摘要： The invention discloses a method for reducing odor in remediation of pesticide chemical contaminated soil, including the following steps: S101. odor control sustained-release particles are prepared and evenly covered on the surface of the pesticide chemical contaminated soil according to a certain dosage; S102. odor covering base materials and mixed bacterial solution are prepared, and the odor covering soil is prepared by mixing the odor covering base materials and mixed bacterial solution in proportion, and then the odor covering soil is covered on the surface of the pesticide chemical contaminated soil covered by step S101;
S103. heating rods are inserted into the pesticide chemical contaminated soil covered by step S102, and the surface layer of the pesticide chemical contaminated soil is heated to 30˜40° C. The invention can effectively reduce the odor gas in the remediation of the pesticide chemical contaminated soil, and will not pollute the soil twice, and the method for reducing odor is simple and convenient.
