Example Embodiment

[0033] Example 1 The soil remediation agent for treating heavy metal pollution is mainly prepared from the following raw materials: 280 kg of organic fertilizer, 28 kg of microbial inoculum, 0.03 kg of matrine, 0.05 kg of pyrethrum, 0.03 kg of fish vine, 0.04 kg of chlorothalonil, thuringiensis Bacillus powder 0.02 kg.

[0034] The preparation steps of the soil remediation agent are as follows:

[0035] (1) Put the organic fertilizer on a sterile plastic film, spread it out, cover it with a sterile plastic film, sterilize it with ultraviolet rays for 2 days, lift off the film, and put it in a cool place to add microbial inoculants and mix well for later use;

[0036] (2) The pyrethrum and the fish vine are dried and ground into powder, passed through a 160-mesh sieve, added with water 200 times the weight of the raw material, and stirred for 20 minutes to obtain a suspension, which is evenly sprayed on the fertilizer obtained in step (1), dry, spare;

[0037] (3) Put matrin...

Abstract

The invention discloses a soil restorative agent for treating heavy metal pollution and a preparation process of the soil restorative agent. The soil restorative agent is mainly prepared by adopting an organic fertilizer, a microbial agent, matrine, pyrethrum, derris, chlorothalonil and agritol powder. The weight percent of each raw material is as follows: 280 to 320 parts of organic fertilizer, 28 to 32 parts of microbial agent, 0.03 to 0.07 part of matrine, 0.05 to 0.1 part of pyrethrum, 0.03 to 0.09 part of derris, 0.04 to 0.08 part of chlorothalonil and 0.02 to 0.06 part of agritol powder. The organic fertilizer is used as a main raw material, the microbial agent for alleviating the harm of soil heavy metal and salt and alkali is added, an insecticidal effect and a sterilizing effect can be simultaneously achieved, the soil restorative agent can further enter the soil, and the soil polluted by the heavy metal can be improved.

Description

technical field [0001] The invention relates to the field of environmental protection and soil pollution treatment, and discloses a soil remediation agent for treating heavy metal pollution and a preparation process thereof. Background technique [0002] Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds, mainly caused by human factors such as mining, waste gas discharge, sewage irrigation and the use of heavy metal products. Heavy metals are not easy to move and dissolve, and cannot be excreted after entering the organism, which will cause chronic poisoning. Heavy metals are widely distributed in the atmosphere, water, soil, and organisms, and sediment is often the storage and final destination of heavy metals. When the environment changes, the form of heavy metals in the sediment will be transformed and released to cause pollution. Heavy metals cannot be biodegraded, but they are bioaccumulative and can directly threaten hig...
