AI Technical Summary
Technical Problem
Existing water treatment devices face challenges in adjusting bubble size and energy state of plasma due to fixed opening diameters, leading to reduced treatment efficiency for persistent organic fluorine compounds like PFOS and PFOA.
Method used
A plasma micro-bubble generator with adjustable gap and insulating electrodes generates plasma within microbubbles by applying voltage between metal electrodes, allowing for efficient decomposition of organic compounds.
Benefits of technology
The generator efficiently decomposes persistent organic matter in water by generating high-energy plasma within microbubbles, enhancing treatment efficiency and adaptability to varying gas flow rates and bubble sizes.

Abstract
To provide a water treatment device and a water treatment method, simple in structure and easy to operate for purifying contaminated water or the like with a hardly decomposable organic substance such as an organic fluorine compound being mixed therein.SOLUTION: A water treatment device 1 is constituted of a treatment tank 10, a plasma fine bubble generator 20, and a high-voltage power source 30, applies a high voltage from the high-voltage power source 30 to a fluid F including fine bubbles FB flowing out of the plasma fine bubble generator 20 to generate discharge plasma inside the fine bubbles FB, and mixes the discharge plasma with water WD to be treated stored in the treatment tank 10 to perform decomposition treatment of a hardly decomposable organic substance present in the water WD to be treated.SELECTED DRAWING: Figure 1
