The application relates to the technical field of wastewater treatment, and particularly discloses a fracturing flowback fluid treatment process. Sodium hypochlorite is used as an oxidant, and a synergistic catalyst containing nickel oxide and iron oxide is selected to synergize the oxidant, compared with potassium permanganate gel breaker, the sodium hypochlorite not only has better gel breaking effect, but also avoids the introduction of manganese ions, and can fully exert the advantage that the sodium hypochlorite has little influence on chroma. After gel breaking treatment, the viscosity of the fracturing flowback fluid is obviously reduced, which is beneficial to the uniform dispersion of various additives, and therefore the treatment effect on the fracturing flowback fluid is improved.

This application relates to the field of atomization technology, providing an aerosol generating device and an electronic atomizer, including an atomizing component, a housing, a nozzle assembly, and a cap structure. The atomizing component has a liquid inlet. The housing is fitted over the atomizing component and has a liquid storage chamber and a first limiting part. The nozzle assembly is fitted between the atomizing component and the housing. The nozzle assembly is movable along a first direction to switch from an initial state to an active state. In the initial state, the nozzle assembly isolates the liquid inlet and the liquid storage chamber; in the active state, the nozzle assembly connects the liquid inlet and the liquid storage chamber. The first limiting part limits the travel of the nozzle assembly along the first direction. The cap structure covers the nozzle assembly. Under external force, the cap structure drives the nozzle assembly to move along the first direction and also detaches from the nozzle assembly along the first direction when the nozzle assembly is in the active state. Thus, the aerosol generating device can be used simply by applying external force to the cap structure, improving ease of use.
