Method for resource treatment of heavy metal polluted soil on site

The invention relates to the technical field of heavy metal solidification and detoxification, and discloses a method for resource treatment of heavy metal polluted soil on site. A clay body, aluminumoxide, strong acid, sandstone, silver powder, water, a gas tank, a flame spray gun, a cold air blower, a scraper, a kiln, quartz sand, sodium carbonate, nitrate double salt, silicon dioxide and a crusher are used. A formula comprises the following raw materials in percentages by weight: 65%-70% of the clay body, 2%-3.5% of the aluminum oxide, 3%-3.5% of the strong acid, 8%-10% of the sandstone, 0.01%-0.02% of the silver powder, 7%-12% of the water, 0.2%-0.5% of the quartz sand and 0.2%-0.3% of the sodium carbonate. When the method is implemented, the leakage of heavy metals is avoided, the clay body is made into a brick blank, the brick blank made of the clay body is placed into the kiln to be fired, and then the clay is converted into bricks. The silver powder adsorbs heavy metals and the aluminum oxide warps th
