Biochemical Hydrogen Potential Assessment with Anaerobic Batch Biodegradation of Organic Leachate from Aerobic Bio-leaching Bed Feeding Kitchen Waste and Napier Grass

摘要

Napier Grass is an herbage which consists of abundant cellulose. Due to its advantages of easy planting, high-growing rate (it can be reaped every 8 or 10 weeks), high yield density per year (dry matter yield is about 60~80 ton/hectare/year), inexpensive and high electron density (COD/TOC = 3.02 gCOD/gTOC), we decided to choose Napier Grass as one of the substrates in this study. In Napier Grass, nevertheless, considering the abundant cellulose which can lead to the difficulties in hydrolysis, we added kitchen waste as another substrate in order to co-metabolize with Napier Grass. Kitchen waste is a mixture containing different kinds of organic compound such as starch, protein, cellulose, fat and so on.
