Abstract

The invention discloses a method and a device for preparing an organic fertilizer by utilizing fecal sewage in an urban septic tank, belonging to the technical field of preparation of organic fertilizers. According to the technical key points, the method comprises the following steps: (1) collecting faeces, feces and sewage; (2) conveying and discharging the liquid dung mixture consisting of the faeces, feces and sewage into a faeces storage tank, adding quicklime powder, and stirring, so that the liquid dung mixture is subjected to solid-liquid separation; (3) standing, and discharging the intermediate dung sewage into a liquid pool for later use by virtue of a pipeline; (4) adding crop straw powder and the residual faeces and feces after the intermediate dung sewage is completely discharged, stirring and forming a semi-finished product; and (5) conveying the semi-finished product into a fermentation tank for fermenting for 15-25 days, packaging after the fermentation is ended, thereby obtaining the powdered organic fertilizer. The invention aims at providing a method and a device for preparing the organic fertilizer by utilizing the fecal sewage in the urban septic tank. According to the method and the device, the operation is easy and convenient, the urban dung sewage can be effectively treated, and the aim of changing wastes into valuable materials is achieved. The method and the device are used for manufacturing organic fertilizers.

Description

technical field [0001] The present invention relates to a kind of preparation method of organic fertilizer, more specifically, relate to a kind of method that utilizes fecal sewage in city septic tank to prepare organic fertilizer. The present invention also relates to a device for preparing organic fertilizer by adopting the method. Background technique [0002] As we all know, human manure is the cheapest, most effective, and healthiest organic fertilizer that has been continuously used in the farming history of the Chinese nation. With the progress of society and the development of rural areas to urbanization, farmland is becoming less and less, and the amount of human manure used is also decreasing. However, the population is increasing, and the amount of feces is also increasing. The feces in urban septic tanks cannot be processed in time. The quality of domestic water, fecal water in urban septic tanks has become a growing environmental problem Contents of the inve...
