Embodiment 1

[0058] Example 1: Soil ecological restoration in a chemical industry zone in Daya Bay Economic Development Zone, Huizhou City, Guangdong Province

[0059] There are many petrochemical enterprises in a chemical industry zone in Daya Bay Economic Development Zone, including more than 30 oil refineries, chemical fiber factories, and chemical factories. The waste generated by them is complex, and some enterprises discharge it without complete treatment. pollution of the soil in the area. In particular, some industrial wastewater seeps into the soil, resulting in a high degree of soil pollution, dark soil and odor. After testing, the soil pollution indicators are as follows: the content of benzo[α]pyrene is 145.21mg / kg, the content of acrylonitrile is 122.48mg / kg, the content of copper is 115.60mg / kg, the content of lead is 109.74mg / kg and the content of cadmium is 2.56mg / kg .

Abstract

The invention provides an ecological restoration method for soil in a chemical industrial area. The ecological restoration method includes the following steps that pollution indexes of the soil in the chemical industrial area are detected; deep ploughing is conducted, clay not smaller than 30 cm under the ground surface is turned up, and the soil is loosened and watered to be wet; a compound microorganism bacterium agent is thrown into the soil with the dosage ranging from 30 ppm/m<2> to 50 ppm/m<2>; terrestrial invertebrates are thrown into the soil; plants are planted on the soil; the pollution indexes of the soil in the chemical industrial area are detected; and the above steps are repeated every other 30 days to 60 days till the quality of the soil meets the requirements. By means of the ecological restoration method for the soil in the chemical industrial area, biological diversity of the soil is restored, the quality of the soil is improved fundamentally, the self-purification capability of the soil is restored fundamentally, and the pollution phenomenon is effectively eliminated. The method is used for strengthening the self-restoring capability and the self-cleaning capability of the nature, and meanwhile the ecological restoration method has the beneficial effects that the running cost is low, and the pollution treatment effect is good.

Description

technical field [0001] The invention relates to an ecological restoration method applied in the field of environmental protection, in particular to an ecological restoration method for soil in a chemical industry area. Background technique [0002] With the accelerated development of our country's economy, human beings have more and more demand for chemical products, and chemical factories are also opened in large numbers in chemical industrial zones all over the country. While bringing economic benefits, chemical plants produce a large amount of pollutants. Some pollutants, such as heavy metals cadmium, lead, acrylonitrile, and bicyclic and tricyclic polycyclic aromatic hydrocarbons, are directly discharged without treatment. These pollutants penetrate into the In the soil, it kills the microorganisms in the soil, changes the composition of the soil, and changes the ecology of the surface, causing serious soil pollution in the area around the chemical plant, and even the po...
