| description | The invention provides a method for preparing modified nutrient soil from building wastes. The method for preparing the modified nutrient soil by using the construction waste comprises the following steps: (1) crushing the construction waste to 1t; the materials are screened into coarse materials and fine materials through a high-frequency vibrating screen; (2) taking rice straws and banana straws, and respectively crushing to 1t; 5 mm, mixing with the coarse particles in the step (1) and coconut shell activated carbon, and carrying out ball milling for 1.5-2.5 h at the speed of 10-20 rpm; adding the fine material obtained in the step (1), sodium lignin sulfonate and water, and carrying out ball milling at 30-40rpm for 20-40min to obtain a ball-milled material; and (3) drying the material subjected to ball milling in the step (2) at 115-125 DEG C, and crushing to obtain the modified nutrient soil. According to the invention, the construction waste is used as a raw material and is modified by adopting the meth |
