미생물을 이용한 가정용 음식물쓰레기 처리에 대한 실험적 고찰 = An Experimental Study on the Treatment of Household Food Waste Using Microorganisms

다국어 초록 (Multilingual Abstract)

The purpose of this study is to investigate the treatment of food waste using microorganisms. The processor used in this experiment employs a PVA carrier which is dominated by microorganisms of the Lactobacillus group. It is equipped with a stirrer to mix food and a water injection device for microbial preservation and proliferation. For the physicochemical analysis, 500 g of food was added to the processor, and the effluent was sampled for 72 hours. The decomposition of organic substance proceeded rapidly until 6 hours - for the period of C / N ratio balance was appropriate. Furthermore, to examine the residual amount and decomposition rate of food, 500g of food was added and were observed for 120 hours. At the end of the experiment, 15 g was retained in the processor, and the decomposition rate resulted in 97%. The remaining 3% food is considered to be non-biodegradable materials. The size of the particles was examined to understand the effects on the sewage pipe by using the effluent of the microorganism extinction processor and the disposer. The size of particles discharged from the disposer were 4.5 times larger in area and 2.4 times larger in length than that of particles from the microorganism extinction processor.
