Properties of Organic Matter in Composts Based on Sewage Sludge
The aim of the research was to assess the quality of organic matter contained in sewage sludge composting products and their co-composting with fly ash and mineral wool. The object of the research were composts produced using stabilized sewage sludge from the municipal sewage treatment plant (SS_1C) and sewage sludge with the addition of 20% (SSF_2C) and 30% (SSF_3C) of fly ash and 5% (SSW_4C) and 10% (SSW_5C) of mineral wool. Selected physicochemical properties, fractional composition of humic compounds, and the degree and rate of humification were determined in compost samples taken after 180 days of composting. The reaction of the evalu - ated composts was close to optimal for mature composts. Co-composting of sewage sludge with mineral wool and ash increased the sorption capacity in composts compared to SS_1C. Due to the content of available P and Mg, the discussed composts formed the SS_1C>SSF_2C and SSF_3C>SSW_4C and SSW_5C series. However, in terms of available K content: SSF_2C and SSF_3C>SSW_4C and SSW_5C>SS_1C. In the SS_1C compost the organic carbon (TOC) content was slightly higher, but no statistically significant effect of the addition of fly ash and mineral wool on the TOC content in mature composts was confirmed. The addition of ash and mineral wool significantly increased the total nitrogen content. Due to the humification index, the composts formed the series: SSW_4C > SSW_5C > SSF_2C > SS_1C > SSF_3C. The values of the C-KH/C-KF ratio in SS_1C were typical for good quality soils, while in the remaining composts the C-KH/C-KF values were slightly lower. The degree of humification of the assessed composts was characterized by poorly humified organic materials, with the highest values of this indicator found in composts with the addition of mineral wool. The assessed quality indicators of organic matter indicate that the organic matter of composts from sewage sludge with the addition of mineral wool and 100% sludge was of the highest quality.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
