The invention discloses a refuse disposal method for producing organic fertilizer by utilizing fast fermentation of biological refuse. The technique aims at realizing complete reutilization of the biological refuse and zero emission in the processing process. The method comprises the following steps: carrying out classification on the biological refuse by utilizing the principle that organic acid can accelerate decomposition of nemaline and inorganic mineral matters, respectively adding acid materials by proportion according to different types of nemaline material and inorganic mineral matter material to carry out refuse mixing pretreatment, and then carrying out biological fermentation; at the final stage of organic fertilizer fermentation, utilizing safe anaerobic bacteria such as highly-activated high-purity nitrogen-fixing bacteria and the like to carry out highly no-nitrogen fermentation, utilizing high-activity functional microorganism and high anaerobic environment to highly restrict and largely kill h
