摘　　要：文章通过分析我国用混和收集城市生活垃圾生产农用堆肥的现状，指出存在三方面的问题。首先是现行的分选技术不能将垃圾中的有机质与其他杂质成分完全分开．从而导致堆肥成品中杂质含量高；其次是经预处理、发酵和后分选处理的堆肥成品量少，有机质含景低，堆肥成品质量较差，不适宜作为有机肥料；再次。由于原料中所含有的生物质成分复杂，导致成品腐熟程度不均。由此得出．我国混合垃圾堆肥成品作为农用肥料由于其质量问题导致无销路，许多堆肥厂无法运行。This paper analyses the status of agricultural compost, which is produced by municipal solid waste （MSW） of Mix-Collection. There are three problems. The first is that the existing sorting should not completely separate organic matter and other impurities from MSW, resulting in finished compost with high impurity content; The second is that the amount of the finished compost is less after pre-treatment, composting and post sorting, the content of the organic matter is low, the finished compost is poor quality, so that is not fit for as an organic fertilizer; The third is that the product maturity is the degree of inequality in order to the complex components of the biomass from MSW. Therefore, the compost from Mix-Collection MSW as the agricultural compost is non-marketable because of their quality problems, so that causes many composting plant can not run.
