Abstract

The invention discloses a biological reactor compound bacterium ectopic soil remediation system based on solar strengthening. The soil remediation system comprises a microbial fermentation tank, a nutrient storage tank, a valve, a vacuum pump, a converter, a controller, a solar panel, a heat transfer pipeline, an electrical control panel, a drug injection pipe, a pressure gauge, a suction pipe, anactivated carbon adsorption device and a biological reactor; the microbial fermentation tank is connected to the nutrient storage tank through the drug injection pipe and the pressure gauge, and thesolar panel is connected to the biological reactor through the controller, the converter and the heat transfer pipeline; and an air outlet of the biological reactor is connected to the activated carbon adsorption device through the suction pipe. According to the soil remediation system, through combination of vapor phase extraction and bioremediation technology, volatile organic compounds in soilcan be removed through the vapor phase extraction; organic matters in the soil can be degraded by compound bacteria, and heavy metals in the soil are fixed; and the purpose of remedying the heavy metals and the organic matters in the soil is achieved, and the remediation efficiency of multi-metal contaminated soil is improved.

Description

technical field [0001] The invention relates to the technical field of soil ex-situ remediation, in particular to an ex-situ soil remediation system based on solar energy-enhanced biological pile compound bacterial agent. Background technique [0002] Soil is the natural base for plant growth and reproduction, the basic production resource of agriculture, and an important natural resource on which human beings depend. With the aggravation of industrial and urban pollution and the increase in the types and quantities of agricultural chemicals, soil pollution is becoming more and more serious. Seriously, soil pollution, as a problem that restricts the sustainable development of human society, is attracting more and more attention from all over the world. Soil pollution has the characteristics of long-term and irreversible. The accumulation of harmful substances in the soil to a certain extent will not only lead to soil degradation, crop yield and quality decline, but also poll...
