Soil restorative agent for treating heavy metal pollution and preparation process of soil restorative agent

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...

Embodiment 1

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

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

[0035] (1) Put the organic fertilizer on a sterile plastic film, spread it flat, cover it with a sterile plastic film, sterilize it with ultraviolet light for 2 days, remove the film, put it in a cool place, add microbial agents and mix well for later use;

[0036] (2) Grind pyrethrum and deervine after drying, pass through a 160-mesh sieve, add water 200 times the weight of the raw materials and stir for 20 minutes to prepare a suspension, and spray it evenly on the fertilizer obtained in step (1), dry in the shade, spare;
