Soil remediation system for in-situ microorganisms

Abstract

The invention discloses a soil remediation system for in-situ microorganisms. The soil remediation system comprises two parallel bar blocks, wherein bar grooves are formed in the side walls of the twobar blocks respectively; the opposite side walls of the bar blocks are rotationally connected with a roller together; a sunshade net is wound on the roller; one end of each bar block is rotationallyconnected with a first transparent barrel respectively; the inner wall of each first transparent barrel is fixedly connected with a telescopic air bag; and each telescopic air bag is filled with an evaporating solution with low boiling point. The first transparent barrels are driven by magnetic force to rotate, the transparent parts of the first transparent barrels and second transparent barrels are overlapped, sunlight can be irradiated into the first transparent barrels, the evaporating solution with low boiling point inside the telescopic air bags is gasified by heat absorption, sliding plugs are pushed to move forwards to the interiors of the bar grooves, and then the sunshade net can be driven to move for spreading, so that the sunshade net can be spread automatically at high noon without manual operation, and the system is simple in structure and low in equipment cost.

Description

technical field [0001] The invention relates to the technical field of soil remediation equipment, in particular to an in-situ microbial soil remediation system. Background technique [0002] In-situ microbial remediation does not need to remove the contaminated soil from the site, but directly puts nutrients such as N and P and oxygen supply into the contaminated soil to promote the metabolic activity of indigenous microorganisms or special functional microorganisms in the soil and degrade pollutants. [0003] However, in situ microbial remediation at noon in hot summer with strong sunlight, the activity of microorganisms will be greatly reduced under the sun exposure, thereby slowing down the degradation rate and prolonging the remediation cycle of contaminated soil. At the same time, under high temperature, nutrients such as N and P are easily Volatile, and microorganisms will die under continuous exposure. [0004] In the existing technology, in order to pursue a shorte...

Problems solved by technology

[0003] However, in situ microbial remediation at noon in hot summer with strong sunlight, the activity of microorganisms will be greatly reduced under the sun exposure, thereby slowing down the degradation rate and prolonging the remediation cycle of contaminated soil. At the same time, under high temperature, nutrients such as N and P are easily Volatile, and microorganisms will die under continuous exposure

[0004] In the existing technology, in order to pursue a shorter repair cycle, it is necessary to artificially cover the sunshade net at noon to block the strong sunlight, and then lift the sunshade net when the temperature is suitable in the afternoon to allow photosynthetic bacteria and other microorganisms that need sunlight to metabolize Degrading pollutants not only consumes manpower, but also the weather is hot at noon, and people exposed to the sun are prone to heatstroke; if intelligent equipment is used for automatic bedding, the cost of equipment will be high, and the installation of automated equipment in pursuit of a shorter repair cycle will not be worth the candle.
