Organic contaminated soil remediation agent and production method and application thereof

Abstract

The invention discloses an organic contaminated soil remediation agent and a production method and application thereof. The organic contaminated soil remediation agent is prepared from the componentsof nano humic acid, micro powder diatomite, mammalian blood powder, compound nutrient powder and a microbial powder agent with the weight ratio of (35 to 45):(10 to 20):(10 to 16):(4 to 6):(1 to 3); the compound nutrient powder is prepared from the components of compound amino acid, compound vitamin, a seaweed extract, hypoxanthine nucleotide and thymine nucleotide; the microbial powder agent is prepared from the components of bacterium powder of bacillus subtilis, sphingomonas, bacillus methanogens, nocardia and arbuscular mycorrhiza and mixed spore powder of pleurotus ostreatus, volvariellavolvacea, lactarius insulsus, morel, boletus, agaricus bisporus and the like. According to the organic contaminated soil remediation agent, soil granular structure can be effectively increased, the soil gap condition is improved, the nutrient content in the soil is improved, the organic pollutant content in the soil is lowered, the microorganism with high degradation ability of the organic pollutant in the soil is supplemented, the growth of plants and microorganisms is improved, and the polluted soil is ecologically and advantageously restored.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to an organic polluted soil remediation agent and its production method and application. Background technique [0002] In the past few years, due to the wanton discharge of industrial waste and excessive use of pesticides and fertilizers, organic pollutants were widely distributed in the environment and enriched in the soil environment, which significantly affected the environmental quality. These pollutants come from a wide variety of sources and generally include volatile organic pollutants such as benzene, toluene, xylene, ethylbenzene, and trichlorethylene, as well as semi-volatile organic pollutants such as polycyclic aromatic hydrocarbons, polychlorinated biphenyls, and organic pesticides. thing. Organic pollutants can directly damage the normal function of the soil, and endanger human health through absorption by plants and accumulation in the food chain...

Problems solved by technology

However, the indigenous microorganisms originally existing in the soil have low ability to degrade these pollutants, so it is necessary to supplement other high-efficiency microorganisms to accelerate the decomposition of pollutants and repair the polluted soil under optimized environmental micro-ecological conditions
