Abstract

The invention discloses a household waste classifying layer-by-layer fermentation equipment and a fermentation method thereof. The equipment comprises a classification assembly and two anaerobic digestion fermentation pools or above, wherein each anaerobic digestion fermentation pool is provided with a feed port and a scum outlet, the classification assembly is connected with a feed pipe, the feedpipe is connected to the feed port; the bottom of each anaerobic digestion fermentation pool is provided with a discharge pipe; and two fermentation layers or above are arranged in each anaerobic digestion fermentation pool. According to the method, classifying fermentation is combined with layer-by-layer fermentation, the reclamation of waste water is combined, so that the degradation and fermentation of organic matters are effectively promoted, and it is achieved that wastes change into resources.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a sorting layer-by-layer fermentation equipment and a fermentation method for domestic garbage. Background technique [0002] With the growth of urban population and the continuous improvement of residents' living standards, urban domestic waste has grown rapidly, and the content of organic matter in urban domestic waste has increased year by year, of which biodegradable substances are as high as 70%. Therefore, it is of great significance to establish a conservation-oriented society by reasonably disposing of organic matter in domestic waste. [0003] Due to the complex composition of domestic waste, it is relatively difficult to directly degrade biologically, and the cost of anaerobic digestion treatment is relatively high. At present, few of its anaerobic fermentation biogas projects are officially in operation. In reality, domestic waste is mostly dispo...
