Problems solved by technology

[0005] However, in the above-mentioned scheme, when the humus soil under the sieve of domestic waste is used as greening soil for resource utilization, the content of heavy metals needs to be considered, and the concentration of heavy metals is controlled by adding other green plant waste or general greening soil. Within the safe range, on the one hand, the application amount of humus is limited, and on the other hand, there are hidden dangers of deterioration of soil properties

Abstract

The invention discloses a bio-organic fertilizer taking humus soil in stock household garbage as a raw material and a preparation method of the bio-organic fertilizer, and belongs to the field of stock garbage resource utilization. The method comprises the following steps: S1, carrying out screening, water washing and dehydration / jigging treatment on stock garbage undersize humus soil to prepare organic matter residues and fuel residues; S2, uniformly mixing the organic matter residues, fly ash and the fuel residues, and controlling the water content to be 20%-30%; adding a dry powder biological agent, uniformly mixing, and granulating to prepare a semi-finished granular organic fertilizer; and S3, continuously spraying percolate pretreated tail water as maintenance water at a certain temperature, maintaining the semi-finished granular organic fertilizer, and performing forced ventilation by using dry hot air during maintenance. According to the method for processing the bio-organic fertilizer by utilizing the humus soil in the stock household garbage, the problem that the content of part of heavy metals exceeds the standard slightly when the humus soil is used as greening soil forresource utilization can be solved, and the large-scale resource utilization of the humus soil in the stock household garbage is promoted.

Description

technical field [0001] The invention belongs to the field of resource utilization of stock garbage, and in particular relates to a bio-organic fertilizer using humus in stock domestic garbage as a raw material and a preparation method thereof. Background technique [0002] Stocked domestic waste refers to domestic waste from informal landfills and substandard sanitary landfills, as well as stale waste from large sanitary landfills. At present, the amount of stocked garbage in my country is as high as 8 billion tons, and it faces problems such as large differences in stability, serious secondary pollution, low resource conversion rate, and urgent land replacement. Utilizing the "urban mining" engineering technology to carry out safe mining, harmless pretreatment, effective resource conversion and recycling of stock domestic waste is the best solution for treating informal landfills and recycling formal landfills. [0003] Stock domestic waste mainly contains the following th...
