Abstract
Composting is a process that allows the elimination of pathogenic microorganisms, and includes biological sludge stabilization in aerated heaps or in sealed chambers with the addition of supplementary substances. An organic substance that is converted into compost is a good product for soil improvement and land reclamation. Compost is a good organic fertilizer used as manure in rural agglomerations. Organic matter included in the compost affecst the properties of the soil, improves the relationship between water and air, as well as soil rich in nutrients. Compost has the additional properties for improving the structure of light and heavy soils. The temperature of the resulting compost pile can reach up to 70°C. Hight temperature affects the removal of pathogenic microorganisms. In wastewater treatment plants, where the processing of sludge includes dewatering process and fermentation composting can be used as the final sludge processing operation, which is a valuable material intended to be used in nature (assuming that it meets the requirement pertaiting to heavy metal content). Treatment processes significantly influences the type of emitted odorant. During the anareobic process different and more intense odors are produced than under aerobic conditions. Odors are often emitted furing the biological treatment processes. They may be released during storage and transportation of raw materials, during the compost and- in each phase of the composting process.
