Problems solved by technology

Remediation of contaminated soil by physical methods has the advantage of complete and stable remediation, but the amount of work is large and the cost is high
The chemical method also has the disadvantage of high cost, and the use of chemical agents will destroy the soil structure and cause a decline in soil fertility

Embodiment 1

[0040] Choosing the restoration method of plant mixed planting can not only avoid the disadvantage of incomplete restoration of single plant planting, but also improve the effect of plant restoration. For comparison, see the table below.

[0041] As mentioned above, plants with good remediation effect on the main pollutants are first preferred, and then the selection of plants with different height and function from the first preferred plants is continued. In this way, the above-ground parts of the plants have different layers during mixed planting, which can make good use of the above-ground space, and different plants have different root systems, and the root microbiota formed are also different, which can repair pollution more comprehensively.

[0042] After the land has been prepared and all the ditches and rows have been dug, the selected plants can be planted. The selected plants are planted from east to west, and the selected plants are Crambe abyssinica, Castor bean L...

Embodiment 2

[0047] Plant-microbe joint remediation of pollution can improve the efficiency of remediation. On the one hand, plant roots can provide nutrients for microorganisms, ensure the number and activity of microorganisms, and vigorously growing microorganisms can strengthen the ability of plants to degrade pollutants. The fixation, accumulation and transformation of heavy metals by plants. The restoration results of individual plant mixed planting and plant-microbe joint planting in a certain oil mud field can well explain the problem.

[0048] 2.1) First, as mentioned above, the mixed planting plants were used to remediate the sludge. The mixed planting plants used were Ponnisetum sinese, Castor bean Latin, Crambe abyssinica, arugula ( Eruca sativa Mill) and soybean (Glycine max), the test results after 120 days of planting are shown in Table 2 below.

[0049] 2.2) For the same sludge, use phyto-microbial remediation, as follows:

[0050] 1) Take a small portion of soil from samp...

Abstract

The invention provides a method for rapid remediation of contaminated soil by MP matrix technology. The method utilizes microorganisms and plants to remediate contaminated soil synergistically so as to achieve the purpose of rapid remediation. The method provided by the invention comprises the steps of: 1) conducting sampling and detection on contaminated soil; 2) selecting appropriate plants forplanting according to the detection result and plant properties to remediate the contaminated soil; and 3) selecting microorganisms for inoculation into the soil according to the detection result andmicrobial properties. The method provided by the invention is a fast and green plant-microorganism combined method for remediation of contaminated soil. The method is simple in operation, has strong adaptability and inclusiveness, and has good treatment effect.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a treatment method for joint restoration of soil pollutants by plants and microorganisms. Background technique [0002] Soil pollution refers to the phenomenon that pollutants produced by human activities enter the soil, causing or possibly deteriorating the quality of the soil environment, and causing harm or possible harm to organisms, water bodies, air or / and human health. Soil pollution is mainly reflected in the possible pollution hazards or actual pollution hazards to the receptors, rather than the amount of pollutants. Due to the differences in pollution sources, soils, and receptors in different sites, soil pollution hazards have significant site differences. Compared with other environmental media, the site difference of soil pollution far exceeds that of air or water. [0003] There are many kinds of soil pollutants in my country. According to the "National Sta...
