Ground sterilizing device and ground sterilizing method

Abstract

Provided is a ground sterilizing device that can efficiently and sufficiently sterilize ground to be treated, and that has superior safety, being able to sterilize ground to be treated without using a chemical agent. The invention is configured provided with: a boiler (2) that generates steam; a superheated steam generation device (3) that generates superheated steam from the steam transferred from the boiler; a superheated steam supply unit (4) that is buried in the ground (X) to be treated during sterilizing processing, and that supplies the superheated steam into the ground (X); and a supply tube unit (5) that supplies the superheated steam generated by the superheated steam generation device (3) to the superheated steam supply unit (4).

Description

technical field [0001] The present invention relates to a soil sterilizing treatment device and a soil sterilizing treatment method suitable for sterilizing the soil where dead animals (cows, chickens, etc.) are buried. [0002] Regarding the scope of this detailed description and patent application, the word "sterilization" does not specifically refer to sterilization (bacteriacicide), but also includes the meaning of killing viruses. Background technique [0003] In recent years, mad cow disease and bird flu have occurred from time to time, and the animal carcasses produced after the culling of these infected cattle, chickens and other animals are generally treated as landfills in prescribed soil. Therefore, from the perspective of safety guards, the soil for burying infected animal carcasses usually needs to be sterilized. [0004] The soil sterilization method widely used in the past is the method of using methyl bromide for sterilization. However, because this methyl ...
