Abstract

The invention discloses a soil remediation treatment agent which is prepared from the following main raw materials in parts by weight: 45-50 parts of a composite adsorbing material, 5-10 parts of a microbial agent, 6-9 parts of saponin, 3-5 parts of polyaluminum chloride and 3-5 parts of polyaluminum sulfate. The soil remediation treatment agent is prepared by the following method: mixing the composite adsorbing material, the microbial agent, saponin, polyaluminum chloride and polyaluminum sulfate evenly according to the weight part proportion, to obtain the soil remediation treatment agent, wherein the composite adsorbing material is prepared by mixing modified bentonite, nano-hydroxyapatite, humic acid, diatomite and lime according to the mass ratio of 3:1:0.3:0.8:0.5 evenly. The soil remediation agent can perform double remediation on soil by absorption action of the composite adsorbing material and degradation action of the microbial agent, is supplemented by remediation of saponins, polyaluminum chloride and polyaluminum sulfate, has remarkable remediation effect on the soil, and has no toxicity or secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to a soil remediation treatment agent. Background technique [0002] According to the "National Soil Pollution Survey Bulletin" published by the Ministry of Environmental Protection and the Ministry of Land and Resources in 2014, the overall environmental situation in the country is not optimistic. Some areas have serious soil pollution, the environmental quality of cultivated land is worrying, and the environmental problems of industrial and mining waste soil are prominent. Man-made activities such as industry, mining, agriculture, and high background values ​​of the soil environment are the main causes of soil pollution or exceeding standards. The total exceeding rate of national soil is 16.1%, of which the proportions of slightly, lightly, moderately and heavily polluted sites are 11.2%, 2.3%, 1.5% and 1.1% respectively. Inorganic pollutants are the main typ...
