Embodiment 1

[0043] The inventor collected traditional Chinese medicine residue (moisture content 57%) and urban sewage sludge (water content 60%) from May to June 2021 and mixed them uniformly in a ratio of 5:3 parts by weight to adjust the water content to 60%-65%. .

[0044] Use commercial bacteria 1, commercial bacteria 2, and commercial bacteria 3 to evenly deploy 10kg of powder according to the mass ratio of 1:1:2, activate with 2kg of brown sugar and 15kg of tap water, mix and mix 40kg of wood chips into the pile and mix well, which can be used for a total of 2000kg Material (traditional Chinese medicine residue and urban sewage sludge), add 2000kg of material (traditional Chinese medicine residue and urban sewage sludge), add 25kg of urea to adjust the carbon-nitrogen ratio at 25-35:1.

[0045] On the soil floor of the stacking workshop, build a material stacking pile with a height of 1.5 meters, a length of 5 meters and a width of 3 meters. Turn over every 4 days. After 11 days o...

Embodiment 2

[0047] In July 2021, the inventor carried out an experimental study on the planting safety of green planting soil produced by this method on vegetables and flowers. The measured nutrient content of the green planting soil used for the test is 135mg kg of total nitrogen -1 , total phosphorus 45mg·kg -1 , total potassium 112mg·kg -1 , organic matter 38.1%, moisture 29%. The test varieties were Shanghai green cabbage and cherry radish.

[0048] Pot experiments were used for the cultivation of Chinese cabbage and cherry radish. Three treatments were set up in the experiment: (1) control (CK, using farmland planting soil); (2) greening planting soil produced by this method; (3) commercially available nutrient soil. Pick out stones and other sundry and all adopt 20Kg, put into the seedling pot of diameter 8cm, height 8cm respectively, sow pakchoi or cherry radish seed 5 in every pot. After the seedbed is fully watered, spread it, cover the surface with about 0.5cm of soil and s...

Abstract

The invention discloses a method for preparing green planting soil by using building residue soil, urban domestic sludge and traditional Chinese medicine residues. The method comprises the following steps: microbial inoculum blending: uniformly blending an organic material decomposition agent, an organic fertilizer leavening agent and an organic fertilizer decomposition agent, and mixing to obtain blended microbial inoculum dry powder; activating the microbial inoculum; collecting urban domestic sludge and traditional Chinese medicine residues, uniformly mixing, adjusting the moisture content to 60-65%, selectively adding urea, adding the activated microbial inoculum material, and composting and fermenting to obtain an organic material; and mixing the green planting soil. The invention provides a technology for producing green planting soil, which is simple in process, low in site requirement, short in production period and high in yield and is prepared by composting and then mixing, aiming at the problem that a large amount of three wastes, namely building residue soil, urban domestic sludge and traditional Chinese medicine residues, are generated. The dual purposes of reducing the pollution of the waste to the urban surrounding environment and relieving the urban landscaping pressure after resource utilization are achieved.

Description

technical field [0001] The invention relates to the field of resource recycling of production waste Chinese medicine dregs and waterworks domestic sludge in the production line of pharmaceutical products, in particular to a method for making greening planting soil by using construction dregs, urban domestic sludge and traditional Chinese medicine dregs. Background technique [0002] With the increasing scale of domestic cities, the rapid development of industries and the increasing pollution of the waters around the cities, urban domestic sewage has formed a huge amount of domestic sludge after being treated by sewage treatment plants. At present, the total amount of sewage treatment in my country is about 200 million tons / day, and the amount of wet sludge generated is about 200,000 tons / day. However, among the large amount of sludge produced in our country every year, about 30 million tons of sludge have not been properly settled. The proper treatment of domestic sludge to...
