Study on the Recycled Compositing System for Reducing Bulking Agent Cost
부자재 비용절감을 위한 순환퇴비화 시스템에 관한 연구
Abstract
This study was initiated to investigate the influence of biophysical condition on the composting characteristics, and conducted to develop technology for using recycled compost as a bulking agent cost to reduce operating cost. To methods of aeration, continuous aeration (CA: run No. I) and intermittent aeration (IA: run No. 2) were performed with three 12.3 liter laboratory scale vessels for ten days. Manure and rice hulls were mixed for thirst trial (I), rice hulls and recycled compost after first trial were mixed for second trial (II), dairy manure and only recycled compost after second trial were mixed for third trial (III). During the composting process, temperatures of the compost mass and ammonia emissions were measured. The quality and maturity of compost were ascertained by examining the characteristics and composition of the compost. Also, loss of mass was determined by measuring the mass of materials in the vessels before and after composting. The results in this study are as follows: 1. The periods of optimum temperature (
