Problems solved by technology

Generally, it is prepared by mixing fertile field soil and decomposed manure. There are also nutrient soils selected from imported high-quality peat and coconut bran mixed in a specific proportion. However, these nutrient soils have not undergone reasonable ingredients and strict disinfection. Conducive to the normal growth and development of seedlings
[0009] Because the treated nutrient soil is relatively light and loose, the conventional product of nutrient soil is relatively large, which is not conducive to reducing the cost of production and transportation

Embodiment Construction

[0063] Below in conjunction with embodiment the present invention will be further described:

[0064] 1. The production method of compressed nutrient soil from construction waste: (1) Input the ingredients of compressed nutrient soil from construction waste into a running mixer for stirring, and after stirring evenly, input it into a tablet press and compress it into a sheet of compressed nutrient soil from construction waste, and compress nutrient soil from construction waste The thickness of the soil flakes is controlled at 18 mm; (2) The compressed nutrient soil flakes of construction waste are transported to a microwave belt drying and sterilizing machine for low-temperature sterilization and drying. The temperature is controlled at 70-90°C and the time is controlled at 50 Minutes, the water content of the sterilized and dried construction waste compressed nutrient soil flakes is ≤15%; The residual heat in the compressed nutrient soil sheet is continued to be sterilized an...

Abstract

The invention discloses a method for producing construction waste compressed nutrient soil. According to key points of the technical scheme, the method comprises the following steps: acidizing construction wastes and sludge; stirring, compressing and performing microwave low-temperature sterilization on construction waste compressed nutrient soil; packaging to obtain the finished product. The construction waste compressed nutrient soil consists of acidized construction wastes, acidized sludge, instant sodium silicate, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, high-viscosity attapulgite clay, biogas slurry, biogas residues, crushed plant fibers, expanded vermiculite, expanded perlite, super absorbent resins and other materials. The construction waste compressed nutrient soil contains lots of nitrogen, phosphorus, potassium, organic matters and multiple trace elements, can provide nutrient elements essential for plant growth and has the effects of reducing hazard of pathogenic bacteria and injurious insects to plants, promoting normal growth and development of plants and protecting the ecological environment, and the method for producing the construction waste compressed nutrient soil is suitable for producing construction waste compressed nutrient soil of different formulas.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of construction waste compressed nutrient soil. Background technique [0002] Construction waste refers to the waste generated during the construction, laying or demolition and repair of various buildings, structures, pipe networks, etc. by construction units or individuals; the components of construction waste include: scattered mortar and concrete, crushed Packaging of bricks and broken concrete blocks, yellow sand, stones, block stones, muck scattered during transportation, scrap steel bars, scrap iron wires, various scrap steel fittings, metal pipeline scraps, waste bamboo wood, wood chips, shavings, and various decorative materials boxes and bags etc. [0003] At present, construction waste is mainly disposed of by landfill, and the recycling rate is very low. [0004] Sludge is a kind of easily corrupt and smelly paste produced in the process of sewage treatment. It en...
