초록

Environmental treatment residues become valuable waste byproducts like biomass when an environmental infrastructure necessary for recycling is effectively developed. In this study, an environmentally friendly sewage sludge sorbent was developed in a sewage treatment plant by carefully processing the sewage sludge generated from sewage treatment plants. In order to increase the adsorption efficiency, coffee ground waste was added to the adsorbent as an additive and the adsorbate used in the adsorption experiments was acetaldehyde as organic waste. It could be found from the experiment that the adsorbent of the sewage sludge was adsorbed more easily at the carbonization temperature of 600℃. In addition, adsorption experiments showed that the breakthrough time reached to 85, 110, and 130 minutes at 3:1, 2:2, and 1:3, respectively, depending on the content ratio of the sewage sludge and coffee waste. Therefore, the amount of acetaldehyde adsorption increased with the increase in the amount of coffee grounds in the mixture. It could be also be found that the addition of the coffee grounds as an additive to increase the adsorption capacity of the sewage sludge adsorbent is advantageous for adsorption.
