Abstract

The invention belongs to the technical field of soil improvement and discloses a soil restoration conditioner for heavy metal pollution and a preparation method thereof. The soil restoration conditioner is prepared from, by weight, 20-60% of beer filtered mud, 5-15% of calcium oxide, 5-20% of organic nutrients, 10-30% of soot, and 5-20% of bacillus subtillis R31fungicide. The soil restoration conditioner and the preparation method thereof are simple in technology and low in cost, and the soil restoration conditioner has the functions of adsorbing heavy metal, passivating heavy metal, increasing organic matters and providing organic nutrition.

Description

technical field [0001] The invention relates to a soil restoration conditioner and a preparation method thereof, in particular to a soil restoration conditioner for heavy metal pollution and a preparation method thereof, belonging to the technical field of soil improvement. Background technique [0002] With the continuous acceleration of the industrialization process, the irrational mining of mineral resources and their smelting discharge, long-term sewage irrigation and sludge application to the soil, atmospheric deposition caused by human production activities, and the application of chemical fertilizers and pesticides have caused serious soil pollution. . According to incomplete surveys, there are about 150 million mu of polluted cultivated land nationwide, 32.5 million mu of cultivated land polluted by sewage irrigation, and 2 million mu of land occupied by solid waste stockpiles and destroyed fields, accounting for more than 1 / 10 of the total cultivated land. Most of ...
