AI Technical Summary

Problems solved by technology

As a result, although air supply is obtained, key environmental factors such as temperature and humidity are not conducive to the growth and metabolism of microorganisms
In addition, there are problems such as uneven water supply in the process of regulating the water supply of the biopile, which also limits the overall restoration effect of the biopile technology.

Embodiment 1

[0035] Methods to increase the temperature and humidity of the pile body in the biopile restoration technology:

[0036] 1).Using the method of using the generating equipment and the output pipeline together, the heat source and water vapor source generated are transported to the pile through the pipeline, and the valves on the pipeline are all adjusted so that the target temperature of the biological pile can reach 30-40°C , The target humidity can reach 25% to 35%.

[0037] 2). The heat source and water vapor source generated above are provided by the pipeline gas heater and atomizing humidifier of the generating equipment, and the power selection is 2-3m per kilowatt. 3 The earthwork volume is taken as the benchmark, and the material of the conveying pipeline is polyethylene plastic pipe (PE) (caliber 50-70mm).

[0038] 3). According to the size of the restoration test biological pile, the length of the pipeline is selected and the pipeline connection is arranged. The main...

Abstract

The invention relates to the technical field of organic polluted soil microorganism repair, in particular to a method for raising the temperature and humidity of a biopile body in a biopile repair technology. By adopting a temperature and humidity control system, the temperature of the biopile body is raised to 30-40 DEG C and the humidity of the biopile body is maintained at 25-35%(v / m); the temperature and humidity control system consists of generation equipment and a delivery pipeline; the generation equipment is arranged outside the biopile body and is connected with the delivery pipeline; and the delivery pipeline stretches into the biopile body. With the adoption of the method, the temperature of a soil pile body is raised effectively and is maintained within the middle temperature range of 30-40DEG C, and the uniformity of soil temperature field distribution is facilitated; and the soil humidity is maintained within the optimum range of 25-35%(v / m), and the three action effects of soil air supply, heat supply and humidity maintenance are realized.

Description

technical field [0001] The invention relates to the technical field of microbial remediation of organic polluted soil, in particular to a method for increasing the temperature and humidity of a biological pile in the remediation technology of biological piles. Background technique [0002] Microbial remediation technology, as a widely used remediation technology for contaminated soil, has been extensively researched and applied. Its advantages such as environmental friendliness, low price and simple operation have attracted the attention of environmental protection workers. However, the disadvantages of long remediation period and unstable remediation efficiency also limit the application range of microbial remediation technology to a certain extent. With the continuous development of microbial remediation technology in recent years, a variety of microbial remediation technology forms such as soil cultivation, prefabricated beds, bio-slurry reactors and bio-piles have emerg...
