In-situ soil remediation device

Abstract

The invention discloses an in-situ soil remediation device, and relates to the technical field of soil remediation. The device comprises a microorganism propagation device for propagating microorganisms, and a connecting insertion plate for connecting the microorganism propagation device with contaminated soil, wherein the microorganism propagation device comprises two culture boxes which are parallel to each other and are arranged at an interval, fixed ends are arranged at two end parts of the two culture boxes, a support column is arranged on the upper surface of each fixed end in a matchedmanner, cross beams are arranged at the end parts of the support columns, and at least two parallel longitudinal beams are arranged between the two cross beams; a channel capable of allowing the connecting insertion plate to penetrate through is formed between the two culture boxes; the bottom ends of the longitudinal beams are connected with a plurality of pneumatic telescopic devices, and the bottom ends of the pneumatic telescopic devices are connected with a sun shield; wherein the connecting inserting plate is of an E-shaped structure. According to the method, in-situ remediation of the contaminated soil is achieved, the soil does not need to be taken out for treatment and backfilling during remediation, the soil remediation cost and labor intensity are reduced, and meanwhile remediation operation is simple.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, in particular to an in-situ soil restoration device. Background technique [0002] With the rapid development of the global economy and society, environmental pollution has become a worldwide problem. Soil pollution is becoming more and more serious as one of the environmental pollution problems. At the same time, the problem of soil pollution in my country has gradually become prominent. The Soil Pollution Prevention and Control Action Plan, known as the "Soil Ten Measures", was issued on May 28, 2016, which fully reflects the country's increasing emphasis on soil pollution. Heavy metal pollution is one of the important types of soil pollution. Heavy metal pollution can not only cause changes in soil composition, structure and function, but also inhibit crop root growth and photosynthesis, resulting in reduced or even extinction of crop yield. More importantly, heavy metals can also ...

Problems solved by technology

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
