Abstract: Curing agent screening test was conducted before restoration work of a battery factory. Nine kinds of agents (lime, cement, sodium dihydrogen phosphate, ammonium dihydrogen phosphate, monocalcium phosphate, calcium hydrophosphate, tricalcium phosphate, phosphoric acid, phosphate fertilizer) were used in the lead polluted soil stabilization experiment. In the stability test, different agents were added to lead contaminated soil respectively. For the soil with low level lead, 10% lime, 20% lime, 10% cement, 20% cement, 10% monocalcium phosphate, 10% tricalcium phosphate, 20% tricalcium phosphate, 10% ammonium dihydrogen phosphate, 20% ammonium dihydrogen phosphate and 20% phosphoric acid could achieve the repair target. For the soil with high level lead, 20% cement, 20% calcium hydrophosphate, 10% tricalcium phosphate, 20% tricalcium phosphate, 10% ammonium dihydrogen phosphate, 20% ammonium dihydrogen phosphate, 10% phosphoric acid and 20% phosphoric acid could achieve the repair target. In view of the cost, cement was chosen as the stabilizer in this project, and the appropriate application amount of cement was 10% for low level lead soil and 20% for high level lead soil.
