摘要
利用原生生活垃圾,通过三阶段温度控制技术进行堆肥试验,探讨在堆肥过程中有机态氮组分的动态变化规律.结果表明,全氮、酸水解有机态氮、氨基酸态氮均在堆肥的前期呈明显的下降趋势,呈较好的相关性.与CK(对照组)处理相比,在堆肥的后期,三阶段温度控制堆肥酸水解有机态氮、氨基酸态氮、氨基糖态氮及酸解未知态氮含量呈不同程度的上升趋势,增加幅度依次为:10.67%1、6.17%、7.17%、22.44%.表明三阶段温度控制技术能减少堆肥中氮素的损失,堆肥产品施入土壤后,可提高土壤的供氮潜力.
Compost is one of the disposal ways for the municipal solid wastes （MSW）, and the content of nitrogen （N） effects compost quality. Dynamic changes of organic nitrogen were discussed during MSW eomposfing with three stages controlled by temperature （TSCT） technology. At different compost phases, the samples were taken for the determination of the nitrogen forms, and the effect of TSCT technology on nitrogen forms was studied. During MSW eomposting, the acid hydrolysis N, total N and amino acid N are a significant correlation and all decreased at the initial stage of eomposting. While at final stage eomposting, the content of acid hydrolysis N, amino acid N, aminosngar N and unidentified N of TSCT treatment increase by 10.67%, 16.17%, 7.17%, 22.44% compared to CK. The results indicate the eomposting with TSCT technology would reduce the loss of N, improve the quality of MSW compost.
