preparation example Construction

[0042] The embodiment of the present invention also provides the preparation method of above-mentioned microbial soil remediation agent, comprising:

[0043] Preparation of microbial agent: take 3 to 5 parts by weight of mixed strains of Pseudomonas, Trichoderma, Penicillium, Alcaligenes, Bacillus licheniformis and Bacillus subtilis, and mix the mixed strains with water evenly to obtain microbial Bacteria solution.

[0044] Mix the microbial bacterial agent solution, 20-40 parts by weight of biomass and 60-75 parts by weight of nutrients, ferment at a temperature of 50-60°C for 5-10 days, and then mix with 20-25 parts by weight of montmorillonite powder 13-17 parts by weight of attapulgite, 18-32 parts by weight of diatomite, 13-20 parts by weight of sulfate filler and 5-10 parts by weight of adsorbent are uniformly mixed to obtain a uniform microbial soil restoration agent.

[0045] Based on the above, the preparation method of the microbial soil remediation agent is simple ...

Embodiment 1

[0048] Preparation of microbial inoculum: take 4 parts by weight of mixed strains of Pseudomonas, Trichoderma, Penicillium, Alcaligenes, Bacillus licheniformis and Bacillus subtilis, and mix the mixed strains with water evenly to obtain microbial inoculum solution.

Abstract

The invention provides a microbial soil remediating agent and a preparation method thereof, and relates to the field of soil remediation. The method comprises the following steps: uniformly mixing pseudomonas, trichoderma, penicillium, alcaligenes, bacillus licheniformis and bacillus subtilis to obtain a microbial agent; and uniformly mixing 20-40 parts by weigh of biomass, 60-75 parts by weight of nutritional agent, 3-5 parts by weight of microbial agent, 20-25 parts by weight of montmorillonite powder, 13-17 parts by weight of attapulgite, 18-32 parts by weight of kieselguhr, 13-20 parts byweight of sulfate filling agent, and 5-10 parts by weight of adsorbing agent to obtain the uniform microbial soil remediating agent. The microbial soil remediating agent is capable of remediating soilsubjected to heavy metal pollution, pesticide residue pollution, etc.; and the microbial soil remediating agent has the advantages of being good in treatment effect, and low in treatment cost.

Description

technical field [0001] The invention relates to the field of soil remediation, and in particular to a microbial soil remediation agent and a preparation method thereof. Background technique [0002] The mechanism of microbial soil remediation technology is to use naturally occurring or cultivated functional microorganisms to promote or strengthen the metabolic function of microorganisms under suitable environmental conditions, thereby reducing the activity of toxic pollutants or degrading them into non-toxic substances. That is, under the stress of pollution, microorganisms can secrete certain organic substances from the body that have the ability to complex or decompose and transform pollutants, so that the mobility of pollutants is reduced or the polarity is changed, so that it is not easy to enter the organism; or, Under the action of extracellular enzymes secreted by microorganisms, pollutants are decomposed and transformed into non-toxic and harmless substances in vitro...
