| titleOfInvention | The method that acid heavy metal contaminated soil is repaired using composite modifying agent |
| abstract | The method that acid heavy metal contaminated soil is repaired using composite modifying agent, is related to a kind of method of repairing polluted soil, methods described to include procedure below：1）The acid soil of leaded zinc is air-dried broken；2) soil after crushing is taken, the calcium oxide that particle diameter is 0.1 0.5cm is added；3) to the calcium magnesium phosphate that 2 10% are added in above-mentioned soil；Soil aging 30 ~ 45 days at room temperature after treatment, upset is stirred once week about, and supplements moisture content, and it is the 50 ~ 60% of field capacity to keep moisture content；4) to it is above-mentioned it is aging after soil in add 5 10% sludge fermentation fertilizers be soil after being improved.The method while repairing heavy metal pollution, improves the property and fertility of soil by the heavy metal lead zinc in the reparation and burin-in process soil of chemical improvement agent, it is ensured that the soil after reparation can be used for normal agriculture and forestry production. |
