生物质炭对城市污泥堆肥过程中碳素转化的影响
Effect of Biomass Carbon on Carbon Transformation During Composting of Urban Sewage Sludge
摘要
Abstract
In order to promote the city land utilization of sludge,the biomass carbon and city sludge were added as the proportion of 0,3%,5% and 10% in city sludge aerobic static composting,composting process of dynamic change under different ratio of moisture content,total organic carbon,humic acid,humic acid,fulvic acid content were studied.The results showed that compared with the control,the addition of biochar could effectively increase the moisture content of compost products and promote the composting process.At the end of each treatment in the compost water content,total organic carbon content decreased,but the water content of treatment 2(5% biomass carbon content,95% rice husk / city sludge(4∶1))increased 5.8 percentage points,the total organic carbon content was higher than the control 40 g·kg-1in each treatment;the end of the period of composting humus carbon content and carbon content of HA increased significantly,the increasing amount from big to small was in turn treatment 2>treatment 3>treatment 1>control.Combined with other indicators and compared with other treatments,when the biomass carbon content was 5%,the microbial activity was promoted in the whole composting process,which can ensure the quality of compost products.关键词
