Problems solved by technology

[0004] The research on the remediation technology of heavy metal-contaminated soil is the focus of environmental protection engineering science and technology research. The physical and chemical methods commonly used in the remediation methods of heavy metal-contaminated soil have direct and rapid effects, but the persistence is poor. To repair the effect, but will appear new pollution

Embodiment Construction

[0032] The technical solutions of the present invention will be described in detail below in conjunction with the examples and experimental examples, but the scope of protection is not limited thereto. The raw materials used in the present invention can be purchased from the market. For example, the microbial bacterial agent used is the composite microbial bacterial agent produced by Shijiazhuang Fen Bean Fertilizer Technology Co., Ltd.; the microbial bacterial fertilizer produced by Shandong Fengben Biotechnology Co., Ltd. can also be used in the present invention. The matrine used was purchased from Baoji Fangsheng Biological Development Co., Ltd. The Bacillus thuringiensis powder used was purchased from the Pygacacia Bizhi brand Bacillus thuringiensis powder produced by Zhengzhou Huangpu Agricultural Technology Co., Ltd.

[0033] Example 1 The soil remediation agent for heavy metal pollution is mainly prepared from the following raw materials: 280 kg of organic fertilizer...

Abstract

The invention discloses a soil remediation agent for treating heavy metal pollution and a preparation process, which is mainly prepared from organic fertilizer, microbial agent, matrine, pyrethrum, deer vine, chlorothalonil and Bacillus thuringiensis powder, and the mass parts of each raw material 280-320 parts of organic fertilizer, 28-32 parts of microbial agent, 0.03-0.07 parts of matrine, 0.05-0.1 parts of pyrethrum, 0.03-0.09 parts of deervine, 0.04-0.08 parts of chlorothalonil, 0.02 parts of Bacillus thuringiensis powder ‑0.06 parts. The invention uses organic fertilizer as the main raw material, adds a microbial agent capable of reducing soil heavy metal and saline-alkali poisoning, and has both insecticidal and bactericidal effects, can penetrate deep into the soil, and improve heavy metal-polluted soil.

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...
