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. |
