Embodiment 1
[0027] A production technology utilizing industrial solid waste to process a multifunctional soil conditioner, the technology comprises the following steps,
[0028] 1) Pretreatment of blast furnace slag solid waste
[0029] Firstly, the solid waste of blast furnace slag is preliminarily screened with 30 meshes, and then roasted at a temperature of 1000°C for 5 hours to effectively remove crystal water and organic impurities;
[0030] After the roasting is completed and cooled, pulverize and grind, and then perform 100-mesh sieving again;
[0031] 2) Surface modification of blast furnace slag solid waste
[0032] The blast furnace slag solid waste pretreated in step 1) is mixed with a composite modifier (silane coupling agent), and the addition ratio of the composite modifier accounts for 5%;
[0033] 3) Premix
[0034] Mixing of functional compositions: mixing the blast furnace slag solid waste modified in step 2) with polymer water retaining agent, borax, zinc sulfate and...
