80mm以下粒径的垃圾堆肥工艺优化研究
Process study of municipal solid waste composting with particle 〈80mm
摘要
Abstract
This paper aims to study the compost maturity influenced by pile-turning and crushing and shortening composting periods,and then analyze the feasibility of these new processes by fuzzy mathematics,based on the existing processing mode of Nangong Compost Plant in Beijing.The experiment was conducted with composting materials 0-80 mm MSW screened out from Majialou transfer station,and designed as three treatments：T1：8 days of high temperature fermentation followed by 12 days of post-ripening fermentation and 12 days of terminal-ripening fermentation,turning and crushing once,32 days in total;T2：7 days of high temperature fermentation followed by 12 days of post-ripening fermentation and 12 days of terminal-ripening fermentation,turning and crushing once,31 days in total;CK：8 days of high temperature fermentation followed by 12 days of post-ripening fermentation and 12 days of terminal-ripening fermentation,no turning or crushing once,32 days in total.The results show that：compared with CK,the evaluation level of T1 is the highest,which means that the technology of pile-turning and crushing can improve the maturity of compost greatly;the maturity of T1 and T2 differs little,indicating the feasibility of shortening composting period under the process of pile-turning and crushing.关键词
