling the water sludge that is industrial waste and creates an effect of reducing a discharge amount of waste. Also, according to the present invention, the adsorbent has an effect of replacing expensive activated carbon or zeolite filled in an adsorption tower that is a conventional air pollution control facility. The adsorbent of the present invention also has high strength, good acid resistance, and excellent durability even when prepared in the form of pellet or pill, and thus can be suitably used in the adsorption tower that is the air pollution control facility.
