Problems solved by technology

However, the landfilled garbage has not been completely harmless, and a large number of bacteria and viruses remain, and there are hidden dangers such as methane and heavy metal pollution: garbage seepage will cause secondary pollution, so this method has potential It is more harmful and will bring future troubles to future generations
The garbage incineration method is a traditional garbage disposal method. After the garbage is treated by the incineration method, the garbage can be reduced, the land can be saved, and various pathogens can be eliminated; however, the disadvantages of the incineration method are also obvious, mainly in the following aspects: Its latent pollution is heavier, expensive, complicated to operate and waste of resources.
[0003] In addition, whether it is municipal solid waste or municipal sludge, both contain a large amoun

Example Embodiment

[0027] Example 1:

[0028] A preparation process of a substrate includes the following steps: step one, crushing and sieving municipal domestic waste and agricultural and forestry waste to ensure that the particle size of municipal domestic waste is within 10mm and the particle size of agricultural and forestry waste is within 20mm;

[0029] Step 2: Mix bacteria into the municipal solid waste, agricultural and forestry waste, and municipal solid sludge for independent fermentation. The weight ratio of municipal solid waste, agriculture and forestry waste, and municipal solid sludge to bacterial solid is 2250:1; The municipal solid waste, agricultural and forestry waste and municipal sludge mixed with bacteria are put into a closed fermentation room for fermentation. The fermentation room is equipped with an induced air system and aeration device, and the air flow is continuously introduced into the fermentation room through the induced air system ; Bacterial agents include raw mate...

Abstract

The invention discloses a substrate, and belongs to the field of slope greening. The substrate comprises the following raw materials in parts by weight: 48-62 parts of municipal solid waste, 8-13 parts of forestry and agricultural residues, 16-23 parts of yellow clay and 18-23 parts of municipal domestic sludge. The substrate is prepared by the following steps: firstly, crushing and sieving the municipal solid waste and the forestry and agricultural residues; secondly, adding microbial inoculum to the municipal solid waste, the forestry and agricultural residues and the municipal domestic sludge, and placing the mixture in an airtight fermentation chamber for fermentation; thirdly, performing gradient fermentation on the municipal solid waste, the municipal domestic sludge and the forestryand agricultural residues, wherein temperature of air flow and oxygen content vary with gradient; sixthly, mixing the yellow clay with the fermented municipal solid waste, municipal domestic sludge and forestry and agricultural residues, performing airtight stacking for 10-15 days, and performing sterilization to obtain the substrate. The substrate can be widely applied to slope greening and control of rocky desertification.

Description

technical field [0001] The invention belongs to the field of slope greening, and in particular relates to a substrate, a preparation process thereof and a method for slope greening. Background technique [0002] Municipal solid waste and municipal sludge are the main carriers of urban pollutants, and the current treatment methods for municipal solid waste and municipal sludge are mainly landfill or incineration. Among them, the landfill method is a waste disposal method in which municipal solid waste or municipal sludge is buried underground, and is the oldest waste disposal method. The landfill method is currently the main way of centralized disposal of municipal solid waste and municipal sludge in my country due to its advantages of simple technology and low treatment cost. However, the landfilled garbage has not been completely harmless, and a large number of bacteria and viruses remain, and there are hidden dangers such as methane and heavy metal pollution: garbage seep...
