Method for reusing garden wastes

Abstract

The invention belongs to the field of gardens, and concretely discloses a method for reusing garden wastes. The method comprises the following steps: 1, carrying out fixed point collection; 2, crushing: crushing the collected garden landscaping wastes through a crusher to form crushed wastes; 2, processing: adding a nutrient solution accounting for 10-25% of the volume of the crushed wastes to the crushed wastes to prepare a fermentation substrate, and carrying out moist heat sterilization at 121 DEG C for 20 min; 4, carrying out solid-liquid separation: conveying the sterilized fermentation substrate to a strong squeeze drying machine, and squeezing the sterilized substrate to remove water in order to obtain a concentrate liquid and a solid with the water content of 25%; 5, carrying out softening treatment: spraying molds to the fermentation substrate according to a volume ratio of 10:1, and naturally fermenting the fermentation substrate at 60-65 DEG C for 48 h to obtain a softened material; 6, carrying out irradiation treatment: carrying out ultrasonic irradiation for 30 min after fermentation culture of the culture solution sprayed fermentation substrate to obtain a fermentation product; and 7, decomposing the fermentation product, and sterilizing the decomposed fermentation product to obtain a finished organic fertilizer. The method reuses the garden wastes.

Description

technical field [0001] The invention belongs to the field of gardens, in particular to a method for reusing garden wastes. Background technique [0002] With the continuous advancement of my country's landscaping process, the landscaping area continues to increase. While people are creating more green ecological environments, they have brought a sharp increase in green waste. More and more landscaping garbage, due to the lack of reasonable recycling, not only increases the heavy garbage disposal cost to the landscaping part, but also disposes of it together with domestic garbage, which not only wastes land resources, but also produces serious damages. Exhaust gas pollution, landscaping is to beautify our living environment, and green waste is polluting our living environment. If there is no reasonable way to deal with green waste, landscaping obviously violates the original intention of improving the environment. Studies have shown that the main component of landscaping was...

Problems solved by technology

It is very difficult to decompose under natural conditions, and the natural decay process of its crushed materials often lasts for more than 2 years, resulting in problems such as long processing cycle, environmental pollution, and large floor area. Traditional landscaping waste treatment mainly uses incineration and landfill Incineration will produce lipophilic solid compounds that are difficult to degrade, which is extremely harmful to human health, and landfill will pollute groundwater resources, and its transportation costs are high and cause air pollution
