Six municipal solid waste (MSW) and yard waste components (food waste, mixed paper, yard waste, leaves, branches, grass clippings) were aerobically decomposed to measure the extent of decomposition under near optimal conditions. Decomposition was characterized by at least two principal stages, for most components, as was indicated by the carbon dioxide production rates. An aerobic biodegradation conceptual model is presented here based on the principle that solids hydrolysis is the rate-limiting step during solid waste composting. The mineralizable solid carbon of each solid waste component was assumed to comprise the readily, the moderately and the slowly (or refractory) hydrolysable carbons, each hydrolyzing at different rates to aqueous (water soluble) carbon. Aqueous carbon mineralizes to CO2 at rapid rates that are not rate-limiting to the process. Solids hydrolysis rate constants were calculated after fitting the experimentally determined carbon dioxide production rate data to model results. Hydrolysis rates for the readily hydrolysable carbon in all components ranged from approximately 0.06 to 0.1 d(-1); hydrolysis rates for the moderately hydrolysable carbon ranged from 0.005 to 0.06 d(-1). Leaves, branches and grass clippings did not have a readily hydrolysable carbon fraction, whilst the leaves and branches had the largest slowly hydrolysable carbon fractions (70%, 82%, respectively, of the total solid organic carbon). Grass and yard waste did not contain slowly hydrolysable carbon fractions. Food waste had the largest readily hydrolysable carbon fraction and produced the highest amount of CO2 among all substrates. Moderately hydrolysable solid carbon fractions ranged from 16% to 90% of the total solid organic carbon for all substrates used. 相似文献

Field research was carried out to assess the effects of the application of reclaimed municipal wastewater on rice cultivation
in Thessaloniki, Greece during a 2-year period (1999–2000). Effects on production cost, soil composition, and health risk
were examined. A randomized complete block design was used for the paddy field with three treatments and four replicates.
The treatments were (1) river irrigation water with N–P fertilization, (2) reclaimed wastewater irrigation with surface N
fertilization, and (3) reclaimed wastewater irrigation without fertilization. The results showed that the total production
cost decreased 8.8% and 11.9% by applying the second and third treatments, respectively, compared to the first treatment,
without significant differences in the agronomic and rice quality traits. Soil composition showed discrepancies between the
2 years and the three treatments, whereas the pathogens of the reclaimed wastewater and rice tissues posed a low human risk
when taking the needed precautions. 相似文献
