계분의 퇴비화과정 중 활성탄 첨가에 따른 CO2 및 NH3 저감 연구 = A Study on CO2 and NH3 Reduction during Composting of Chicken Manure by Activated Carbon Addition

다국어 초록 (Multilingual Abstract)

Composting livestock manure emits various air pollutants, including greenhouse gases. Because of the sorptionproperties of activated carbon, the effects of palm shell activated carbon on CO2 and NH3 reduction during compostingof chicken manure were investigated. Tests were performed using chicken manure containing four different activatedcarbon contents: Treatment A, 0wt. %; Treatment B, 5wt. %; Treatment C, 10wt. %; and Treatment D, 15wt. %). Forthese tests, the moisture content was set to 65% in order to minimize the effects of moisture on gaseous emissions. Duringfifty days of composting, the temperature reached a maximum of 55oC for tests B, C, and D at the thermophilic stage.
The total amount of CO2 produced in treatments A, B, C, and D was 4.08 m3, 3.44 m3, 2.54 m3, and 2.08 m3, respectively.
Similarly, the total amount of NH3 produced in tests A, B, C, and D was 0.03 m3, 0.025 m3, 0.020 m3, and 0.018 m3,respectively. For treatments A, B, and C, emissions of CO2 and NH3 decreased as the activated carbon content increased,but treatment D had a relatively limited effect. In addition, the highest microbial activity was observed in treatment C,and the palm shell activated carbon significantly decreased the pathogens in the compost. When factoring in the priceof palm shell activated carbon, using chicken manure containing 10% palm shell activated carbon (treatment C) duringcomposting is recommended in order to reduce CO2 and NH3 emissions.
