In order to improve the problem of low oxygen supply efficiency during aerobic composting and prolong maturity, a genetic algorithm was used optimize initial weights thresholds standard BP neural network obtain optimal parameters, then clonal selection mutation operator in duplicate operator. A CGA-BP based on an aeration prediction model constructed, predicted by ferment compost accelerate pro...

ACKNOWLEDGMENTS The project was supported with a grant from the New York State Department of Economic Development, Office of Recycling Market Development (ORMD). Additional support was provided by the New York City Department of Sanitation (DOS) and by the New York City institutions and businesses, and compost technology providers described in this report. II Purpose of the Study Composting is ...

Kuhlman, L.R., 1990. Window composting of agricultural and municipal wastes. Eur. Symp. on Integrated Resource Recovery from Municipal Solid Wastes. Resour. Conserv. Recycl., 4: 1 5 1 160. Many wastes are produced from agricultural and municipal facilities that are not suitable for direct land application. Composting these wastes converts them to a humus-containing organic material advantageous...

Waste accumulation is reported to be one of the serious environmental problems. Organic wastes such as organic fraction of municipal solid waste (OFMSW) or sewage sludge (SS) can be treated using aerobic microbial decomposition called composting. It is important to know when composts obtained in co-treatment processes turns to be safe but not toxic for the environment. In this study, we estimat...

alcohol production from molasses can lead to large amounts of wastewater that cause serious environmental concern. it is characterized with extremely high organic loading rate, high turbidity and dark brown color .composting this kind of wastewater is a biothermal aerobic process that during composting heat generated by the composition of the organic material reduces the moisture content of the...

The composting process of pig manure requires separation from the slurry and maturity under aerobic conditions. Thus, we investigated anoxic characteristics correlation between each factor. First, a decanter solid-liquid separator was used, separated transported to laboratory in an impervious bag. We mixed sawdust (bulking agent) 6:4(V/V) ratio adjust moisture content 70%. About 140 liters mate...

Pilot composting experiments of swine manure with corncob were conducted to evaluate the performance of the aerated static bin composting system. Effects of temperature control (60 and 70 degrees C) and moisture content (70% and 80%) were monitored on the composting by measuring physical and chemical indexes. The results showed that (1) the composting system could destroy pathogens, converted n...

Composting is a robust waste treatment technology. Use of finished compost enables plant nutrient recycling, carbon sequestration, soil structure improvement and mineral fertiliser replacement. However, composting also emits greenhouse gases (GHG) such as methane (CH4) and nitrous oxide (N2O) with high global warming potential (GWP). This thesis analysed emissions of CH4 and N2O during composti...

Prickly pear (Rosa roxburghii Tratt), a shrub mainly distributed in South China, is an economically essential plant for helping the local people out of poverty. To efficiently provide sufficient nutrients to soil ecological cultivation prickly pear, we studied aerobic composting litter with three agents, including AC (Bacillus natto, Bacillus sp., Actinomycetes Saccharomyces Trichoderma Azotoba...
