Problems solved by technology

With the rapid increase of the urban population, a large amount of feces and urine are produced in daily life. The current treatment method is that the feces and urine are mainly purified by flowing to the sewage plant. Since the excrement and urine are discharged into the septic tank and mixed with other sewage, harmful substances The elements seriously exceed the standard, causing secondary pollution to the environment; moreover, another reason why people are unwilling to use feces is the problem of dirty smell and inconvenient use, resulting in waste of resources

Abstract

The invention discloses a production system of fecal granular fertilizer. The production system comprises a material preparation device, a cooking device, a fermentation device, a granulator and a steam generating device. The material preparation device is used for stirring and mixing raw materials, the cooking device is used for killing insect eggs by high temperature sterilization, the fermentation device is used for fermentation and separation of solid liquid fertilizer, the structure is compact, and the layout is reasonable; the cooking device takes full advantages of wind energy and solarenergy, the energy sources are saved, and the cost is reduced. The invention also discloses a production method of the fecal granular fertilizer. The production method comprises a material preparation process, a cooking process, a fermentation process and a granulation process; after material preparation-cooking-fermentation-granulation, the fecal granular fertilizer is obtained, urban feces notprone to treatment and agriculture straw are converted into liquid organic fertilizer and high-quality fecal granular fertilizer, so that the problem that the feces are dirty, smelly and inconvenientto use is solved, the waste of resources is avoided, and the purpose of turning waste into treasure is achieved.

Description

[0001] Technical field: [0002] The invention relates to a production system and method of granular fertilizer, in particular to a production system and method of manure granular fertilizer. [0003] Background technique: [0004] The macronutrient nitrogen, phosphorus, potassium and trace elements in the soil usually cannot meet the needs of crop growth, and need to be supplemented by the application of chemical fertilizers or organic fertilizers. [0005] Chemical fertilizers are fertilizers made by chemical methods containing one or several nutrient elements needed for the growth of crops. They have the characteristics of high nutrient content, fast fertilizer efficiency, and strong fertilizer. However, chemical fertilizers have no effect of improving soil and fertilizing. Excessive use will cause vicious problems such as soil desertification, salinization, dependence, hormoneization and harmfulness of food and vegetables. [0006] Organic fertilizers are carbon-containing...
