Background

The water pollution is the biggest problem existing in the current water environment, particularly, persistent refractory organic pollutants in the water environment are wide in distribution, stable in property and more serious in harm, for example, polycyclic aromatic hydrocarbons can generate secondary pollutants with stronger carcinogenic activity or mutagenicity through a series of complex reactions in the atmosphere or water body, and thus, the secondary pollutants can pose a greater threat to human health. Advanced oxidation technology is an effective way to effectively treat such persistent, refractory organic pollutants.

The hydrodynamic cavitation technology is a new energy utilization method for strengthening the chemical reaction process by utilizing energy released by cavitation. In the process of hydrodynamic cavitation, cavitation bubbles generated by fluid cavitation generate extreme physical conditions of local high temperature (the temperature of a hot spot in the bubble is 4700-5700K, and the temperature of a bubble wall is about 1900K), high pressure (the pressure in the bubble is more than 50 MPa), shock waves, high-speed jet flow and the like when moving and collapsing in liquid, and the extreme conditions are enough to decompose water molecules and open molecular chemical bonds with strong binding force, so that water vapor, dissolved gas and volatile solute vapor in the cavitation bubbles are pyrolyzed, chemical reaction which is difficult to realize under common conditions is realized, and the harmless degradation of organic pollutants which are difficult to degrade conventionally is realized.
