Problems solved by technology
The disadvantage is that the power consumption and electrode metal consumption are large when dealing with a large amount of wastewater, and the separated sediment is not easy to process and utilize.
At the same time, it will also produce metal cation interference in the solution, which is not suitable for water quality detection

Embodiment Construction
[0022] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0023] like figure 1 As shown: the present invention includes an inlet pump 2, an inlet valve 3, a flow meter 4, an ultrasonic atomizer 5, a high-voltage corona reaction chamber 6, a circulating pump 7, an outlet pump 8 and an outlet valve 9.
[0024] like figure 1 As shown: the inlet pump 2 is used to extract the wastewater sample 1, and the wastewater sample 1 extracted by the inlet pump 2 enters the ultrasonic atomizer 5 through the inlet valve 3 and the flow meter 4. The waste water sample 1 entering the ultrasonic nebulizer 5, under the action of cavitation and excitation of 1.6MHz-2.5MHz ultrasonic waves, the molecular kinetic energy increases and becomes mist, and the waste water sample 1 absorbs the ultrasonic energy and becomes an activated excited state.
[0025] The ultrasonic atomizer 5 is connected to the high-voltage corona reaction chamber 6 th...
