چکیده
The objective of this study was to investigate the physicochemical properties and maturity different livestock manures during composting in an opened-static pile system. horse manure (HM), dairy cow (DM), Hanwoo (KM) goat (GM) were used with sawdust as a bulking agent adjust C/N for its relative high carbon content accelerate odor-free process due absorption excess moisture. temperature profile four piles showed increase from earliest days initial temperatures HM, DM, KM GM 46, 61, 45°C, respectively. Comparing moisture fresh composted GM, decreased significantly progressed. volatile solid significant (p < 0.05) but DM similar (21 20.6%, respectively). In addition, ash humic acid (HA) experiment tended progressed, highest HA observed KM. NH4-N all value HM pile. Under same condition composting, species profiles degradability.

Characterization of Odorant Compounds from Mechanical Aerated Pile Composting and Static Aerated Pile Composting.
We studied airborne contaminants (airborne particulates and odorous compounds) emitted from compost facilities in South Korea. There are primarily two different types of composting systems operating in Korean farms, namely mechanical aerated pile composting (MAPC) and aerated static pile composting (SAPC). In this study, we analyzed various particulate matters (PM10, PM7, PM2.5, PM1, and total ...
متن کاملChemical structures and characteristics of animal manures and composts during composting and assessment of maturity indices
Changes in physicochemical characteristics, chemical structures and maturity of swine, cattle and chicken manures and composts during 70-day composting without addition of bulking agents were investigated. Physicochemical characteristics were measured by routine analyses and chemical structures by solid-state 13C NMR and FT-IR. Three manures were of distinct properties. Their changes in physico...

Inelastic Soil-Pile-Structure Interaction under Static Loading
In this paper, inelastic pile-soil-structure interaction under static loading is presented by using finite element and boundary element methods. Linear beam column finite elements are used to model the piles and structural elements. Nonlinear soil is modeled by using nonlinear springs along the piles. Modified Özdemir’s nonlinear model is implemented for springs and systems of equations are cou...
متن کاملPile settlement and volume reduction measurement during forced-aeration static composting.
In this study, a settlement measurement device was used to track the settlement of different layers in composting piles, and time courses of settlement velocity, bulk density distribution, and effective bulk density were investigated. Settlement is divided into two stages: the physical compressive settlement and the mass loss settlement. At the end of the former stage, bulk density (rho') and p...
