Problems solved by technology

[0003] In the prior art, the current problems of roof greening mainly include: (1) the range of raw material sources is narrow, the cost of raw materials is high, ordinary soil cannot be used, and only cultivation substrates can be used; (2) the ability to retain fertilizer is poor, and rain is easy to cause Loss of nutrients; (3) Poor moisturizing ability, need to have sufficient buffering ability for water content

Embodiment 1

[0026] Collect meal waste, and use ordinary solid-liquid separation equipment to compress the liquid and solid through axial rotation so that the liquid and solid come out from different openings separately, and the residual oil will gradually decompose in a high-temperature environment. Obtain solid food waste with a solid content ≥ 90%. Mix 60 parts of solid meal waste, 25 parts of fungus residue, 20 parts of livestock and poultry manure and 35 parts of crop straw, adjust the carbon-nitrogen ratio to 40, and add 1.2wt% of high-temperature actinomycetes.

[0027] Carry out high-temperature fermentation: Make the fermentation raw materials into strips, with a bottom width of 2 meters, a height of 1.5 meters, and a strip length of not less than 5 meters. The fermentation temperature is above 75°C and the pile is turned over for the first time, and the pile is turned once every 3-5 days to maintain the pile. The temperature at 30cm below the body surface is not lower than 55°C, ...

Abstract

The invention provides a roof greening substrate, and belongs to the field of food waste recycling. Particularly, food waste is used as a raw material, dry-wet separation is carried out, fermenting iscarried out by using thermoactinomycetes, ageing is carried out, inoculating of nitrogen-fixing bacteria and phosphate-solubilizing and potassium-solubilizing bacteria is carried out, and finally mixing with conventional materials such as peat is carried out, so that the roof greening substrate is obtained. The substrate provided by the invention is viable, is rich in nutrition and has a certaincapability of inhibiting infectious microbes, the nitrogen-fixing bacteria and the phosphate-solubilizing and potassium-solubilizing bacteria can rapidly grow and reproduce, nutrients are provided forplants, and the growth speed of the plants is high.

Description

technical field [0001] The invention relates to a roof greening technology, in particular to a roof greening substrate using food waste as a raw material. The utility model belongs to the field of recycling of leftover meal waste. Background technique [0002] Roof greening technology is becoming more and more common in big cities. (1) Alleviate the urban heat island effect and adjust the urban climate; (2) Roof plants can absorb toxic gases such as sulfur dioxide and nitrogen oxides, retain dust, and purify urban air; (3) Mitigate Urban "dry island effect"; urban "dry island effect" means that the relative humidity of the city is lower than that of the suburbs; roof greening saves precipitation in the matrix or is absorbed by plants, and through the transpiration of plants and the evaporation of soil matrix, the air in the city (4) reduce noise. Roof gardens can reduce noise by 3 decibels and isolate noise by about 8 decibels; (5) increase the area of ​​urban green space ...
