Embodiment Construction

[0015] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0016] A method for preparing a slurry-like fertilizer base material by using organic waste. In the method, firstly, the organic waste is loaded and sieved, and the loading of the organic waste is completed by a remote computer-controlled feeding robot; Garbage containing organic matter is subjected to bag-breaking screening, magnetic separation, and winnowing in sequence. Bag-breaking screening is carried out using a bag-breaking drum screening machine. The diameter of the sieve hole is generally 80mm and 40mm, and the hole diameter can be adjusted. The surface of the plastic bag does not damage hard objects, such as batteries, etc.; the magnetic separation adopts a permanent magnet magnetic separator, and the metals are sorted and collected...

Abstract

The invention relates to a method for preparing a slurry-state fertilizer substrate by using garbage containing organic matters. The method comprises the following steps of: putting the screened garbage containing the organic matters into a flash evaporation blaster, introducing steam to the flash evaporation blaster, controlling the temperature in the flash evaporation blaster to be 210-230 DEG C, the pressure to be 2-3Mpa and the pressure maintaining time to be 80-100 seconds, then finishing flash evaporation blasting within 0.01 second, and preparing the slurry-state fertilizer substrate from the pretreated garbage containing the organic matters. The method is short in acting time, large in blasting power, low in energy consumption, high in efficiency and high in treatment speed, and no harmful gas, such as Dioxin can be generated as the maximum temperature is 230 DEG C. The method disclosed by the invention is convenient for production, strong in operability and environment-friendly, the problems of polluting the environment from garbage and endangering the ecological environment are effectively solved and the cyclic utilization is achieved.

Description

technical field [0001] The invention belongs to the field of making fertilizer from garbage, in particular to a method for preparing a slurry-like fertilizer base material by using organic garbage. Background technique [0002] Fertilizer base material is one of the main materials for preparing fertilizers. According to the organic fertilizer standards and the requirements of different crops for fertilizers, a certain proportion of nutrients can be added to the fertilizer base material to produce various organic fertilizers. At present, organic waste mainly relies on composting, but its composting cycle is long, and impurities and heavy metals cannot be effectively separated. Long-term application of compost products may easily cause impurities and heavy metals to deposit in the soil and pollute groundwater. Moreover, there is an unpleasant smell during the composting process, the organic content of the product is unstable, a large amount of nutrients are released and degrad...
