The spent mushroom compost(SMC) has been generally used as substrate for passive treatment systems, especially for SAPS in Korea. More effective substitutes to replace the SMC have always been a major concern in this area. In this study, rice wine waste(RWW) was tested as substrates for use in acid mine drainage treatment. Batch tests were conducted to evaluate the material’s efficiency in reducing sulfates and removing heavy metals within the artificial AMD. Test results showed that both SMC and RWW have similar efficiency in total sulfate reduction capacity. However, the RWW has a little higher reducing rate, and the mixture of SMC and RWW showed the highest reducing rate. In terms of the heavy metal removal, including Fe, Al, and Cu, both materials showed similar results. Overall, the batch test results indicated that RWW has a good potential as a substrate for SAPS.
국내 자연정화 시설, 특히 알카리생성조는 주로 버섯퇴비를 기질물질로 사용하고 있으나 이를 대체할 수 있는 기질물질의 확보가 필요한 실정이다. 본 연구에서는 산성광산배수 처리를 위한 기질물질로서 막걸리 슬러지의 가능성을 평가하였다. 27일간의 batch test를 통해 버섯퇴비와 막걸리 슬러지의 정화 효율, 즉 황산염 및 중금속의 제거효과를 비교하였다. 두 기질물질 모두 총 제거된 황산염의 양은 비슷했으나, 황산염 환원 속도는 막걸리 슬러지가 조금 더 높은 것으로 나타났다. 또한 두 물질을 혼합한 경우, 총 환원량과 환원속도에서 가장 좋은 효과를 나타냈다. 두 기질물질 모두 높은 Fe, Al Cu의 제거 효율을 보였다. Batch test 결과를 종합해 볼 때, 막걸리 슬러지가 알카리생성조의 기질물질로서의 활용 가능성이 확인하였다.
